Doctor Hook is the surgeon who performs a lifesaving operation on artist Peter Rickman.

He secretly keeps a log of gross malpractice and other violations by Kingdom Hospital doctors.

Hook lives in a basement apartment at Kingdom Hospital, stuffed with all kinds of hospital equipment he has salvaged or acquired by swapping and dealing on the side. Despite his quirks, he has a good bedside manner and is forthright and honest with his patients and their families.
