(written from a Production point of view)
An actor traveling aboard the Enterprise may be a former governor who ordered a mass murder twenty years earlier.
The USS Enterprise is diverted three light years off of its scheduled course to Planet Q, lured by word of a new synthetic food which promises to ease chronic shortages on Cygnia Minor. But what Doctor Thomas Leighton actually wants to show his childhood friend Kirk is merely a traveling Shakespearean actor, Anton Karidian. Leighton believes Karidian to actually be Kodos the Executioner.
Kodos is notorious because he seized control of the doomed Earth Colony Tarsus IV in 2246 and ordered the execution of half its population of 8,000. Of the 4,000 survivors, only nine, including the young Kirk and Leighton, ever saw the face of the revolutionary governor.
Though convinced Kodos is long dead, Kirk does enough research to pique his curiosity about Leighton's claim. He returns to the planet in hopes of meeting Karidian in person. At a cocktail party held at the Leightons' home, Kirk meets Karidian's attractive daughter Lenore, and the two hit it off. They leave the party to stroll in Planet Q's desert, and come upon the body of their host Thomas Leighton.
Leighton's death makes Kirk take his dead friend's suspicions more seriously. After promising Leighton's distraught wife Martha that he will find out why her husband was killed, Kirk calls in a favor: he asks Jon Daily, commanding officer of the Astral Queen, to leave Planet Q orbit ahead of schedule and without notice. This strands the Karidian Players, who now have no choice but to ask for passage aboard the Enterprise.
Researching, Kirk reviews the list of the nine eyewitnesses, and discovers that Lieutenant Kevin Riley, a member of the Enterprise crew, is one of them. Despite the fact that Riley recently was promoted from engineering to communications, Kirk orders Spock to send Riley back down to engineering with the apparent intention of protecting him. When Spock asks why, pointing out that such action may be regarded by Riley as a demotion, Kirk refuses to explain.
Spock becomes concerned about the captain's behavior and confides in Dr. McCoy, while Kirk proceeds to get more involved with Lenore. Spock does his own research and learns enough to raise his own suspicions, including the disturbing fact that of the nine eyewitnesses who could positively identify Kodos, seven are now dead. And whenever one died, the Karidian Players were somewhere nearby. Only Kirk and Lieutenant Riley remain alive.
With a tray of food at his side Riley broods while alone in engineering and calls up the rec room pleading for company. Lieutenant Larry Matson turns over the intercom to Uhura, who serenades him by playing a Vulcan harp and singing "Beyond Antares". While Riley is distracted by her performance, someone sneaks into the room and emerges from the shadows to squirt something into his glass of milk. His spirits brightened, Riley reaches for his drink and takes a long gulp. Uhura finishes her song and Riley begins choking. Fortunately, Uhura's party realizes the situation and sends help in time to save him.
As Riley lies in critical condition on a bio-bed, Spock realizes that if he dies, Kirk will be the next target.
In McCoy's lab report on Riley's condition, he finds that the lieutenant had an appreciable amount of tetra-lubisol in his system, a milky lubricant used aboard the Enterprise. Spock is now certain that Riley was poisoned and with a reluctant McCoy confront Kirk in his quarters. Spock is now certain Karidian and Kodos are the same man, but Kirk remains unsure and has to make certain of it. McCoy asks Kirk what he will do if Kodos and Karidian are one and the same, inquiring if he will carry his head through the ship's corridors in triumph, noting that will not bring back any of the dead colonists. Kirk agrees but notes that "they may rest easier." Later, a similar discussion Kirk and Spock have is interrupted by the hum of an overloading phaser. Somewhere in Kirk's quarters is a potential explosive that can take out the entire deck. While Spock orders ship's personnel to clear the area, Kirk finds the overloading phaser in his quarters' red alert indicator and disposes of it seconds before it explodes.
Kirk is finally driven to confront Karidian, asking him point blank whether he is Kodos. Karidian gives him evasive answers, and after twenty years of playing parts that, of all things, he is tired. He does perform a short speech for the purposes of voice comparison with a piece of voice film in the Enterprise's database. This was apparently the speech made by Kodos condemning thousands of innocent people to death. Kirk mentions how Karidian barely looked at the text, hinting that it was already familiar to the actor, but Karidian simply states that he learns his parts quickly. Meanwhile, in sickbay, the recovering Lieutenant Riley overhears McCoy's log entry, learning that Karidian is suspected of being Kodos, the man who murdered Riley's family.
The voiceprint comparison is close, very close, but Kirk argues that when a man's life is at stake, very close isn't good enough.
The Karidian Players begin a presentation of Hamlet. Riley, with a stolen phaser, sneaks backstage. Kirk manages to talk him out of killing Karidian, who overhears their sotto voce conversation. Riley, with great reluctance, heads back to sickbay.
Kirk is still backstage when Karidian and his daughter Lenore discuss what he overheard during an act break. Trying to shield her from his past, Karidian attempts to pass off his distress as hearing the "voice of a part that he played long ago". But he is horrified when Lenore lovingly reveals that she knows all about his past deeds, and has already killed seven of the nine people who could identify him. Lenore goes on to tell him, innocently, that she will dispose of the remaining two after the performance.
Karidian is horrified that there is still more blood on "his" hands, but she proclaims that "they had to be silenced", and says, all with a smile on her face, that she buried those ghosts for him, and she has "saved" him. Karidian is devastated that all his attempts to prevent his past crimes from tainting his daughter have failed, and left him with nothing but a long legacy of murder.
Kirk appears from his hiding place to confront them. Lenore rebukes Kirk for interrupting her father before his appearance on stage. Kirk says she has killed seven innocent people, and she declares to Kirk that those people weren't innocent, they were "dangerous", and that she would have killed a world to protect her father.
Kirk summons security to take them into custody; Lenore snatches security officer Harrison's weapon and runs on stage. Her eyes show she's quite insane (reminiscent of Lady Macbeth and/or Ophelia). Karidian/Kodos, desperate there should be no more blood on his hands, steps between her and Kirk as she fires; the shot is fatal. Twenty years after earning the name, Kodos the Executioner is dead.
The death of her beloved father at her own hands sends Lenore over the edge. By the time Kirk leads her away, her tears have given way to laughter. Sometime later, after the performers have been dropped off at Benecia, McCoy promises Lenore will get the best of care, and that the last report of her is that she believes her father is still alive… performing to cheering audiences. McCoy suggests that Kirk did care for Lenore, which Kirk does not respond to, instead giving the order for Lieutenant Leslie to break orbit and go to warp. He does give McCoy a knowing look, which is all the answer the doctor needs.

Story and scriptEdit
- The title is a reference to the line from Hamlet: "The play's the thing wherein I'll catch the conscience of the King." (Act 2; Scene 2) This episode shares many plot elements with the play: A leader's troubled conscience, his crimes being exposed during a play, and a daughter going insane (or more so, in Lenore's case) after the accidental killing of her father. Lenore recites the lines leading up to and including these over her father's body.
- The most overt reference is in the teaser. The Karidian Company is performing a scene from Macbeth, where the title character (played by Karidian) murders King Duncan and utters the line, "Will all Neptune's great ocean wash this blood clean from my hands?"
- In the script, the teaser started with a view of the city on Planet Q, with a poster advertising the Karidian Company of Players superimposed over it, then dissolving into the performance of Macbeth. It was probably director Gerd Oswald who decided to start the episode in medias res instead, with the shot of the dagger, which seemed to be more effective on screen. 
- A line scripted, but cut from the episode established that Kirk was a midshipman, fresh out of the Academy when he was stationed on Tarsus IV and witnessed the massacre. Since it happened twenty years before the events of this episode, this would have indicated that Kirk is somewhat older than what was later established in "The Deadly Years". 
- The phaser overload emergency is the only known instance when a double red alert is declared. However, in James Blish's adaptation of "Court Martial" in Star Trek 2, he has Kirk ordering a red alert and then a double red alert during the ion storm – as opposed to the yellow alert and red alert that were depicted on screen. "Red alert" and "double red alert" were used in the final draft of that episode's script but were changed on-set before filming.
- A scene of crewmen watching the performance of Hamlet on the bridge was filmed, but cut from the episode. 
- Another scene which was cut showed Lenore resting in sickbay after her mental breakdown. 
- This episode contains Star Trek's first direct reference to eugenics, although there is an oblique reference in "What Are Little Girls Made Of?". Spock declares Kodos' martial rule of Tarsus IV to have been an experiment in eugenics, causing McCoy to note that his wasn't the first such experiment.
- Kirk refers to Riley as a lieutenant in the "Star Service" – another early name for Starfleet.
- This is the only episode to depict nighttime on the Enterprise (Kirk says that conditions of night and day are approximated as closely as possible aboard ship.) However, in both "Is There in Truth No Beauty?" and "Requiem for Methuselah", various crewmembers bid each other goodnight.
- This is the only episode to depict the observation deck. It is also the only episode in which no one is seen in the act of beaming.
Cast and charactersEdit
- James Doohan (Scott) and George Takei (Sulu) do not appear in this episode.
- Eddie Paskey's character name, Leslie, is finally established in this episode.
- Her walk-on bridge appearance and stern look at Lenore is Grace Lee Whitney's last appearance in the series. However, viewers see her for the last time in "Balance of Terror", as that episode was aired a week later.
- In the script, Yeoman Rand interrupted Kirk and Lenore on the observation deck to bring Kirk a report. However this event was omitted from the episode, 28 years later it was featured (as a dream flashback) in the comic book story, "The Dream Walkers".
- Whitney was already notified that she was fired from the series a week before filming on this episode began. Her limited walk-on scene was the last she had to film for Star Trek, before her return in Star Trek: The Motion Picture. She recalled, "By that time, I had already been written out of the show. I did the scene sober, but after shooting my walk-on, I went out to a liquor store, bought a bottle of wine, and brought it back to my dressing room. That day, I drank. I couldn't deal with the fact that I wasn't going to be on the show anymore, so I drank to anesthetize the pain. That was the only time I ever brought a bottle unto the studio lot." (The Longest Trek: My Tour of the Galaxy, p. 102)
- In the original draft, a "Lieutenant Robert Daiken" was the young man whose parents had been murdered by Kodos. When Bruce Hyde was cast in the role, the staff realized that he played the character Kevin Riley in "The Naked Time" and re-wrote the role to feature Riley instead. Riley was a navigator in the former episode, but in this one he's a communications officer who at one time was transferred from engineering, but he still wears the gold command shirt. 
- This is the first episode featuring the computer voice (although a talking computer was featured in "Mudd's Women").
- Joseph Mullendore's score for this episode was heard again in "Court Martial", "Shore Leave", "Space Seed", "The City on the Edge of Forever", and in the teaser of "The Return of the Archons".
- The Star Trek theme song is performed by the lounge band at Tom Leighton's party. This is the first time the Star Trek theme has been played as "source music". The other times this occurs in the original series is later in the episode when Kirk is speaking to Lenore in Karidian's cabin, when Areel Shaw enters the bar in "Court Martial", and when Kirk, McCoy, and Tonia Barrows run to Sulu's position in "Shore Leave".
- The dreamlike song sung by Uhura is "Beyond Antares". Nichelle Nichols got to interact with the Vulcan harp again in "Elaan of Troyius", but that scene was cut. In ""The Changeling"" she sings a portion of that song again, without an instrument, before Nomad interrupts her.
Sets, props, and costumesEdit
- Kirk's quarters are labeled as "3F 121".
- Guest star Barbara Anderson (Lenore Karidian) shares the record (with Ricardo Montalban and Joan Collins) for the most costumes worn in a single Trek episode by a guest star (six). She wears a maroon-colored dress for her Lady Macbeth costume, a blue dress with a veil at the party thrown by the Leightons, a fur mini-skirt dress when arriving on the Enterprise, a greenish multicolored mantle on the observation deck, a black and red evening dress when Kirk visits the Karidians in their quarters, and, finally, her yellow and lavender Ophelia costume. It could even be argued that the veil she wears while walking with Kirk just before discovering Tom Leighton's body could be considered a seventh costume.
- In the original series, this is the only appearance of the observation deck. It overlooks the shuttlebay, called here the "Flight Deck".
- McCoy's cabinet has two skulls in it for the first time in this episode.
- The pressure vent disposal drawer, into which Kirk places the overloading phaser, was later used by Lazarus to cause a fire in "The Alternative Factor". The small drawer was filled with circuits for that scene.
- In the scene where security guards are searching for Kevin Riley in the corridors, rectangular seams are visible in the floor. This is where the grates visible in "Charlie X" and other early episodes were eliminated and filled in with the corridor floor material.
- The equipment-filled alcove that McCoy and Spock pass in the corridor as they discuss Kodos the Executioner is labeled "Engineering Circuit Bay G-121". This sign was later placed next to the Jefferies tube in season two.
- The city in the background out Tom Leighton's window is the same one used as Mojave in "The Cage". The window itself was used in the Delta Vega lithium cracking station set in "Where No Man Has Gone Before".
- Unlike most of the doors seen in the original series, the one to Leighton' house is operated manually and swings open and shut. Similar examples are seen in the courtroom in Court Martial and in Captain Pike's ward in The Menagerie, Part 1.
- The chair in which Leighton sits just before he rises to reveal his black facial patch was later seen with its mate in Chief Vanderburg's office in "The Devil in the Dark".
- The ship's theater is a redress of the engineering set. Pieces of the ship's gymnasium are hanging on the walls, and the ceiling can be seen of this set in one of three glimpses in the first season.
- The observation deck is a redress of the Romulan bridge set from "Balance of Terror".
- The face covering Tom Leighton wore to hide his injuries is almost identical to one worn by a character in "The Duplicate Man", a 1964 episode of The Outer Limits which was also directed by Gerd Oswald.(citation needed • edit)
- The preview contains a Captain's Log recorded solely for the preview: "Captain's log, stardate 2817.2. Suspicion that a famous actor is, in reality, Kodos the mass executioner places the Enterprise and her crew in grave danger."
- The preview for this episode features an alternate edit of Kirk searching for the overloaded phaser in his quarters. It was unused because the plywood under the mattress of his bunk was visible.(citation needed • edit)
Reception and legacyEdit
- This episode was among the lowest in ratings during the first season, mainly due to the fact that it was "too talky" with no action scenes, and didn't feature any "monster" or "sci-fi gimmick". Hence, it was decided not to give "The Conscience of the King" a repeat broadcast. (These Are the Voyages: TOS Season One, p. 299)
- Director Gerd Oswald recalled this episode as "A very intriguing idea. A good story.". (These Are the Voyages: TOS Season One, p. 299)
- Matt Groening, creator of The Simpsons named his recurring alien characters Kodos and Kang after the characters in this episode and "Day of the Dove", respectively.
- Stating that this was his favorite episode of TOS, writer Ronald D. Moore commented:
- I liked the backstory of Kirk as a young man caught up in a revolution and the nightmarish slaughter by Governor Kodos. I liked the Shakespearean overtones to the episode as well as the use of the plays themselves. And I absolutely loved Kirk in this episode – a troubled man haunted by the shadows of the past, a man willing to lure Karidian to his ship under false pretenses, willing to do one of his more cold-blooded seductions on Lenore, willing to fight with his two closest friends, and risk his entire command in the name of justice. Or was it vengeance? Kirk's aware of his own lack of objectivity, his own flaws to be in this hunt for a killer, but he cannot push the burden away and refuses pull back from his quest to track down Kodos no matter what the cost. It also has some of my favorite lines in TOS.
- The scene with Spock and McCoy in Kirk's quarters is one of the series' highlights. The brooding tone and the morally ambiguous nature of the drama fascinated me and definitely influenced my thinking as to what Trek could and should be all about. (AOL chat, 1997)
- Consequently, in his re-imagined version of Battlestar Galactica, executive producer Ronald D. Moore named the prison barge Astral Queen after the ship commanded in this episode by Jon Daily.(citation needed • edit)
- The Enterprise fourth season episode "In a Mirror, Darkly, Part II" shows the future biographical information displayed for Hoshi Sato, written by Mike Sussman. A portion of the bio written by Sussman but not shown on screen would have stated that Sato was one of the 4,000 people killed by Kodos on the Tarsus colony. (Sussman noted that he never intended for the data to be readable on screen, and on his website he says to take that biographical information with "a grain of salt.")
