FIVE

      I

      A wasp had taken an uncomfortable interest in Luke’s hair, buzzing around his collar and ears. And something large and ticklish was making its way up inside his trouser leg. But he lay absolutely still until his heartbeat had moderated a little, until he’d heard nothing but birdsong for at least five minutes. He got carefully to his knees, peered through the grasses and the ferns. No sign of them. He rose to a stoop then ran away from the house, chased by little flurries of panic.

       Now what?

      He needed to call the police, of course, but how? His mobile was back in the attic and he couldn’t see any houses, not so much as a farm building. These were the Fens, after all, about the least-densely populated part of England. He checked his pockets, found some pound coins and other loose change; hardly enough to fund a new life in South America, but better than nothing. He headed onwards, listening intently. Engines kept screeching in the far distance, motorcycles at full throttle. He’d seen signs earlier for some biker festival; presumably they were gathering for it. He reached a farm track, followed it between fields of rape and wild poppies. An automated irrigation system began to spray, painting rainbows in the sky. A farmhouse ahead, a sagging roof and lichen shadows on its cream walls. He rang its doorbell, banged and shouted. No one answered. He considered, briefly, smashing a window. But it was too late to help Penelope, and his record would make life tough enough with the police without adding a burglary charge, so he turned and hurried on.

      A flight of fighter jets queued to land at a nearby air-force base, noses up like snotty guests. Mildenhall, most likely. There had to be houses that way. He reached more woods, ground crackling with dried branches and twigs, emerged onto a winding country lane. It looked faintly familiar. He’d got a little lost earlier, trying to find Penelope’s house. If this was the road he thought it was, there should be a T-junction ahead, with a road that led down to a hamlet with a pub.

      There was no traffic at all. All those people moaning about overpopulation should move here. He’d been jogging five minutes before he heard a car coming up fast behind. He stepped off the lane to wave it down when, looking back through a hedgerow on a bend, he glimpsed its black bodywork and tinted windows. He threw himself down and the SUV sped on by. He tried to catch its licence plate, but it was going too fast. It slowed for the T-junction, indicated right, and vanished from sight.

      There were sirens in the distance as he hurried down the hill. He ignored them. The hamlet’s pub was old, low and thatched, with a beer garden to one side and a car park on the other. He caught sight of his reflection in the front windows and was shocked by what a mess he looked. He decided to go around back in hope of a rear door and a payphone.

      A handwritten sign offered a warm welcome to anyone attending BikerFest. That invitation had been gladly accepted, if the fifteen or so motorcycles parked outside the low, modern extension were anything to go by. Luke slipped inside. It proved to be a games annexe, large and gloomy except for two spotlit pool tables and a dartboard, plus a bank of fruit machines and arcade games. Middle-aged bikers with grey-streaked hair, black leather jackets and spotted bandannas drank pints of soupy ale. The payphone was next to a large varnished pine table, where two bikers were keeping an eye on a great mound of wallets and keys. One of them grinned at him as he passed, daring him to try his luck. Luke turned his back on him to dial the emergency services. A bored-sounding woman answered. ‘Name?’

      ‘Hayward. Luke Hayward.’

      ‘Address?’ she asked.

      ‘Martyn’s Hall,’ he said. ‘Near Mildenhall.’

      ‘Is this about the fire?’

      ‘Fire?’ he frowned. ‘No. This is …’ Then he remembered the sirens and stopped dead. Steven and his friends must have set fire to the house, destroying any and all evidence that they’d ever been there. And his own car was sitting outside the front door! Shit! If they been smart enough to disable it before they’d left, the police would inevitably conclude that he’d killed Penelope himself, then had set fire to her house intending to cover his tracks only to find himself trapped there by a car that wouldn’t start. They’d run his licence, get his name, learn of his convictions for assault and making threats against the authorities. And what would his defence be? An absurd story about a mysterious Newton collector, an anonymous lawyer and a generic email address. They’d laugh themselves sick.

      ‘Sir? Are you still there, sir?’

      He muttered a curse, slammed down the phone. This was a nightmare. He needed to think. If the police got hold of him now, they wouldn’t bother looking for other explanations, they’d arrest him and charge him and lock him away, giving those three men all the time in the world to cover their tracks. He was screwed. He was completely screwed.

      It was only then that he remembered the email Penelope Martyn had sent her niece. Not much, but something; a piece of evidence that would corroborate his account. And it had freaked those men out, that was for sure. But maybe it had freaked them out badly enough to do something about it. Cambridge was just forty minutes drive away, after all.

      The phone took cards, not coins. He had just enough change to buy one from a dispenser. He called Directory Enquiries, had them put him through to Caius College. ‘Rachel Parkes, please,’ he said.

      ‘She’s not here,’ said a man. ‘May I take a message?’

      ‘I need to speak to her now. Do you have a mobile number for her?’

      ‘I couldn’t possibly give out that kind of information.’

      ‘Then can you at least get a message to her?’

      Hesitancy in his voice. Anxiety that this might actually be serious. ‘I’m afraid Ms Parkes is out of Cambridge this afternoon, and she doesn’t have a mobile. I could ask her to contact you if she calls in.’

      Luke hesitated. He could hardly wait here all day on the off chance. ‘I’ll try again later,’ he said. He put the phone down, stood there in thought. What he really needed was someone to look for Rachel on his behalf, someone who knew Cambridge and who trusted him enough to do it without asking awkward questions.

      Pelham, then.

      He called Directory Enquiries again, asked for his
