One Dangerous Night [1943] [DVD]

Lanyard and his butler Jamison are driving off to a party when they come across Eve (Marguerite Chapman) whose car has gotten a few flats. They deliver her to a home and continue on - only for Jamison to gleefully confess that he stole her purse. They go back to give it to her but instead find a dead body in the house. And the police find them. The hunt is on with a group of women who were being blackmailed by the dead man and were all in the house when the lights went off. And there is also Ann Savage as part of a gang who has a history with Lanyard and a loaded gun on him now.

A lively entry finds our hero getting involved in blackmail and murder, which is par for the course for the Lone Wolf, which is played by Warren William with his raffishness. There's the usual twist and turns and some good action. ~ imdb
