Wallender nodded and smiled.

“Welcome,” the officer murmured, in English. “For what do you come to Gaza?”

“I’m with the United Nations Relief and Works Agency, in the Jerusalem office,” Wallender said. “We’re making an inspection of the UN schools in the Gaza refugee camps.” He gestured toward Omar Yussef. “My colleague is the principal at one of our schools in Bethlehem.”

The officer nodded, though Omar Yussef was sure the man’s English wasn’t equal to Wallender’s explanation. Omar Yussef noticed that he transcribed the Swede’s name incorrectly in the large, dog-eared tablet on the table.

“How long since you were in Gaza, ustaz?” the officer asked Omar Yussef.

“Twenty years, my son. The permit isn’t easy to get.”

“You’ll notice some changes in Gaza.”

“Gaza will notice some changes in me.” Omar Yussef gave a short laugh that sounded as though he were preparing to expectorate. “When I was last in Gaza, I had nice curly hair and I could carry an overnight case without breaking into a sweat.”

The officer grinned. He glanced from the ID card to Omar Yussef and his smile wavered, betraying polite confusion. Is he surprised that I’m not as old as I look? Omar Yussef thought. Just below average height, Omar Yussef appeared even shorter because his shoulders stooped like those of an old man. His hair was white, liver spots stained his balding scalp, and his tidy mustache was gray.

“At least, you still have your mind, uncle.” The officer handed back the ID card. “Unlike Gaza.”
