When he's drawn into a case, he combines sleuthing and medicine to solve the crime. That crime is usually one his detective son, Steve, is working on as a member of the local police department. Dr. Sloan's medical colleagues, including doctors Amanda Bentley, Jack Stewart and Jesse Travis, are also frequently drawn into his investigations.

Mark battles the Marines to get to the truth behind an apparent suicide outside Steve and Jesse's restaurant.

Mark competes on a popular television quiz show to find the final answer to a difficult question of life and death.

Mark's friend, singer Danielle Law, goes to him for help after being attacked by an unidentified man and eventually reveals a stunning secret.

Mark, deeply concerned about his son's new love interest and stuck home with a broken leg, takes to eyeing his neighbors through binoculars, a la Alfred Hitchcock's "Rear Window."
