Macavity is an elusive master criminal who leaves no evidence after he commits a crime. He baffles Scotland Yard police and the flying squad as he disappears before their arrival to the scene of crime. He defies law of gravity and his powers of levitation make me fakir stare with wonder. Macavity loots the larder. He ransacks the jewel case. He is an elusive criminal who escapes from the spot of crime before the flying squad or Scotland Yard reach there. He breaks every human law and laws of gravity. He breaks greenhouse glasses. He steals stealthily into . the kitchen and empties milk. When an important treaty in the embassy is missing or. when the admiralty loses some plans or drawings, the investigation terms conclude that it is the work of Macavity. But Macavity, as a wonder of wonders, would be miles away relaxing somewhere.
