Professor Layton has been something of a sleeper hit on the Nintendo 3DS, with several games replete with brain-teasing, riddle-solving action. But now it looks like the good Professor may be applying his mental mettle to a more literal arena.

True detectives will, at this point, realise that this isn’t absolute declarative evidence of Professor Layton in smash; it’s possible Mr Miller is just voicing a trophy or another character, and there has been no official word from Nintendo or Professor Layton developer Level-5

So I’m afraid the case has run cold for now, but watch this space and I’m sure new leads will appear soon.

Dismissed, detectives.
