First light in the deserted City. An explosion. Another safe robbery. It's at a London travel agents where police find a hole in the floor, a blown safe, but also a dead man. He's a known safe blower, Alfie. Forensic evidence shows he'd been hit on the back of his head.
Police follow Alfie's wife to some advantage. She's spotted receiving the old envelope with banknotes routine. But then she too is killed. Rather careless, the killer has left a fag behind at the scene of this crime, with lipstick of a tangerine colour on. Careless, but remember this is a true story. This matches some lipstick on Alfie's hankie.
A trawl through the Yard's files shows that the man who was paying off Alfie's wife was a Polish fur trader (Carl Jaffe). Spt Hicks enlists the help of 'Fingers' who joins the fur trade. The gang need a new safe cracker! Eventually Fingers gets roped in for a job, but is overheard informing on the gang and the job is switched at the last moment. Alas poor Fingers! He's shot as the police pounce. The background to the killings was a love triangle amongst the villains. Arrested was "one of the most dangerous women criminals," pronounces Edgar impressively, "in the annals of Scotland Yard."
