The smaller of the two men went onto the terrace while the other man smoked. A black storm was pushing up Clifden Bay, and the wind felt as though it were filled with shrapnel. Five minutes was all he could stand. Then he went back inside, into the smoke and the tension of the wait. He felt no shame. Even the gulls did not stay on the terrace for long.

Throughout his long career, Gabriel had had the misfortune of meeting many terrorists: Palestinian terrorists, Egyptian terrorists, Saudi terrorists, terrorists motivated by faith, terrorists motivated by loss, terrorists who had been born in the worst slums of the Arab world, terrorists who had been raised in the material comfort of the West. Oftentimes, he imagined what these men might have achieved had they chosen another path. Many were highly intelligent, and in their unforgiving eyes he saw lifesaving cures never found, software never devised, music never composed, and poems never written. Liam Walsh, however, made no such impression. Walsh was a killer without remorse or proper education who had no ambition in life other than the destruction of life and property. In his case a career in terrorism, even by the reduced standards of the diehard Irish republicans, was about the best he could have hoped for.

He was without physical fear, however, and possessed a natural obduracy that made him difficult to break. For the first forty-eight hours he was left in total isolation in the damp chill of the cellar, blindfolded, gagged, deafened by earplugs, immobilized by duct tape. He was offered no food, only water, which he refused. Keller saw to his bathroom needs, which were minimal given his dietary restrictions. When necessary, he addressed Walsh in the accent of a Protestant of the working classes from East Belfast. The Irishman was offered no way out of his predicament, and he did not ask for one. Having seen three of his mates killed in the blink of an eye, he seemed resigned to his fate. Like the SAS, Irish terrorists and drug gangsters played by big boys’ rules.

On the morning of the third day, maddened by thirst, he partook of a few ounces of room-temperature water. At midday he drank tea with milk and sugar, and in the evening he was given more tea and a single slice of toasted bread. It was then that Keller addressed him for the first time at any length. “You’re in a shitload of trouble, Liam,” he said in his East Belfast accent. “And the only way out is to tell me what I want to know.”

“Who are you?” asked Walsh through the pain of his broken jaw.

“That depends entirely on you,” replied Keller. “If you talk to me, I’ll be your best friend in the world. If you don’t, you’re going to end up like your three friends.”

“What do you want to know?”

“Omagh,” was all Keller said.
