Once is a chance, twice is a coincidence, third time is a pattern.

Ron Iddles claims old crook, Alfred Hugh Gay named Norman Lee as Mr. Cruel. Alf stated to Ron that his friend Normie had confessed to killing Karmein Chan, and that he had been to his house and that it matched the description of Mr. Cruel’s detention house but none of Alf’s story stacks up. Coincidentally , it is Alf  himself that has connections to every crime site location.
