Jonny Stool Pidgeon (1949)

Minor B film noir about narcotics agent trying to expose drug smuggling ring with the help of convict (good role by Dan Dureya). Of course, by the very title of the movie, we can assume that Jonny Stool Pidgeon is in for a bad threat, from the moment he encounters narcotics agent in prison, and in brilliant scene where he enters into mortuary to find his son dead from a drug overdose. From that point things go downhill for Jonny, as the drug peddlers are closing in on them, sending cold-blooded killer to kill them. However, in some desperate attempt to save his soul Jonny Stool Pidgeon kills the hitman to save narcotics agent, but in the end he got killed instead. There is one particular memorable set piece when mobsters are digging a grave for Jonny only to realize it was their own hitman who must be burried. Someone may think if you watched a couple of these kind of movies you've seen them all, but it is in detail and and craftmanship that they never got old.
