Charlie Richardson also said that working legitimately in the City was more crooked than the crime he had been involved in previously.
" Richardson's autobiography, My Manor, was published in 1992, and he went into legitimate business in the City ( after release from prison) , which he claimed was much more dishonest than anything he had been involved in before."
