Directed by: Alan Rafkin
Starring: Don Knotts, Liam Redmond, Dick Sargent, Joan Staley
Revealing mistake: After Luther faints from seeing the shears in the painting of Mrs. Simmons, the beam of light from his flashlight continues to move side to side, but Luther's flashlight is in his hand, unmoving.
Revealing mistake: The view of the village of Rachel outside Nick Simmons' hotel window is obviously a picture.
Continuity mistake: When Don Knotts (Luther) is in the Simmons' mansion, his flashlight moves when the light from the flashlight does not. One time, while leaving a room, his flashlight points away from him, but the light actually shines on him.
Luther Heggs: Calm? Do "murder" and "calm" go together? Calm and murder? Murder?
Trivia: The paintings of Mrs. Simmons are actually two different women. Don't know who the first one is (the one with the shears and blood), but the second one, when Luther brings everyone with him to the mansion, is actually taken from a painting of a mother and daughter entitled "Mrs. Fiske Warren and her daughter Rachel."
