I loved "Quincy, M.E." Jack Klugman, with that raspy voice and air of authority. And the show's mysteries were always fascinating, and you forgot that they involved dead bodies being cut up and pushed around.
I love this summary, from Wikipedia:
"Many of the episodes follow a set formula:
Somebody dies, seemingly by natural causes.
Quincy notices something that causes him to suspect foul play.
He then changes roles from medical examiner to detective, by refusing to release the body and sign off on the cause of death, to Dr. Asten's disapproval.
Asten gets upset, believing Quincy is seeing evidence that doesn't exist, and urges the doctor to speedily conclude his investigations and accept the obvious. Lt. Monahan's feathers are ruffled too as Quincy "shoulders-in" on police territory.
Quincy argues quite loudly with some bureaucratic individual impeding the case.
Quincy solves the murder."
I also loved the intro, where you think Quince is examining a corpse but it's really a hot babe on his boat. And when he is examining a corpse, all the cops watching faint.
