The Invisible Fear on AllMovie

Popular silent star Anita Stewart wasn't immune to appearing in routine program pictures, and this mystery has little to recommend it other than her presence. The lusty Arthur Comstock (Walter McGrail) tries to force himself on lovely Sylvia Langdon (Stewart). In an attempt to escape his unwanted advances, Sylvia hurls a candlestick at him, knocking him senseless. She sees his prostrate form through a window and is convinced she has killed him. She marries her fiancé, Bentley Arnold (Allan Forrest), and tries to forget the incident. But she's in for a shock when she and Arnold throw a party at their home and Comstock shows up. Sylvia dashes out of the room in shock and Comstock follows after her. Instead of demanding her body, however, he demands that she give him the family jewels. Comstock, it turns out, murdered his uncle, and it was his body that Sylvia had seen through the window. Comstock's attempts at thievery are foiled and he gets his due.
