The problem of Cell 13

A little about the story

Professor Augustus S. F. X. Van Dusen is prepared to stake his reputation on the power of clear reasoning. When a discussion turns to the apparent impossibility of escaping a closely guarded prison, he accepts the challenge and agrees to be confined under conditions designed to exclude every easy advantage. The authorities can inspect the cell, supervise his possessions, and watch the routine; they cannot so easily control the possibilities he is considering.

The central mystery reverses the familiar locked-room problem. Rather than asking how a criminal entered or escaped after a crime, readers watch an investigator test what imprisonment really makes impossible. Jacques Futrelle combines patient observation with the theater of an unusually self-assured intelligence, making minor practical details feel potentially decisive. The featured tale supplies the volume’s title, while the accompanying Thinking Machine stories offer further encounters with puzzling disappearances, technical complications, and crimes that resist their first, most comfortable explanation.
