Worldbuilding
Richard Blaney's troubled world takes shape: he's fired from his pub job for drinking the inventory, visits his successful friend Bob Rusk at Covent Garden, and reconnects with his ex-wife Brenda who runs a matrimonial agency. Blaney is portrayed as hot-tempered and unlucky, but fundamentally decent.
Disruption

Inspector Oxford prosecutes the case, but small doubts begin to form as his wife's amateur detective instincts question the evidence.
Collapse
