The sun was high by the time they came to the gateway of the castello.

Well, so far they have taken me where I wanted to go, Daoud thought grimly.

The entry hall of the castello was a large, vaulted room, as Daoud had expected. He had studied the citadel of Lucera before leaving Egypt, as he had studied many other strongholds in Italy, memorizing building plans and talking at length with agents of the sultan who had been there.

A strange, almost dizzying sensation came over Daoud. He recognized the feeling, having had it several times before when, in disguise, he entered Christian fortresses. As he gazed around the shadowy stone hall, its gloom relieved by shafts of light streaming in through high, narrow windows, he seemed to be seeing everything through two pairs of eyes. One pair belonged to a Mameluke warrior, Daoud ibn Abdallah, scouting an enemy stronghold. The other eyes were those of a boy named David Langmuir, to whom a Christian castle had been home. And, as always on sensing that inner division, Daoud felt a crushing sadness.

Ahmad took Daoud through a series of small, low-ceilinged rooms in the base of the castle. He spoke briefly to an officer seated at a table, dressed like himself in red turban and green tunic. He gestured to a heavy-looking door reinforced with strips of iron.

"In there, Messer David."

Every muscle in Daoud's body screamed out in protest. As part of his initiation into the Hashishiyya, he had been locked in a tiny black chamber in the Great Pyramid for days, and, except for the deaths of his mother and father, it was the worst memory of his life. Now he ached to strike down Ahmad and the other Muslim soldier and flee.

Instead, he said quietly, "How long will I have to wait?"

Ahmad shrugged. "God alone knows." Ahmad's southern Italian dialect was as heavily accented as Daoud's own.

How surprised he would be if I were to address him in Arabic.
