But Littlechild didn't think Tumblety was the Ripper.
In his three-page letter, which covered a number of Ripper-related subjects, Littlechild only mentions Tumblety in response to something raised by his correspondent: has he heard of a 'Dr D' in relation to Ripper suspects?
No, writes Littlechild, but there was a 'Dr T' who was a 'likely' suspect. However, the ex-chief inspector goes on to say that although Tumblety was a 'sycopathia sexualis' subject, he was not a sadist - which he, Littlechild, believes the Ripper was.
Littlechild also mistakenly indicates that Tumblety disappeared after the killings. Not true. In fact, Tumblety took advantage of a move in his court date to skip bail and escape gross indecency charges (for homosexual acts); and he then went to ground in New York, probably confident that he couldn't be extradited on such minor charges.
So Littlechild, while agreeing that Tumblety was a suspect, evidently wasn't sufficiently interested in him to investigate what happened to him after he left London.
Tumblety was a nasty piece of work, by all accounts, but he sounds too flamboyant and easily recognisable to be the Ripper. And I know it's an established fact that he made no secret of disliking prostitutes and hating women, but he was gay, after all, so it's difficult to imagine him being *that* bothered that his wife was a former prostitute. It's quite possible that all his misogyny was just talk.
I'm interested in the 'two cheap, imitation rings' that you describe, though. Whereabouts are they mentioned?
