“At one time, the harem housed more than a thousand concubines, slaves, sultan’s wives, and the sultan’s mother. The harem was like a small city, with more than four hundred rooms. On your left are the quarters of the Black Eunuchs and the chief eunuch, who guarded the harem. Other doors lead to the quarters of the imperial treasurer and the chamberlain. You can go through that door and inspect the apartments of the eunuchs,” he said.

The guide gave the same speech in Turkish, and then led the way into the guards’ dormitory like the Pied Piper of Hamelin.

Austin held Carina back until they were alone in the courtyard. His blue-green eyes scanned the doors, searching for a possible escape route. He tried one door handle. The door was unlocked. He was hoping they could lose their pursuers in the vast labyrinth of apartments and courtyards.

“Kurt,” Carina said.

The Carriage Gate door had opened. Buck stepped into the courtyard with his hard-faced friends and signaled to his men to spread out. They moved three abreast toward their prey.

The guide and the tour group poured out of the eunuchs’ living quarters into the courtyard, creating a human barrier of camera-toting tourists. Austin and Carina merged with the group as it went through a door that stood in a vestibule at the far end of the courtyard.

Austin glanced over his shoulder. Buck and his men were shouldering their way through the crowd.

“What should we do?” Carina whispered.

“Enjoy the tour for now, and when I say run, run.”

“Run where?”

“Still working on that,” Austin said.

Carina muttered in Italian. Austin didn’t need a translator to tell him she was cursing. He saw her anger as a good sign that she hadn’t given in to despair.

The guide led the way through a square-domed chamber. Stopping every few minutes to deliver a speech in Turkish and in English, the guide pointed out where the concubines lived, where the children of the harem went to school, and where the food for the vast complex was prepared.

Austin glanced longingly at the doors and corridors that offered possible escape routes. There was no way he and Carina could break away from the crowd. With each stop, Buck and his friends drew closer.

Austin put himself in the shoes of the pursuers. The three men would move in and separate him from the crowd. Two men would finish him off with their knives. The third would grab Carina.

Buck and his thugs were all former special ops men. Their training would have included knife fighting and assassination. A hand clamped over his mouth to prevent him from calling out. A quick thrust of a blade between his ribs. By the time bystanders realized murder had been done, Austin would be breathing his last. Buck and company would slip away in the confusion that would follow.
