Snowball by Jimmy Sangster

James Reed is an ex-Scotland Yard detective who became the bodyguard, then lover, then husband, then ex-husband of Hollywood superstar Katherine Long. Now he’s a self-styled beach bum, living in the Malibu beachhouse he got in the divorce settlement, and making a half-assed effort at screenwriting. But then Katherine comes back into his life —  her rebellious, spoiled daughter Caroline is mired in the Hollywood celebrity drug scene.  Katherine thinks James is the only one who can get his former step-daughter out before it beomes a scandal…or worse. The problem is, Caroline doesn’t want out, and his troubles snowball as James becomes an unwilling player in a $2 million scheme involving stolen drugs, high-powered studio execs, and ruthless mob killers
