They Do It With Mirrors by Agatha Christie

Edgar pretended to be mentally unsound but Miss Marple found his play-acting overly exaggerated and this made her suspicious. Serrocold created a tape of his responses. Hoewever, in this case, Edgar did not have to mimic Serrocold's voice. Like in the original, Edgar staged the argument in the study while Lewis sneaked out and shot Christian.They enlisted the willing help of Edgar, who looks on Serrocold as a father. Christian had found out about Serrocold and Hargrove's scheme so they conspired to kill him. She identifies Lewis Serrocold as Gulbrandsen's killer. It is left to Miss Marple to unmask the murderer during the denouement.Hargrove was in the room with all the others listening to Edgar shouting at Serrocold. While this looks final, it is not as neither Hargrove nor Edgar could have killer Gulbrandsen.

The boat sinks, he falls into the water and drowns. After nearly breaking down during questioning, he runs off and tries to row across the lake in a rotten boat. There is a final drowning scene like in the original but only Edgar is involved.His car crashes and he dies in the subsequent explosion. He attmepts to leave the estate but the police close the gate in time. He pulls out a gun and takes Miss Marple hostage and then tries to escape in a car.
