Summary

A young woman (Mary McLeod) who rents a room in a London boarding house grows suspicious when she observes her landlord (John Abbott) using a pipe with a retractable needle -- the same type of needle being used in a series of unsolved murders. Little does she know that he has his own motives for carrying out what some say are cold-blooded killings. Lloyd Corrigan co-stars in this WWII-era suspense classic as a cop who looks into the case.
