Petersen confronts Murchison in his office to prove her hunch; she relates Ballantyne's dream to Murchison, getting him to admit that the masked proprietor likely represents himself. She presents her accusation, and Murchison replies that she got every detail right but one: he still has the revolver, and draws it on her. Petersen reasons with Murchison as she walks out of his office to phone the police, pointing out that while he could plea insanity and get a lesser charge for Edwardes' murder, shooting her would guarantee his execution. She leaves the office, and Murchison turns the gun on himself.
