He followed the circle counterclockwise and turned into Qasr el-Nil Street, Cairo’s version of the Champs-Élysées. He walked for a time, pausing now and again to gaze into the garish shop windows to see if he was being followed. He left Qasr el-Nil and entered a narrow side street. It was impossible to walk on the pavements because they were jammed with parked cars, so he walked in the street like a Cairene.

He came to the address shown on the business card Shamron had given him the night before his departure. It was an Italianate building with a facade the color of Nile mud. From a third-floor window came the strains of the BBC’s hourly news bulletin theme. A few feet from the entrance a vendor dispensed paper plates of spaghetti Bolognese from an aluminum cart. Next to the vendor a veiled woman sold limes and loaves of flat bread. Across the cluttered street was a kiosk. Standing in the shade of the little roof, wearing sunglasses and a Members Only windbreaker, was a poorly concealed Mukhabarat surveillance man, who watched as Gabriel went inside.

It was cool and dark in the foyer. An emaciated Egyptian cat with hollow eyes and enormous ears hissed at him from the shadows, then disappeared through a hole in the wall. A Nubian doorman in a lemon-colored galabia and white turban sat motionless in a wooden chair. He lifted an enormous ebony hand to receive the business card of the man Gabriel wished to see.

“Third floor,” he said in English.

Two doors greeted Gabriel on the landing. Next to the door on the right was a brass plaque that read: DAVID QUINNELL—INTERNATIONAL PRESS. Gabriel pressed the bell and was promptly admitted into a small antechamber by a Sudanese office boy, whom Gabriel addressed in measured German-accented English.

“Who shall I say is calling?” the Sudanese replied.

“My name is Johannes Klemp.”

“Is Mr. Quinnell expecting you?”

“I’m a friend of Rudolf Heller. He’ll understand.”

“Just a moment. I’ll see if Mr. Quinnell can see you now.”

The Sudanese disappeared through a set of tall double doors. A moment turned to two, then three. Gabriel wandered to the window and peered into the street. A waiter from the coffeehouse on the corner was presenting the Mukhabarat man with a glass of tea on a small silver tray. Gabriel heard the Sudanese behind him and turned round. “Mr. Quinnell will see you now.”

The room into which Gabriel was shown had the air of a Roman parlor gone to seed. The wood floor was rough for want of polish; the crown molding was nearly invisible beneath a dense layer of dust and grit. Two of the four walls were given over to bookshelves lined with an impressive collection of works dealing with the history of the Middle East and Islam. The large wood desk was buried beneath piles of yellowed newspapers and unread post.
