The Killer

At Police House, Mitchell pulls a gun on Fowler and Beaumont telling them he is not the killer - he's only a smuggler. He tells them that he is just going to lock them in the station so he can escape when he is surprised by Chadwick who shots him. With the bullet lodged near his heart Doctor Lethbridge operates but to no avail. Before he dies, Mitchell reiterates that he is not the killer and tells Sergeant Fowler that Superintendant Chadwick is a fake - his name is Sanderson - he's never been a policeman in his life. That's why Sanderson shot him when he recognised him.Two more deaths have occurred as the bodies of Miss Reid and Doug Hemmings are found with shotgun blasts to the face.
