Professor Augustus Van Dusen: 49 Detective Mysteries in One Edition gathers the celebrated cases of "The Thinking Machine," a diminutive, irascible scientist whose icy logic penetrates locked rooms, impossible disappearances, cryptograms, and criminal stratagems. Written in the brisk, puzzle-centered manner of early twentieth-century magazine fiction, these stories belong to the golden prehistory of the formal detective tale, standing between Poe's ratiocination and the later elegance of Christie and Queen. Futrelle's prose is economical, theatrical, and ingeniously plotted. Jacques Futrelle (1875–1912), an American journalist, dramatist, and fiction writer, brought to detective literature the habits of the newsroom: speed, clarity, public intrigue, and an appetite for startling problems. His fascination with science, reason, and intellectual contest shaped Van Dusen into a memorable emblem of modern rationalism. Futrelle's own life, cut short in the sinking of the Titanic, lends his compact achievement a poignant historical resonance. This volume is recommended to readers who delight in cerebral mysteries, classical clueing, and the spectacle of reason imposed upon chaos. Though some social attitudes reflect their period, the stories remain absorbing for their ingenuity and historical importance. For students of detective fiction, this collection is indispensable; for general readers, it offers elegant, addictive entertainment.
