““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's looted, or the jewel-case is rifled, Or when the milk is missing, or another Peke's been stifled, Or the greenhouse glass is broken, and the trellis past repair - Ay, there's the wonder of the thing! Macavity's not there! And when the Foreign Office find a Treaty's gone astray, Or the Admiralty lose some plans and drawings by the way, There may be a scrap of paper in the hall or on the stair - But it's useless to investigate - Mcavity's not there! And when the loss has been disclosed, the Secret Service say: 'It must have been Macavity!' - but he's a mile away. You'll be sure to find him resting, or a-licking of his thumbs, Or engaged in doing complicated long-division sums. Macavity, Macavity, there's no one like Macavity, There never was a Cat of such deceitfulness and suavity. He always has an alibi, and one or two to spaer: At whatever time the deed took place - MACAVITY WASN'T THERE! And they say that all the Cats whose wicked deeds are widely known (I might mention Mungojerrie, I might mention Griddlebone) Are nothing more than agents for the Cat who all the time Just controls their operations: the Napoleon of Crime!””
