The Freezing Hold of Barge Heron

6 min

Barge Heron has been in locked winter mooring at Fossdyke Basin since the navigation closed in November. When basin warden Nora Petch made her weekly round, she found the forward hold's iron bar had been sawn partway through and bent aside, a heavy cargo crate inside the hold had been shifted from its stowed position, and the spare key from the warden's key-board was missing from its hook. Someone — almost certainly a member of the basin's own work crew — had engineered an exit from the locked hold. Petch has asked you to establish the precise order in which the three escape methods were employed and the surrounding events unfolded.
