The Mystery at Number 31, New Inn, a classic mystery novel by R. Austin Freeman, relates a puzzling tale from an earlier century. In the grand tradition of the great sleuths brought to life by Sir Arthur Conan Doyle comes John Thorndyke, cerebral, meticulous, British, . . . and undestimated. A contested will and an unusual sickness have no apparent connection until John Thorndyke and Dr. Jervis collaborate on a labyrinth of clues, including broken glass, an upside down picture, a veiled woman, and a box of candles. This puzzle is solved with inductive reasoning and careful use of the scientific method.
