A young Canadian couple, honeymooning at a neighbouring hotel, had noticed the commotion and heard Madame Malot’s stifled cries, but could not see what was happening in the light of the waning moon. By the time they got there, the men who had attacked and murdered the elderly French couple had vanished into the night, leaving a scene of devastation that the Egyptian authorities quickly dismissed as a random act of violence, perpetrated by outsiders, which was ‘highly unlikely ever to happen again’.

Taking someone in the street is as easy as lighting a cigarette, they had told him, and as Akim Errachidi waited in the van, he knew that he had the balls to pull it off.

It was a Monday night in late July. The target had been given a nickname – HOLST – and its movements monitored for fourteen days. Phone, email, bedroom, car: the team had everything covered. Akim had to hand it to the guys in charge – they were thorough and determined; they had thought through every detail. He was dealing with pros now and, yes, you really could tell the difference.

Beside him, in the driver’s seat of the van, Slimane Nassah was tapping his fingers in time to some R&B on RFM and talking, in vivid detail, about what he wanted to do to Beyoncé Knowles.

‘What an ass, man. Just give me five minutes with that sweet ass.’ He made the shape of it with his hands, brought it down towards his circling groin. Akim laughed.

‘Turn that shit off,’ said the boss, crouched by the side door and ready to spring. Slimane switched off the radio. ‘HOLST in sight. Thirty seconds.’

It was just as they had said it would be. The dark street, a well-known short-cut, most of Paris in bed. Akim saw the target on the opposite side of the street, about to cross at the postbox.

‘Ten seconds.’ The boss at his very best. ‘Remember, nobody is going to hurt anybody.’

The trick, Akim knew, was to move as quickly as possible, making the minimum amount of noise. In the movies, it was always the opposite way: the smash-and-grab of a screaming, adrenalized SWAT team crashing through walls, lobbing stun grenades, shouldering jet-black assault rifles. Not us, said the boss. We do it quiet and we do it slick. We open the door, we get behind HOLST, we make sure nobody sees.

‘Five seconds.’

On the radio, Akim heard the woman saying ‘Clear’ which meant that there were no civilians within sighting distance of the van.

‘OK. We go.’

There was a kind of choreographed beauty to it. As HOLST strolled past Akim’s door, three things happened simultaneously: Slimane started the engine; Akim stepped out into the street; and the boss slid open the side panel of the van. If the target knew what was happening, there was no indication of it. Akim wrapped his left arm around HOLST’s neck, smothered the gaping mouth with his hand and, with his right arm, lifted the body up into the van. The boss did the rest, grabbing at the legs and pulling them inside. Akim then came in behind them, sliding the door shut, just as he had rehearsed a dozen times. They pushed the prisoner to the floor. He heard the boss say: ‘Go’, as calm and controlled as a man buying a ticket for a train, and Slimane pulled the van out into the street.

The whole thing had taken less than twenty seconds.

Thomas Kell woke up in a strange bed, in a strange house, in a city with which he was all too familiar. It was eleven o’clock on an August morning in the eighth month of his enforced retirement from the Secret Intelligence Service. He was a forty-two-year-old man, estranged from his forty-three-year-old wife, with a hangover comparable in range and intensity to the reproduction Jackson Pollock hanging on the wall of his temporary bedroom.

Where the hell was he? Kell had unreliable memories of a fortieth birthday party in Kensington, of a crowded cab to a bar in Dean Street, of a nightclub in the wilds of Hackney – after that, everything was a blank.

He pulled back the duvet. He saw that he had fallen asleep in his clothes. Toys and magazines were piled up in one corner of the room. He climbed to his feet, searched in vain for a glass of water and opened the curtains. His mouth was dry, his head tight as a compress as he adjusted to the light.

It was a grey morning, shiftless and damp. He appeared to be on the first floor of a semi-detached house of indetermin-ate location in a quiet residential street. A small pink bicycle was secured in the drive by a loop of black cable, thick as a python. A hundred metres away, a learner driver with Jackie’s School of Motoring had stalled midway through a three-point turn. Kell closed the curtains and listened for signs of life in the house. Slowly, like a half-remembered anecdote, fragments of the previous evening began to assemble in his mind. There had been trays of shots: absinthe and tequila. There had been dancing in a low-roofed basement. He had met a large group of Czech foreign students and talked at length about Mad Men and Don Draper. Kell was fairly sure that at a certain point he had shared a cab with an enormous man named Zoltan. Alcoholic blackouts had been a regular feature of his youth, but it had been many years since he had woken up with next to no recollection of a night’s events; twenty years in the secret world had taught him the advantage of being the last man standing.

Kell was looking around for his trousers when his mobile phone began to ring. The number had been withheld.

‘Tom?’

At first, through the fog of his hangover, Kell failed to recognize the voice. Then the familiar cadence came back to him.

‘Jimmy? Christ.’

Jimmy Marquand was a former colleague of Kell’s, now one of the high priests of SIS. His was the last hand Kell had shaken before taking his leave of Vauxhall Cross on a crisp December morning eight months earlier.

‘We have a problem.’

‘No small talk?’ Kell said. ‘Don’t want to know how life is treating me in the private sector?’

‘This is serious, Tom. I’ve walked half a mile to a phone box in Lambeth so the call won’t be scooped. I need your help.’

‘Personal or professional?’ Kell located his trousers beneath a blanket on the back of a chair.

‘We’ve lost the Chief.’

That stopped him. Kell reached out and put a hand against a wall in the bedroom. Suddenly he was as sober and clear-headed as a child.

‘You’ve what?’

‘Vanished. Five days ago. Nobody has any workable idea where the hell she’s gone or what’s happened to her.’

‘She?’ The anti-Rimington brigade within MI6 had long been allergic to the notion of a female Chief. It was almost beyond belief that the all-male inmates at Vauxhall Cross had finally allowed a woman to be appointed to the most prestigious position in British Intelligence. ‘When did that happen?’

‘There’s a lot you don’t know,’ Marquand replied. ‘A lot that’s changed. I can’t say any more if we’re talking like this.’

Then why are we talking at all? Kell thought. Do they want me to come back after everything that happened? Have Kabul and Yassin just been brushed under the carpet? ‘I’m not working for George Truscott,’ he said, saving Marquand the effort of asking the question. ‘I’m not coming back if Haynes still has his hands on the tiller.’

‘Just for this,’ Marquand replied.

‘For nothing.’

It was almost the truth. Then Kell found himself saying: ‘I’m beginning to enjoy having nothing to do,’ which was an outright lie. There was a noise on the other end of the line that might have been the extinguishing of Marquand’s hopes.

‘Tom, it’s important. We need a re-tread, somebody who knows the ropes. You’re the only one we can trust.’
