Tool Mark covers crimes solved before modern forensics, from the 1880s to the 1950s. Each case turned on something small and physical: a laundry mark, a serial number, the grain of a plank.
Episodes draw on court records, inquest findings and reporting from the time, with no reconstructions and no invented dialogue.
