The one and only Frank Cannon.
A Quinn Martin Production.
Guest starring an assortment of people.
Or as Benny Hill would say, 'A Quinn Martin, Harton, Barton and Fargo Production.'
I remember Mahtin Sheen. It was weird that he played an old cop buddy of Cannons on a pair of episodes and later appeared as a murderer. They did that a lot back then but wouldnt get away with it on modern shows.
