Mike Schreck - another detective for our stable

In the episode of Broadway Is My Beat entitled "The Helen Carroll Murder Case," Sgt. Gino Tartaglia tells Lt. Danny Clover that during Clover's vacation he has been preparing himself by studying Schreck's methods. He is "the bald-headed miracle detective from Philadelphia." It seems that he developed two interesting theories: 1) Find the woman; and 2) The criminal always returns to the scene of the crime. He also supposedly coined the phrase "open and shut." Miracle detective he may be, but not very inventive.
