A Moment of Madness (S05E01)

A man emerges from a hotel elevator, drenched in blood. He rushes to the front desk, proclaiming in panic that he has taken a life. The frightened receptionist fumbles to dial 999 for help, but before she can complete the call, the man snatches the phone away. Meanwhile, unbeknownst to him, the police have already been alerted to the situation.
