officials corroborate the details of Lennox's death, Marlowe returns to the Wade house. A party breaks up after an argument over Roger's unpaid bill from the detoxification clinic. Later that night, Eileen and Marlowe are interrupted when she sees a drunken Roger wandering into the sea; before they can stop him, he vanishes into the ocean and is presumed to have drowned by police. Eileen confesses that Roger had been having an affair with Sylvia, and might have killed her. Marlowe tells this to the police, who tell him that they already knew that Roger Wade had met with Sylvia Lennox before going to the clinic. Marlowe is then brought to a meeting with Augustine, and threatened before his missing money is returned by someone else. While leaving, Marlowe sees Eileen driving away in her open topped Mercedes-Benz 450SL. While running after her, he is struck by a car and hospitalized. Waking up, he is given a harmonica by the heavily-bandaged patient in the next bed. Returning to Malibu, he finds the Wade house being packed up by a real estate company and Eileen gone. He returns to Mexico, where he bribes local officials into revealing that they had been paid to fake Terry Lennox's death of an apparent suicide. Marlowe finds Terry in a Mexican villa, who admits to killing Sylvia and reveals that he is having an affair with Eileen. Roger had discovered the affair and disclosed it to Sylvia, after which Terry killed her in the course of a violent argument. Terry gloats that no one cares about the case since he is legally dead, causing Marlowe to fatally shoot Terry. As Marlowe walks away, he passes Eileen, who is on her way to meeting Terry. Marlowe pulls out his harmonica and plays it while strolling jauntily down the road.
