He later marries Carol Boynton.
Appointment with Death (1988 film)
In the 1988 film adaption of Appointment with Death, Cope is portrayed by David Soul. Here he has a larger role than in the book. He is the family lawyer of the Boyntons and is involved in other sideplots. At the beginning of the show, he informs Mrs Boynton that her husband Elmer Boynton had made a new will a few days before he died which divided the fortune between her and the children as opposed to leaving everything to her. Mrs Boynton tells Cope that she knows about his "share pushing" involving the Bolivian Silver Mining Corporation and intimidates him into burning the new will.
Subsequently, Cope trails the Boynton family in their tour of Europe, meeting up with them at Trieste. Unique to this adaptation, he is having an active affair with Nadine (in the original this is dormant until much later). Like in the original, Cope is an old flame of hers. They meet in Trieste and he gives her a cigarette case with an inscription as a gift.
Later, on board the ship to Jaffa, Mrs Boynton realises that Cope is a threat because he can talk about the new will and the fact that they had burnt it. During dinner, she tries to serve him a poisoned drink. This attempt fails because Lennox Boynton discovers the cigarette case and punches Cope on the face, causing him to spill his drink.
On arrival at Jaffa, he notices Miss Quinton and begins to take an interest in her. For the rest of the plot, his attention is divided between Miss Quinton and Nadine. He breaks off from the Boynton party to join Miss Quinton at Qumran. They were later reported as missing, although all they had done was take an excursion to the next valley and spend a night in a Bedouin camp.
When the Boynton family arrives at Qumran, Cope does join the Boynton children on a walk. Here, as in the original, he tries to persuade Nadine to leave Lennox to join him. However, Nadine later tells Poirot she was doing this just to stir Lennox into standing up for himself.
Unique to this adaptation, Cope pairs off with Miss Quinton at the end and not Carol Boynton.
