That night, Hugh somehow manages to get out of his locked room and is found outside Diana's room, a bloodied knife in his hands from having killed a cat.

Stoddart had been summoned after Mrs Grace had an argument with her boyfriend, Anthony Hawker. She tried to shoot him as he left the flat, and inflicted a flesh wound on a passing tramp. Stoddart patched up the tramp who has accepted a
