The problem here is that one doesn’t normally fail to notice ones own name. Bob might have left the paper on the desk (without looking), but not tossed it. Thus, I think that someone else killed the man, took the real note, and left a fake implicating Bob. (Or maybe Bob is doing a double bluff!)
Of course, we also have Danger’s old standby: artificially limiting the suspect pool.
Personally, I think 2-10-0-2 is a better clue, but I don’t know to what, unless it is the safe combination. (The lengths of the letter runs.)
