That Criminals Revised page is a gem. I like the detail that, in 1882, he was charged with “the larceny of a watch on a street car” - exactly the same crime that he committed at Cosham, but thirty years later and on another continent.
I emailed briefly with Jerry, whose project Criminals Revised is, and he said Rayment was “a sneak thief, adept at distraction of people and surreptitious snatching of objects. In forgery gangs, his role was undoubtedly to purloin copies of check/bond blanks, to be given to a penman to alter.”
