As you have already read by the person who has only seen this one film in the Boston Blacke series, they are not in the A budget class. Look a little closer and you'll see some up and coming actor, namely Forrest Tucker (Whipper). Who cares if it's not an A picture. These films are fun to watch! And by the way, the original writer of the Boston Blackie series was an opium addict and did time in prison. He began writing in prison and when he got out his stories were bought and changed for the movies. Columbia pictures had a hit on it's hands. Not all the movies made back then were Rita Hayworth and Glenn Ford, if it weren't for Boston Blackie and his antics Columbia would have probably gone bankrupt a long time ago. Most movies made even today aren't worth the time and money, but every now and then the movie makers get it right and it works. Open your mind and enjoy a fun film. Any Boston Blackie movie is fun to watch.
