Capt Kirk is informed by an old friend, a colonial governor, that a Shakespearean acting troupe on his world is led by a man once known as Kodos the Executioner. Kodos had most of his colony killed when food supplies ran short rather than have so many starve. The only surviving witnesses to his actual appearance are Kirk, his friend, and a young crewman on the Enterprise. Kirk dismisses his friend's accusations until he turns up murdered, and his crewman nearly so. Karidian denies he's Kodos. Is he telling the truth? If so, who is behind the murders?

Did You Know?


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. See more »


Several characters, including Kirk, state that if "the last few eyewitnesses" who know what Kodos looked like were to die, than that knowledge will be lost. But Kirk finds Kodos' mug shots and voice prints easily enough in Starfleet's files to compare with Anton Karidian. See more »

Murder, Mayhem, and a Play to Catch the Conscience of the King
26 April 2014 | by (United States) – See all my reviews

Captain Kirk is such a loose cannon sometimes. He is unable to repress his "maleness" in virtually any setting. A Shakespearean troupe traveling the galaxy (an intriguing concept) lands on the Enterprise. In exchange for transport, they agree to perform for the crew. As time goes on, it is revealed that the principle actor and the father of a beautiful daughter may be a murderer of mass proportions. The task then is to somehow prove this. On board is a young man whose family was killed by this person. The fun thing is that there is a kind of Agatha Christie like parry and thrust going on, including an attempted poisoning. Kirk, as he always does, pursues the beautiful daughter. Apparently, William Shatner was the perfect choice for the Kirk portrayed in this series. Anyway, things aren't always as they seem to be and we are treated to some interesting twists and turns.
