The Golden Plum Substitution

4 min

On a Friday in late July 1971, a pallet of premium Golden Plum preserves bearing the Harwick Cooperative's gold-seal label was dispatched to a London grocer — but when the crates arrived, the jars contained cheap, overripe greengage pulp. Quality inspector Mabel Crudd was found dead at her workstation the same day, and the cooperative's foreman, Terrence Oast, is suspected of orchestrating the substitution. Your task is to reconstruct the exact sequence of six events that morning, using only the forensic clues recovered from the canning floor.
