Freddie Troy has to come to grips with solving a string of murders as London threatens to fall under the thrall of organised crime, while in-between-times dealing with the vagaries of the affairs of those around him.
Troy’s family live life on a moral merry-go-round. His twin sisters, Sasha and Masha, were forces of nature. Sasha had married Viscount Darbishire, bringing her family's money to the rescue of an impoverished member of the aristocracy; impoverished even though he was ‘something in the City’. Masha, perhaps because of her father’s association with the newspaper business, had a husband who worked on the Sunday Post. Neither sister felt the need to be faithful, and at times they had shared more than just those sentiments.
His elder brother Rod was a Labour politician, voted into parliament in the immediate post-war elections.
All that was missing in this melange of ‘toffs’ and ambiguities was a wife for Troy – actually something he had acquired and then neglected.
This was all of little concern in a London where your behaviour and place in the world were determined by where you had come from.
Troy let none of this distract him from the job in hand; at times it could even offer him a distinct advantage.
