An Unseen Enemy

The physician's death orphans his two adolescent daughters. Their older brother is able to convert some of the doctor's small estate to cash. But it is late in the day, and with the banks closed he stores the money in his father's household safe. The slatternly housekeeper, aware of the money, enlists a criminal acquaintance to crack the safe. She attempts to get into the adjacent room where the sisters tremble in fear, but finds that the door is locked. The drunken housekeeper menaces them by brandishing a gun through a hole in the wall.
