Professor Augustus S. F. X. Van Dusen, with the help of his friend newspaper reporter Hutchison Hatch, solves a variety of mysteries using cold, hard logic. No matter how twisted the trail of clues or how clever the perpetrator, Professor Van Dusen, aptly dubbed “The Thinking Machine”, reminds us that “two and two make four, not some times, but all the time”.

So when a woman begs a surgeon to amputate part of her perfectly healthy finger, or when a pearl necklace disappears from a woman’s neck at a party, or when a man presents the court with his “perfect” alibi, The Thinking Machine focuses on the facts and methodically investigates all of the (logical) possibilities.

In fact, the author’s own wife, May Futrelle, set out to stump her husband’s talented detective with an unsolvable mystery of her own, in which a lonely traveler takes a wrong turn and ends up in a mysterious house. Was she successful? Discover for yourself in this original audio compilation produced by Skyboat Media for Blackstone Publishing.
