Ivy Bishop is the pretty, young English girl whom Ashenden is introduced to after he meets McLeod. Since she has been in and out of sanatoriums for nearly 10 years, Ivy looks much younger than she actually is. Ashenden is told by McLeod the day they first meet that he believes there is a relationship between Ivy and Templeton. As Ashenden watches the two together and notices the soft look on Ivy's face as she smiles at Templeton, he agrees with McLeod's observation. Although she knows that her new husband will not live very long, Ivy still agrees to marry Templeton when he asks her. Ivy agrees that when Templeton dies, she will return to the sanatorium.
