The Problem of the Wire Cage (1939)

A rain-soaked tennis court replaces the conventional locked bedroom: a man has been strangled, yet the tracks seem to exclude a murderer’s approach. Read this impossible-crime variation for its sharply defined surface and spatial problem. The surrounding romantic entanglements take time, and the explanation invites careful mental reconstruction. It suits readers more interested in how a scene can be possible than in a large suspect list.
