The scientist and the VAVAK guy returned after a few minutes, and Ben followed them to Hagia Sophia, waiting near the exit again while they were inside. Their next stop was Topkapi Palace, and this time one of the VAVAK guys waited outside. This confirmed for Ben what he already strongly suspected: the VAVAK guys were armed. Topkapi was home to a priceless collection of jewel-encrusted Ottoman swords and crowns and thrones, and there was a metal detector at the entrance to prevent anyone from bringing in hardware for a robbery. Ben figured the guy who was waiting was holding both their guns while the other accompanied the scientists inside. He was half tempted to hide the Glock somewhere and follow them in, but dropping all three barehanded would have presented something of a challenge. Not to mention all the cameras, the single point of egress, and the guards with submachine guns. No, there would be a better opportunity. He waited outside the massive palace gates, haggling with merchants, shooting a few photos, occasionally sneaking a peek through the entrance to make sure the VAVAK guy was still there. He watched the people coming and going carefully in case there was a countersurveillance unit involved. The intel hadn't mentioned it, but intel was never perfect and you had to be careful. He didn't see anything that rubbed him the wrong way.
After Topkapi, the Iranians headed west through the gathering dusk. Ben thought he knew where they were going: either the Grand Bazaar or the Spice Bazaar. If he was right, his opportunity was coming.
They wandered down narrow cobblestone streets through alternating pools of darkness and light, the sound of their footsteps echoing on the stone walls to either side and mingling with the conversation and laughter of shoppers and passersby What sky was visible was a dull, dying gray. The rain had stopped, but it was still humid and cold, and a sheen of perspiration gleamed on the peeling façades of souvenir shops and carpet stores and food stalls, all crammed side by side under sagging awnings and rusted escarpments. Ben kept well back, pausing when the Iranians paused, moving when they moved, staying cool, staying patient, knowing something would open up.
The sounds around them were suddenly drowned out by the evening muezzin chanting out the adhan, the call to prayer. Ben's Arabic wasn't as strong as his Farsi, but he understood the words:
God is greatest. I bear witness that there is no lord except God. I bear witness that Mohammed is the messenger of God. Make haste toward prayer. Make haste toward welfare. God is greatest. There is no lord except God.
The Iranians stopped at a small, undistinguished corner building recognizable as a mosque only from the minaret near its entrance. The scientists took off their shoes and went inside, accompanied by one of the VAVAK guys. The other waited outside. Ben smiled. Maybe they were willing to put their faith in God, but not their security. He hung back and waited.
Fifteen minutes later, they emerged and continued northwest. Come on, Ben thought. The Spice Bazaar. You know you want to.
They moved along Marpuccular Cad, the road that provided the southwest boundary of the bazaar, then onto Tahtakale Cad, still moving northwest. They paused from time to time to examine the wares of the various shops, but didn't go inside. The VAVAK guys maintained their tactical positions. Come on, Ben thought. Come on. Despite the cold he could feel himself perspiring.
He followed them right onto Uzunçarşi Cad, his breath starting to quicken slightly. It was full dark now. He'd been afraid they were going directly to the Galata Bridge, but now it looked good, it looked like it was the Spice Bazaar after all. He tightened the cords on the backpack and squeezed his left arm against the satisfying bulk of the holstered Glock.
He stayed with them until they turned right onto Hasircilar Cad, the main street of the Spice Bazaar. All right. This was what he'd been waiting for.
He turned and dashed down the middle of Tahtakale Cad, paralleling the route the Iranians were now on, dodging cars and trucks, staying off the sidewalks to avoid the thick clots of pedestrians. The backpack was secure. The weight of the Glock felt right.
He cut left on Yeni Cami Cad, then left again on Çiçek Pazari Sok, now on a collision course with the Iranians. The jostling crowds were thick and he had to slow. He passed stalls filled with enormous mounds of spices, their yellows and oranges and reds and greens impossibly bright under the incandescent bulbs strung up above them. Tables were piled high with candies and honey-soaked pastries and fruit. The air was thick with the mingled aromas of spices and coffee and tobacco smoke. Peddlers cried out warnings above the din as they maneuvered pushcarts around clusters of shifting shoppers.
At the corner of Tahmis Cad and Hasircilar Cad he could see them coming toward him, about forty feet away. His heart was beating hard now. He checked his perimeter and sensed nothing amiss.
He moved left, pausing in front of one of the corner windows of Kurukahveci Mehmet Efendi, one of the city's oldest coffee shops. Ben had been here a half dozen times during reconnaissance, and there were always at least ten people lined up at its two corner windows waiting to buy quantities of the house-roasted beans. It was a logical stop for the Iranians. Even if they didn't stop here, though, they were going to pass right by. He would be able to see them through the store's windows.
He moved back, pretending to examine the colorful cookware in the stall adjacent to the coffee shop. He pulled the hat down low and unzipped his jacket. His heart was hammering.
A minute later, the first VAVAK guy appeared through the adjoining corner window. He made a right and stopped not ten feet from where Ben stood. The scientists were in front of the adjoining window now, lined up with a dozen other people to purchase some of Kurukahveci's famed beans. He couldn't see the second VAVAK guy, but it was a safe bet he was somewhere a short distance behind them.
Ben closed his eyes for a moment and took a deep breath, then let it out. Another. And again.
He pulled a guidebook from one of his pockets and slowly walked past the VAVAK guy while examining it. He didn't consider what he was about to do. He focused on the book.
At the corner in front of the coffee shop, he looked left. There was the second VAVAK guy, as he had expected, behind the scientists, twenty feet away.
He looked straight, then right, just another addled tourist trying to orient himself. He detected no problems.
He dropped the guidebook back in his pocket and headed back to the first VAVAK guy. He walked past his position without looking directly at him. He saw in his peripheral vision that the VAVAK guy was watching him now. It didn't matter. It was too late.
He passed by the VAVAK guy's left side. As he did, he let his right hand drift inside his open jacket. By the time he was three steps past the VAVAK guy, the Glock was out. He pivoted counterclockwise, stepping through with his right foot, and brought up the Glock from five feet away.
The VAVAK guy had just enough time to widen his eyes. Ben pressed the trigger. There was a quiet pffft and a neat black hole appeared in the VAVAK guy's forehead. His head jerked and a spasm passed through his body. Then his knees buckled and he slid to the ground. Ben was already moving past him. He rounded the corner.
The scientists were at the window now. The second VAVAK guy saw Ben moving past them, the Glock at his side, approaching with unmistakable intent. Someone from around the corner screamed.
