Khan began to flag after another hundred metres. Henry started to gain, although he was tiring and regretting his overindulgence at breakfast.
But Khan had nowhere to go. He eventually sagged down on to his knees, as though his batteries were running out, then slumped on to all fours and puked.
Henry skittered up behind him in the gravel, panting, âYou â¦are ⦠under ⦠arrest ⦠onsuspicionofmurder.' He emitted the last four words as one.
Even though the complication of Henry being a detective from Lancashire operating without the knowledge or blessing of the locals was quickly dealt with, his prisoner was not. After pinning Khan down and dragging him back to the north gate, Henry had called 999 on his mobile and waited patiently for the promised response, which took about twenty minutes.
The circumstances took another ten minutes to explain to the two PCs who arrived in a Transit van and then conveyed him to the police station on Fulham Road, via Starbucks where he collected his briefcase and made his apologies. Unsurprisingly, Aysha had disappeared.
Booking the prisoner in took an interminable length of time.
Southwest London must have had a busy morning. Henry was told he had to remain with his prisoner until the booking-in was done. He wasn't required to remain physically by the side of Khan, but was instructed to stay in the custody area. Khan was put into a holding cage with six other prisoners who all looked like serious armed robbers.
Henry paced the cell corridor, straightening his thoughts, wondering what the best course of action would be.
As ever, he decided to wing it.
âDCI Henry Christie, Lancashire Constabulary,' he introduced himself to the Met custody sergeant. He pushed Khan up to the desk, caused the sergeant to look at him, then at Henry, then back to Khan.
âHello, Dr Khan.'
Khan nodded miserably.
âDo you know this person,' the sergeant said to Henry, âis one of our police surgeons?'
Henry gave him a pained look. âHow would I know that?'
âYou wouldn't.' He smiled thinly at Henry. âWhat's this about?'
âI've arrested him on suspicion of murder.'
Once again the sergeant glanced from one person to the other. âMurder?' he said in disbelief.
âMurder,' Henry confirmed.
âWhich murder?'
âThat of a woman called Sabera Ismat, whose body was found in Lancashire about six months ago. I was the SIO,' he concluded.
âDo you have anything to say, Dr Khan?'
Khan shook his head, but he was clearly affected by what Henry had just said. The sergeant again gave Henry a stare which said it all, and with a heavy sigh began the process of detaining Khan under the Police and Criminal Evidence Act, not impressed.
It was four miserable hours before a duty solicitor became free and the time was approaching 3 p.m. Henry had expected to be on his way back to Lancashire by now.
His newly formulated plan was to have a quick interview with Khan and then arrange for him to be transported up north where he could be dealt with properly.
They were in a grotty interview room with peeling paint on the walls and a strange smell of sewers. Henry had the tape on and had cautioned Khan.
âI'm investigating the murder of Sabera Ismat whose body was found six months ago in a field in Lancashire,' he began. It was the first time Henry had actually been face to face with Khan properly. He was a good-looking Asian man around about the thirty mark. As he spoke the words, the colour of Khan's skin faded to a grey. He looked as though he was about to say something, but nothing came out.
âYou knew her, didn't you?'
âThat doesn't make my client a murderer,' the weasley-faced brief interjected. âI already have the feeling that this is a purely speculative arrest.'
Henry ignored him. âPlease answer the question. Did you know her?'
âI knew her. She used to be a locum for the practice.'
âHow well did you know her?'
Khan rubbed his head. âNot that well.'
âHow well would you say on a scale of one to ten?'
Khan thought. âFour, maybe.'
Henry gave him a withering look.
âI'd met her back in med school, but then I didn't see her again until a few months ago when she came asking about a job.'
âWhich you got her?'
âI did.'
âWithout even a formal interview.'
Khan's face turned stonily towards Henry. âIt was based on her references, qualifications and my personal knowledge.'
âYet you say you didn't know her that well?' Henry paused. He liked waiting. It made people feel uncomfortable and often they had the urge to fill in the gaps. If used well, silence could be a deadly trap, a void into which the unwitting could tumble. Khan, though, just looked down at his hands as his fingers intertwined in anguish. His chin shook.
âWhere are her employment records?'
âWhat do you mean?'
âI mean, they seem to have disappeared from the filing cabinet in which all the health centre employment records are kept.'
âNo idea.' His eyes closed and opened slowly as he said the two words.
âHow come you haven't asked me more about the fate of one of your employees? Someone you knew from university, someone you gave a job to, someone who then suddenly disappeared? Aren't you curious about what happened to her? Or is it that you already know?' Henry was still aware that he did not have a hundred per cent proof that the dead woman was Sabera Ismat and that Khan could feasibly tell him where she was, alive and kicking ⦠although his marked reluctance to say anything convinced Henry he was on the right track.
The woman in the photos was Sabera Ismat and Dr Khan, renowned police surgeon, damn well knew something about her.
And yet, there was something about this man that made Henry doubt he could have killed her ⦠but he'd been wrong about killers before. Everyone â
everyone
â was capable.
Khan remained silent. He was sweating and Henry almost believed he could hear the man's heart beating against his rib cage.
âDr Khan, you have a lot of questions to answer. I'm going to arrange for you to be conveyed to Lancashire for further questioning. You are a very good suspect for her murder. You knew her, you employed her, and I'll prove you pulled her records when she mysteriously disappeared. And while I'm waiting for transport from Lancashire, I'll be going to arrest your receptionist too. She can have a trip up north, because you're obviously both in this togetherâ'
âNo!' Khan erupted. âNeither of us hardly knew her! Aysha â¦' His voice tapered out.
Henry reached down for his briefcase at his feet under the interview table. He laid it on his lap, opened it and pulled out two sheets of paper, which he positioned face down in front of Khan.
âFor the benefit of the tape I am showing Dr Khan two photographs. The first shows him sitting at a restaurant with the victim, Sabera Ismat.' Henry slowly turned the photograph over and slid it across to Khan so it was right under his nose. Henry's eyes remained firmly fixed on Khan's reactions. âThe second is a photograph of Khan embracing the victim, as though they were lovers.' He did the same with this one, the photograph taken of Khan and Sabera holding each other on a bridge. Khan's face was a picture to behold. âSo, Dr Khan, just run that past me again, will you? How well do you know Sabera Ismat?'
The next problem was arranging transport from Lancashire to come down to London and pick up the prisoner. Not the easiest thing to arrange because it meant two uniformed bobbies coming down from Blackpool, as that was the division in which the body was discovered, who had to be released from other duties to tear down south.
Henry wrestled with it, working it all through his head; how long it would take to get them down to London, how long back, how it would all impact on the time factor in relation to the prisoner. He was sitting in the police surgeon's room, weighing up the factors, hand on the phone, when the custody sergeant came in.
âGuv,' he said, âDr Khan wants to see you. Says he's got something to tell you.'
Henry jumped up and hurried through to an interview room to await the arrival of Khan and his solicitor. He was surprised when only Khan was escorted through by a gaoler. He sat down opposite Henry, clearly crushed and worried.
âWhere's your brief?'
âSacked him.'
âIs that wise?'
âI don't think he was very wise.'
âWhat do you want to tell me?' Henry unwrapped a double-pack of cassette tapes and dropped them into the machine.
Khan took a deep, unsteady breath.
N
ot even 125 mph was fast enough for Henry Christie. As the early morning Virgin Express Pendolino service left the environs of London and scythed north-west towards Rugby, even his full English breakfast, as good as it was, hardly tickled his taste buds. Once again he read through the twelve-page statement he had painstakingly extracted from Dr Sanjay Khan, the man he had suspected of murdering Sabera Ismat â or, as Khan had corrected him, Sabera Rashid.
On the previous evening Henry had listened with fascination, and then with a chilled heart, as Khan spilled the truth and recounted the story of a beautiful young woman whose hopes of freedom and a decent life had been cruelly terminated.
It took him half an hour to haltingly tell the tale the first time round, after which Henry took him from the suspect interview room and found a more comfortable room in the police station in which he could get Khan to relax and expand on everything whilst Henry recorded the statement on paper.
It was clear that Khan was a man who, underneath his veneer of being a normal GP and police surgeon on the side, lived in fear. He looked desolate, afraid.
âYes, we fell in love,' he said painfully, tears welling in his eyes. âIt was wrong, but it was also very, very right.'
Henry made a guggling sound to encourage him.
âAll she wanted was freedom, the right to be her own person, to follow her vocation, but that was denied her by a tyrant of a husband who beat and raped her most horribly ⦠we met at university and we were just good friends, though there was a spark.' He looked desperately at Henry. âWe knew she would return to get married and that was accepted between us, so nothing happened in those days â¦' His story was all over the place at first, but Henry allowed him his ramble before putting structure to it. âThen she came back to me out of the blue ⦠I'd never married ⦠and she told me she had left her husband and wanted a new life. God, it was so hard for her ⦠so much pressure on her from inside and outside, but she knew that when she had made that step, returning was out of the question ⦠those photographs you showed me ⦠taken by a private investigator?'
âI think so.'
âSo she was tracked down, got careless I suppose. Her husband had that sort of money, though. He is quite wealthy, I believe.' Khan paused. âThat night, the night of the photographs, was the last night I ever saw her â¦'
Henry was running these words through his mind when the train began to slow down, then stop ⦠in the middle of nowhere. South of Milton Keynes, he guessed. The regretful announcement was that there would be a short delay whilst a broken down train ahead of them was removed from the lines. Henry cursed, but smiled when the pretty stewardess appeared by his side offering more coffee. There was nothing he could do about any delays. Not as though he could get out and kick the wheels, call the AA or remonstrate with anyone. If a train ain't going nowhere, it ain't going nowhere. He held up his cup. The coffee was good.
Dressed in jeans, trainers and leather jacket, he relaxed in the business-class seat. He was at an individual table so he stretched out and thought back to the evening.
âWhat happened that night?' he had asked Khan.
Khan snorted, shaking his head sadly. âShe had been in London for about six months. She was working hard, doing well, and we were falling in love slowly, at arm's length, yeah? To leave her husband was one thing for a Muslim girl; to start seeing another man whilst still married, that's a whole new ball game. Very big stuff for a Muslim female. Monumental, in fact. But it started to happen and the irony was that it happened on that night of all nights.'
âMeaning?'
Khan sat back, remembering. âRomantic meal, romantic stroll across the river, back to my flat where' â he hesitated with an embarrassed cough â âwe made love.'
Henry nodded, feeling very sorry for this man. Not that he was going to let him off the hook, though. He'd been spun many a lying sob story by murderers trying to get sympathy and walk free. âAnd after that, you never saw her again?'
Khan nodded.
âMeaning you killed her? Isn't that right?'
âNo! Never!' he protested.
Henry gave him a look of disbelief. âKeep talking.'
âShe stayed the night at my flat ⦠and at about four in the morning, something like that, the door was kicked inâ' He stopped abruptly at that point and dropped his head into his hands, beginning to sob. Henry let him get it out of his system.
Finally, when it looked as though he had finished his snivelling, Henry said, âThe husband?'
âHim and three other guys. They came in hard and fast and I didn't do a damn thing to protect her. They put tape over her face, tied her up and rolled her into my duvet and carried her out. And I just watched. I was shitting myself.'
âYou just watched?'
âYeah â with one guy holding a knife to my throat.' He raised his chin and pointed to a small, silvery scar by his windpipe.
âAhh,' said Henry, understanding.
âThen I was warned off, I guess by Sabera's husband, although he didn't introduce himself.'
âThat was it? They warned you off?' Henry said incredulously.
