Sort of the same problem with those, though.

I mean, at least he probably goes to the barber's once a month or once a fortnight, even, if you're lucky. But how often does any particular bloke go to his tailor's? or the bootmaker's? They'd be terrific places to catch him if you knew he'd be going there before November, yeah?

Maybe there's a way to plant the idea he needs something from one of them, but if you've got that close to him, you could probably take him down then and there.
