I still think it should be that the deaf guy and mute guy are the same. That’s the only one that has the requisite “twist” feel to it. I know, I know. The riddle specified that there are 3 separate men. But that feels like a riddlish answer! Anything else is a huge letdown.
Seems to me, like you couldn’t solve it yourself, and if you’d gotten an answer from this fourm, then you’d already have admitted defeat. Anyone can Google seach for the general question and this forum will pop-up, so you’ll be found out sooner or later. Might as well own up, and take the medicine.
Oh, and uh, BUMP for the answer. That’s why I really posted.
