Fall Guy

Sometimes, the police simply are not going to stop investigating a crime until they find someone to arrest. In this case, even if you've pulled off The Perfect Crime, the only way to be certain of getting away with it is by setting up some other sap to take the fall for you.

Sometimes the Fall Guy is an accomplice who takes on this scapegoat role willingly. Other times, when you have drawn up plans with the brilliant clockwork evil of The Chessmaster, you might choose a Fall Guy—whether an accomplice of yours, or someone completely innocent—by tricking this Unwitting Pawn into taking the blame.

Maybe you choose the guy no one's going to believe. Better yet, you choose a well-meaning sap whose fears and goals you've been able to manipulate via Flaw Exploitation. Alternately, you could pull off a Deceased Fall Guy Gambit, since a dead man can't defend himself.

Not to be confused with a television series.
