The problem of Cell 13

A collection of short detective tales follows a brilliant logician called the Thinking Machine as he confronts baffling puzzles—locked-cell escapes, impossible thefts, mysterious disappearances, and uncanny clues—and solves them by applying rigorous deduction and practical experimentation. Each story sets up a seemingly insoluble problem, traces systematic reasoning and occasional mechanical ingenuity, and reveals solutions grounded in overlooked physical or procedural possibilities. Recurring motifs include the scientific method, clever contrivances, and the demonstration that careful analysis can reduce apparent impossibilities to straightforward explanations.
