Meanwhile, Albert and the others remain distrustful of the Briton. Monique tails him to France in order to ascertain whether Curtis is genuine. Curtis comes to believe that Hugh Neville is responsible for Victor's death and Romsey's capture. Posing as a downed Yorkshireman flyer, he visits the Neville's home and fatally stabs Hugh Neville.
