As Goren absorbed this, his anger with Davenport growing by the second, McAllister was still shouting angrily: "Seventeen stitches in your leg, plus one month whilst the doctors try to decide if your leg muscles will ever work properly again, months of physio, and a near-permanent inability to trust men, is not "just fine" by anyone's standards, Drew!"

"People heal."

"Sienna hasn't."

"That's not my problem. And by the way, she does actually have a mind of her own. It was her decision to apply for the job, her decision to move here."

"You really are incorrigible, aren't you?" McAllister shook his head tiredly, and looked at the ground. Part of Goren's mind, the part that never quite stopped working, wondered coolly how long McAllister had suspected, thinking he staged that, wanted to be sure I'd overhear… But most of his mind was consumed by anger, anger at the man who had taken Sienna from him.

"I'm who I always have been. I screw people over in the service of my country. There are times when history needs heroes. Unfortunately?" Davenport's voice was tired. "Right now is one of those times when what it actually needs are complete bastards like me. Durham was responsible for God knows how many women being trafficked into this country. I needed to catch him, and unfortunately that was the only way."

"What right did you have to do that to her?" He was furious now, Davenport's apparent indifference stoking the fury. He would keep his cool, he tried to think, tried to stay calm, but part of his mind was increasingly shouting, that bastard! How did he dare to do that to her? To me

"It wasn't a matter of having the right, or of doing anything to her. I made a few suggestions, she agreed with them."

"You used her as bait."

"That's right, I did. And it worked. Durham went down, SiSi's new career got off to a flying start, I got the result. Win-win all round."

"You had no right to do that." He stalked forwards, pressing the spy back against the wall. He was taller than Davenport, and more heavily built, and right now he intended to scare the life out of the man.

Davenport sighed, and met his eyes for the first time. His gaze was not afraid, but oddly angry, almost as if he was furious with Goren. "That's actually quite amusing, coming from the man who didn't even bother to come to the airport to wave her goodbye after they'd lived together for months. Yes, I know about that; I was there, on the same flight. Eight hours she spent crying on that plane because of you, Goren. And by the way, quit with the physical intimidation crap, it doesn't work. I'm in better shape than you, and every so often I go up against people who would pull out my fingernails with pliers if they caught me."

"Whatever I did or didn't do, you had no right to do that." He was shaken, and knew that it must be obvious to anyone watching. Davenport slipped to the side, muscles tense, ready to defend himself.

"Goren, did you know that even when Sienna…" Davenport suddenly broke off, paused, then continued: "…talks about other men with her friends, she always compares them to you? Well, she does." He leaned forward, and they locked gazes, the air burning between them. Davenport glowered at him, then turned suddenly and walked away a few paces. His back to Goren, he continued: "You talk about me doing something to Sienna, but you know what?"

He spun on the spot, and his face was no longer angry, just tired. "I can't force people to believe things, or do things. I can only make suggestions – persuasive suggestions, okay, but I can't force them to believe things." He sighed heavily. "Shout at me all you like, but you know that as well as I do. If Sienna had believed for one minute that you and she had a future, that you'd live together, get married, all that stuff… I couldn't have pried her away from you with a crowbar."

"Maybe not, but you sure as fuck could have told me why you wanted me to move over here." Sienna's voice coming from behind surprised both of them. Clad incongruously in her clothes for the gym, hair tied back, she glowered across the rooftop at both of them, angry and hurt. Goren was struck by a sudden desperate urge to comfort her.

"It's so flattering, the way both of you assume I have no mind of my own," she continued, bitterly angry and sarcastic. Goren could see the unshed tears of betrayal in her eyes, and wasn't sure if they were for him or for the friendship she thought she'd had with Davenport, or both.

"Jesus Christ, Drew…" She shook her head. "You never told me you knew Durham was corrupt from the beginning. Not once, not in two years."

Davenport opened his mouth, but she didn't let him finish. "Don't tell me, let me guess. I was too young, too naïve to play the role of besotted young female idiot convincingly if I actually knew I was supposed to be playing a role. So much more convincingly if I actually had fallen for him before he asked me to get involved, and then of course you asked me to act as bait…"

Davenport spread his hands. He looked genuinely saddened. "SiSi… would you believe me if I said I was sorry about how that turned out?"

Sienna met his gaze with angry eyes. He didn't flinch. "No, Drew. I wouldn't. You've had two years to tell me the truth. Fucking hell. All this time, were you laughing at me?" She was nearly crying. "All this time… you knew. You planned this."

"I did what I had to do to get the result. I never intended that you'd get shot."

Sienna's expression was anguished. "You were never my friend, Drew, were you?" She was crying now.

"SiSi…" Davenport opened his mouth again, then, closed it. He spread his hands, shaking his head, mute, as if he had finally run out of words.

Dropping his head, he simply walked quietly off the roof, not saying another word. They watched him leave. Tanya and Eames, who'd heard the shouting and come to investigate, silently stepped aside. Tanya's expression was shocked and grim in equal measures. She had obviously overheard much of the conversation. How painful it must be for her, he thought numbly, to know that her oldest friend betrayed her closest friend.

Sienna turned to Goren, and he held out his hand, ignoring the other people on the roof. She shook her head. "Bobby, I'm sorry… I can't do this now. I'll call you tomorrow. I'm sorry." She turned and left. Tanya heaved a massive sigh, then turned and went after her.

Goren and Eames met each other's gaze.

"Bobby, let's get back to the hotel," she said in a subdued voice.

"Yeah." His head in turmoil, he followed his partner downstairs.

Later that night, he sat alone in his room, sipping methodically at a glass of whisky from the minibar, staring out of the window at the traffic rolling by.

Sienna… He understood the truth now. More painfully, he knew that in many ways, Davenport had been right. He could blame the man all he liked for persuading Sienna to leave him, but the bottom line was that Sienna had chosen to leave of her own free will, and she had done so because he had never given her any reason to believe that they had a future together.

Just then, the phone in his room rang. He debated whether to answer it, then took a deep breath and picked it up.

"Bobby?" It was Sienna's voice. She sounded calm and under control, but as though she'd been crying.

"Hi."

"I want to talk to you. Can you meet me at the Anchor pub, on the South Bank, tomorrow at five? It's not difficult to find."

"Would you like to come over here now?" He wished desperately just to see her. He wanted to hold her. Perhaps more than that, he wanted to hear her voice, to listen to her, to help her talk through what had happened.

"Oh, Bobby," Her tone was soft, almost longing, but also desperately sad, and he knew the answer before she gave it. "I can't. Not right now. I need space."

"Where are you?" He suddenly wanted to be sure that she was safe.

"In my apartment. I needed some time alone." Her tone changed, becoming more desperate. "Please… Please can you see me tomorrow?"

"Okay… okay. Yes. I will."

She sighed. "I'm afraid we won't have long… I'm working and I promised Uncle Peter I'd meet him for dinner. Are you going to be at the match on Saturday?"

"I can be." He remembered Eames telling him that they could probably get tickets.

"Well… could you be? I'll have to be in the VIP box most of the time, but I can sneak out of there and we can meet up at half-time, or maybe have a drink afterwards. I'll tell Uncle Peter I have to be somewhere else. I want to talk to you properly." Her voice broke. "I've missed you so much…" She pulled herself together. "I'm sorry. Now isn't the time."

"Tomorrow, then," he said, awkwardly, then added. "I missed you, too. So much."
