The Law & Harry McGraw
Harry McGraw was now a star in his own series, wherein he is still a private investigator in Boston. Who always seems to lose all of his money betting.
Harry's character was pretty well-established after his appearances on Murder, She Wrote. He was usually short of cash, drove a klunker, and often had to resort to using his young niece E.J. as his receptionist/research assistant. A lot of his money problems could be traced to his passions: pool, poker, ponies, the Red Sox, the Bruins, and a joint called Gilhooleys.
He was a good detective, though he wasn't above cutting corners (he once "kinda temporarily lost his license").
