This show ran from 1949 to 1954 and starred Ralph Bellamy as detective Mike Barnett.
He's a New York City cop and your typical tough, macho, no nonsense, charismatic character.
He's a very human character that doesn't make deductive leaps out of thin air.
He doesn't beat the truth out of people rather he simply keeps plodding along until he solves the case.
The dialog could have come straight from Raymond Chandler.
These are only half-hour episodes, so there isn't time for hugely complicated plot lines, but they're great little nuggets of crime thriller.

2. The Doll Bandit
3. Death takes a Partner
