He was also at the heart of the city's murky, post-war underworld. In Slumlord, Neil Root pulls back the curtain on this seedy world to paint a portrait of a fascinating man whose path intersected with figures as diverse as Christine Keeler, the glamorous society girl at the heart of the Profumo Scandal, and Michael X, the Black Power activist who later went on to be hanged for double murder.

Ruthless in his ambition, Rachman was the archetype of the exploitative landlord, and a man who was willing to use the prejudices of his time in order to maximise profits. He is also a compelling leading man in a story of post-war London, a city where, among the grime and the rubble, fortunes could be made. You just had to hold your nose, abandon your morals and be willing to take from those less fortunate.
