The Armchair Detective's Casebook

Learn to think like a detective — then crack three original cold cases with nothing but logic and a pencil. Inside this printable casebook: how investigators actually reason (the deduction loop, Occam's razor, and the Means-Motive-Opportunity framework), how to build a timeline that exposes the lie, forensics 101 (what fingerprints, DNA and time-of-death really prove), and statement analysis red flags. Then three fair-play solve-along cases — evidence, suspects and sealed solutions — plus printable case-board and evidence templates. Instant PDF. Print at home or read on any device.
