The son of a police detective solves baffling crimes.
The third TV adaptation of the adventures of super-sleuth Ellery Queen, this time set during the 1940s. Queen was a mystery writer who assisted his father, a detective with the New York Police Department, in solving murders. Sgt. Velie was Inspector Queen's assistant and Simon Brimmer a rival detective. Queen's methods were arcane and intellectual rather than action oriented, and he always astounded his father by arriving at a correct solution by purely deductive reasoning. In this version, just before he revealed his solution to the crime, Queen always turned to the camera and asked the TV audience if they had figured out the identity of the killer yet -- they had all the clues -- because he was about to reveal the correct killer as we met the entire slew of suspects in one room for the ending.
