He always has an alibi, and one or two to spare: At whatever time the deed took place- Macavity wasn't there.

Macavity, Macavity, there's no on like Macavity, He's broken every human law, he breaks the law of gravity.

Macavity, Macavity, there's no one like Macavity, For he's a fiend in feline shape, a monster of depravity. You may meet him in a by-street, you may see him in…

He's the bafflement of Scotland Yard, the Flying Squad's despair: For when they reach the scene of crime - Macavity's not there!
