Plot summary
Ellery Queen investigates a series of murders that seem to be related by an old rhyme: "Rich man, poor man, beggar man, thief, ...."

Literary significance and criticism
"The last full-fledged Wrightsville novel is as usual strong on characterizations. But some of the deductions made from the clues seem more speculative than logical."
