Dr Death has been brutally murdered and Dr Delaware must find out why . . .
When Eldon Mate, medical bureaucrat turned self-proclaimed mercy killer is the victim of a grisly Hollywood Hills slaying - hooked up to the macabre "Humanitron" with which he has despatched dozens of people - veteran LA cop Milo Sturgis is assigned to the case. Baffled, Milo consults his friend, psychologist Alex Delaware, who realises quickly that lack of suspects isn't the problem - there is an abundance of individuals who might have wished the controversial Mate dead.
At the same time, Alex Delaware must walk an ethical tightrope, when his own professional past comes back to haunt him, and he is torn between helping his friend and safeguarding the darkest secrets of his patients. Pressured and in conflict as never before, Delaware finds himself caught in the middle of his most complex and terrifying case.
