John Dickson Carr is famous for his puzzling "impossible crime" plots, in which corpses are discovered in scenarios that seem to lack any logical explanation, concealing clues as to how the murder was committed and how the body arrived in its current setting.

John Dickson Carr is famous for his puzzling "impossible crime" plots, in which corpses are discovered in scenarios that seem to lack any logical explanation, concealing clues as to how the murder was committed and how the body arrived in its current setting.

Among all of Carr's ingenious crime scenes, the present case is one of his best known: a dead man is found strangled in the middle of a clay tennis court, just after a storm. In the damp dirt, there is one set of footsteps-his own-leading back to the grass; the court is otherwise untouched. There are no trees above from which the body may have fallen and no other visible means by which it may have been transported to its final resting place. Before determining the perpetrator of the strangulation, the local authorities are first confronted by the utter implausibility of the location-two interlocking questions puzzling enough to stump even the most seasoned inspector.
