'They say I've killed 40 people and who am I to disagree? I've always liked even numbers.'

Branded the dentist for using pliers to extract the teeth of those who owed money to his boss Charlie Richardson, Frankie Fraser was labelled the most dangerous man in Britain by two Home Secretaries. He is famous for his crimes, many of which have entered gangster folklore. In these diaries, however, originally published when he was 78, Mad Frank delved into areas he had never chosen, or dared, to talk about before.

His day-by-day entries record unsolved murders, shoot-outs, crooked coppers, bribery, extortion, wrongful convictions, and even sex in prison. And by contrast, he also opens up with personal memories of growing up in poverty, in London's East End, and the reality of having to steal food to feed the family.

Frankie Frasier died in 2014, and this rare True Crime classic is first-hand history at its most compelling.
