Mark is having a hard time preparing for a magic show for the child patients. He first misplaces the key to the chest he locked Steve in, then he learns janitor Jim Briggs, an amateur magician himself, was killed surfing; his estranged married twin brother Jeff turns up just then. Mark soon suspects from various details it might just be that Jim killed his brother to take his place, which sister-in-law Dina laughs away and suggests to Steve to take fingerprints, and then tells Jim she knew since the first day and was glad to be rid of Jeff. According to Jeff's will it would spare her from losing two thirds of the estate to his sons from his first marriage. The Sloanes push on, helped by Jeff's secretary and mistress Teri Deegan.
