that Mark and Josie were married. Besides wanting Conway dead, upon learning that Conway planned to adopt Ruby, they made the double murder plan. Mark lured Pamela to the hotel for the fictitious screen test. Josie dressed her, dyed her hair, and made her up to resemble Ruby, then drugged her. During the bridge game, Mark took a break, taking the drugged Pamela to Blake's hearth rug, where he strangled her with her belt. Just before midnight, when Ruby went up to change for the exhibition dance, Josie followed her and killed her by injection or a blow. After the midnight dance, she took Ruby, dressed in Pamela’s clothes, in Bartlett's car to the quarry where she set fire to the car. During the police interrogation, Mark breaks down and confesses all the details. Adelaide says she has agreed to marry her long-time suitor, Hugo, which pleases Conway. His new will settles cash on Adelaide and leaves the rest to her son Peter. Characters Miss Marple: resident of village of Saint Mary Mead who has much experience in solving murders.
