Gabriel, for the most part, remained a spectator to her training. He greeted her when she arrived at the house each evening, joined the team for dinner, then saw her off again at midnight when she set out for London with Yossi. As the days wore on, they began to detect a restlessness in him. Lavon, who had worked with him more than the others, diagnosed Gabriel’s mood as impatience. “He wants to put her into play,” Lavon said, “but he knows she’s not ready.” He began spending extended periods before the canvas, painstakingly repairing the damage done to Marguerite. The intensity of the work only increased his restiveness. Lavon advised him to take breaks now and again, and Gabriel reluctantly agreed. He found a pair of Wellington boots in the mudroom and ventured out on solitary marches over the footpaths surrounding the village. He dug a rod and reel from a storage room in the cellar and used it to haul an enormous brown trout from the stock pond. In the barn, concealed beneath a tarpaulin, he found an ancient MG motorcar that looked as though it hadn’t been driven in twenty years. Three days later the others heard a sputtering sound emanating from the barn, followed by an explosion that reverberated over the countryside. Yaakov came running down from the house, fearful Gabriel had blown himself to bits, but instead found him standing over the open hood of the MG, covered in engine grease up to his elbows and smiling for the first time since they’d come to Surrey. “It works,” he shouted over the thunderous rattle of the motor. “The damned thing still runs.”

That evening he joined in Sarah’s training session for the first time. Lavon and Yaakov were not surprised, for the topic of discussion was none other that Ahmed bin Shafiq, the man who had become Gabriel’s personal bête noire. He chose Dina, with her pleasant voice and patina of early widowhood, to deliver the briefings. On the first night she lectured on Group 205, bin Shafiq’s secret unit within the GID, and showed how the combination of Wahhabi ideology and Saudi money had wreaked havoc across the Middle East and South Asia. On the second night she recounted bin Shafiq’s journey from loyal servant of the Saudi state to mastermind of the Brotherhood of Allah. Then she described in detail the operation against the Vatican, though she made no mention of the fact that Gabriel had been present at the scene of the crime. Gabriel realized that much of the information was superfluous, but he wanted Sarah to have no doubt in her mind that Ahmed bin Shafiq had earned the fate that awaited him.
