'He's outwardly respectable. (They say he cheats at cards.)
And his footprints are not found in any file of Scotland Yard's.
And when the larder is looted, or the jewel-case is rifled,
Or when the milk is missing, or another Peke's been stifled,
Or when the greenhouse glass is broken, and the trellis past repair-
Ay, there's the wonder of the thing! Macavity's not there!'
Macavity: The Mystery Cat
