John Carstairs was much agitated when he read of a "society burglar" who had been making wholesale inroads upon the rich homes in the vicinity. When he showed the article to his daughter, Diana, and his son, Jack, Diana proposed that they give a house party and hold a burglar hunt. Two of the guests at the house party were Larry Hunter and Cyril Cadwalader, rivals for Diana's hand. Jack Carstairs, on mischief bent, sent notes, purporting to come from Diana, saying to each that she feared the other was the "gentleman burglar." So each was eager to catch the other red-handed. Jack left a note on the door saying, "I am going to rob this house tonight." Its discovery caused great confusion. That night John Carstairs locked up all the jewels of the guests in the family safe and mounted guard himself, armed with everything from a gun to a watchman's rattle. But Jack, while his father slept, rifled the safe and concealed half the jewels in Hunter's pocket and the rest in Cadwalader's clothes. When the robbery was discovered both Larry and Cyril were bent on fastening the crime on each other. But both were discomfited when jewels were found in their pockets. The crowning discomfiture came when they found that a third suitor for Diana's hand was the favored one. Jack had his fun all right, but he got a whipping.
