The Lucifer Connection — David Watts

Jack Barnstone is an outside-the-box, motorcycle-riding physician who, finding himself in two kinds of trouble, leaves Texas to start a solo practice near Chinatown in San Francisco. When a patient walks in his office with an undiagnosed mortal illness Barnstone's life changes forever. Finding himself in deeper trouble than ever he must work his way through a malpractice suit, the mistrust of his colleagues and the suspicions of the San Francisco police in order to vindicate himself. Since he has arrived in San Francisco just at the start of the Summer of Love to pursue his quest he has to learn the inner workings of Hippie culture, the sinister workings of the Satanic Church while he is dodging the unpredictable actions of the San Francisco Police. With help from his new Hippie girlfriend and an old flagrantly gay East Indian assistant coroner he discovers why the case was so difficult to solve, confronts the perpetrator and stumbles upon a well-hidden and sinister web of criminal activity.
