Alfred Hitchcock Presents: 3x3

The Perfect Crime

An arrogant detective Charles Courtney prides himself on never having committed a single mistake in his long and distinguished career. He keeps a shelf of labeled mementos from each of his cases. On the shelf there is an open space and a blank tag for what Courtney calls “”The Perfect Crime””. One day a defense lawyer stuns Courtney when he confronts him with evidence that the detective helped convict an innocent man who has since been executed. Courtney kills the lawyer, bakes him in a pottery kiln, and places the vase in the open space on his shelf as a memento to his perfect crime.
