Pamela Guest who was raped 40 years ago discovers her attacker was the father of the 'Soho House murderer' after stumbling across the story in a magazine By Rachel Quigley UPDATED: 16:23, 8 July 2013 Victim: Pamela Guest said she was raped by Joseph Brooks 40 years ago when she went to his apartment for an audition An actress who claims she was raped by Academy Award-winning songwriter Joseph Brooks has spoken out for the first time about the attack, which took place more than 40 years ago. Pamela Guest did not know the real name of the man who called himself Patrick Mannion when she went to his Michigan apartment aged 21 under the guise of an audition in the early 1970s. She only learned his true identity in April, when she was at her home in California reading about the murder of swimsuit designer Sylvie Cachay, allegedly at the hands of her ex-boyfriend Joseph Brooks. Sylvie's body was found submerged in a bath tub in Manhattan's SoHo House in December 2010. She had been strangled and drowned after a violent argument with her boyfriend. The article included a picture of Brooks' father Joseph and the sight of it, along with the fact that he wrote the Maxwell House jingle 'Good to the Last Drop Feeling' brought all the terrible memories flooding back. 'I got chills up and down my body and I started crying,' she told the New York Times, explaining she knew immediately that it was the man who raped her all those years ago. It was like a picture developing. When I found out the M.O. and about the woman, it was the first piece of "maybe this is the same guy?" - and then the jingles. Recounting the horrible incident, the mother-of-two said she had suspected her rapist gave her a false name but distinctly remembers the Maxwell House jingle. 'That's such a specific thing. I remember him trying to impress me with what a big deal he was,' she said. Joseph Brooks committed suicide in 2011, two years after he was charged with molesting 13 women under the guise of auditioning them for roles in his movies, then drugging and sexually assaulting them. Accused: Oscar-winning composer Joseph Brooks was facing trial for rape when he was found dead Son: Nicholas Brooks, 26, was charged with murder after his girlfriend Sylvie Cachay was discovered dead at the Soho House in NYC in 2010 His female accomplice Shawni Lucier pleaded guilty to charges of helping him facilitate some of the attacks, and admitted helping him entice ten women to his Manhattan home knowing he intended to assault them. This also fits in with Guest's account of what happened when she went for an audition in an apartment on the outskirts of Ann Arbor when she was a student at the University of Michigan. There was a bare mattress on the floor but the woman who let her in put any anxieties she had at ease. The man told her she would be perfect for the role and it could be her lucky break - if she was brave enough to read the part without her clothes on. She did, and he proceeded to rape her. Ashamed, the actress did not report the rape to police, nor did she tell anyone else, keeping it a secret for 40 years. Murdered: Miss Cachay, 33, was found dead in a bathtub at the SoHo hotel on December 9 But the high-profile murder of Sylvie Cachay has forced her to relive it and has given her the strength to finally talk about it, especially after finding out about the other women. The married actress also decided to travel to New York and sit in on the younger Brooks' murder trial, hoping the experience would prove to be cathartic. 'I felt so guilty and shamed,' she told the New York Times last week in Manhattan District Court. 'To find out I wasn't alone, to find out that I wasn't just this stupid girl. I feel let out of prison. She however feels guilty that if she had reported the rape, she could have saved others from experiencing the same thing and maybe even have prevented the murder of Sylvie Cachay. 'If he is guilty and if he did do it,' she said of Nicholas Brooks, 'had I stopped the father, could I have stopped the son?' Surveillance footage recorded inside the exclusive SoHo House on December 9, 2010, shows 33-year-old designer Sylvie dressed in a coat and boots entering the building arm-in-arm with her two-timing boyfriend, Nicholas Brooks, just before 12.30am. Brooks, then 24-years-old, is seen in the CCTV footage carrying a pillow. The couple left Cachay's apartment earlier that evening after Brooks, a casual drug user, knocked over a candle and started a small fire, according to prosecutors. At 2.18am, cameras inside the hotel captured Brooks leaving his room for the last time and heading outside. By that point, prosecutors say Cachay had already been strangled and drowned in the bath tub. When she was found the next morning, her neck bore red marks and there was a bite mark on her hand. Scene: Jurors were shown pictures of this hotel room where Brooks allegedly strangled and drowned her Death chamber: The bath tub Sylvie's half-naked body was found submerged in at the Soho House hotel Pamela Guest, left, said of Nicholas Brooks: 'If he is guilty and if he did do it, had I stopped the father, could I have stopped the son?'Referring to the murder of Sylvie Cachay, right A lawyer for Miss Cachay's family said she was trying to break up with him, and prosecutors said that a letter found in her purse showed how Nicholas Brooks hadn't accepted that the relationship was over. If convicted, Nicholas Brooks could face up to life in prison. Joseph Brooks won the Academy Award for best original song for the 1977 Debby Boone ballad You Light Up My Life and directed a related movie. He also won a Grammy for the song. He pleaded not guilty in 2009 to rape, sexual abuse and other charges in the attacks on 13 women. Prosecutors say he lured most of the women to his apartment through an online ad offering auditions for a movie role, then sexually assaulted them after making them drink apparently drugged wine as part of an 'acting exercise'.
