She confided that my father and her husband had killed an important Roman general and that was why we had made haste to flee. She herself had cleaned the blades of their knives, washing the metal in pure water, reciting a prayer as she did. She was obliged not to ask questions, and to do as her husband demanded, but she had an urge to confess that she had handled a knife streaked with human blood, a confession made to me as we trudged after the men. Her voice broke as she spoke of it.

“How will God punish me?” she murmured.

I hushed her — women were not to speak of such matters — but it was too late. Ben Simon had overheard and turned to glare at us. He was a tall, imposing man, with dark olive skin, fearsome, a deep scar etched across one side of his face. Once again I gazed at the ground in an attempt to avoid him. He called sharply for Sia to be quiet.

WHEN WE could walk no farther, we stopped at a resting place, an oasis the assassins’ friends had spoken of in glowing terms. Every Zealot had a plan should disaster come, a direction in which he would run if need be. This was the first stop, a small green space where camels who had run off during the chaos had gathered. The beasts ran when we approached, kicking up dust, afraid that we would throw ropes around their necks, as unwilling to be slaves as we were. There was a citron tree growing there. The fruit of the tree is called pri etzhadar, the lemony etrog that is made into a jam.
