To help Boulderstone recover from his brother's death, he is taken under the wing of those at 'Garden City'. Guy is enthusiastic about two new teachers he has employed. Boulderstone becomes a hero in a desert skirmish and is promoted to liaison officer. Harriet stays and sees Aiden Pratt, a young officer who was once a great actor in London. She thinks he is in love with her because he implores her and Guy to come and visit him in Damascus. Harriet contracts dysentery when she comes back from Luxor and has to stay in hospital for several weeks. Guy pays her little attention and continues rehearsing his newest play. Harriet decides to go back to England. Boulderstone is being driven to his new post when the Jeep stops at a WC and his driver is killed by a hidden mine. Boulderstone's legs are temporarily paralysed as a result. Harriet leaves Guy at the zoo to board the boat alone, but, at the last minute, sees Mortimer and begs her to take her to Damascus.
