Night watchman Clyde Matik has been stabbed to death in an appliance store warehouse. One of the dead man's fellow employees is convinced that the guilty party is Matik's girlfriend Bessie Rowan (Ann Doran), but Friday (Jack Webb) and Smith (Ben Alexander) are sent off on a different path thanks to evidence dug up by the crime lab. The guilty party turns out to be a huge surprise for all concerned--especially Bessie Rowan. This episode is based on the Dragnet radio broadcast of August 16, 1955. ~ Hal Erickson, Rovi
