Pearson may be an authority on the London underworld scene. But in The Profession of violence he famously stated that Angelo Bruno was the mafia boss of New York. So I hope he's done some research before taking on this subject.
Wilf Pine is well respected, i would not say he was in the top tier if you know what i mean. He was friendly with the Krays, the Richardsons, The Nash family, and even todays Adams family
