When Harman later tries to kiss Ruby she tells Hart who forces Ruby to blackmail Harman. When he refuses to pay off, Jeff tells Ruby to write a letter to Harmans sick wife, which causes her death from a heart attack. Dazed by the tragedy, Harman gives Ruby 300 pounds when she renews her demands. Jeff catches Ruby hiding part of the money, kills her and hides her body in a packing case. Harman discovers Rubys body and, thinking he will be accused, flees in panic. He enlists the help of his secretary Stella Chapman who helps him hunt for clues. When Stella stumbles on Hart alone she is nearly killed by him but Harman arrives in time to save her. The police arrest Hart.
