'When isn't it? There's Dunkeswell.'
Marler looked out of the window, frowned. Two main runways crossed each other almost at right angles. One had lights on at either side. Ready for a plane to take off?
The chopper was descending towards a deserted country road. Marler grabbed his rifle, headed for the door after one last word.
'Land me on that road. Then you'd better take off, head back for Fairoaks…'
He tore off his headset, splaying his feet as he made for the door. The machine was rocking gently. He felt it touch down, opened the door, dropped to the ground. Ducking to keep clear of the rotors, he ran towards the main airport building. He reached the open gate at the main entrance as an old Rover driven by a middle-aged man appeared from the opposite direction. The car stopped, half-turned to drive through the entrance. The driver lowered his window, leaned out.
'Who are you?' he enquired, staring at the rifle Marler held in his right hand.
'Don't go in there,' Marler warned. He used his left hand to extract his Special Branch card, shoved it in the driver's face. 'And who are you?'
'I'm the controller of this airfield. Those damned gates should be kept closed. I've told Abbott before…'
'Who is Abbott? Quick. There's probably an armed terrorist inside.'
'Maintenance mechanic. Odd-job man. Really runs the place…'
'Where do I find this Abbott?'
'Should be inside that office with the lights on…'
'Drive off. Up the road. Unless you want to risk getting shot.'
Marler darted inside the entrance, crouched low as he ran, rifle gripped in both hands. He avoided the office door, which was closed. Very carefully he raised his head, peered in through the window. Then he ran back to the door, turned the handle, threw it open. He had found Abbott.
The mechanic was sprawled forward over a desk. Blood was congealing from a hole in the side of his skull. Marler felt the neck pulse. Nothing. In the distance he heard the sound of a light aircraft starting up. He ran outside, keeping close to the side of the building, peered round the corner.
A Cessna was taxiing slowly along a runway. As he watched, it turned. The engine revolutions increased in speed. He raised his rifle, peered through the sight. Inside the cockpit a face wearing a pilot's helmet jumped at him. Anton Gavalas. The machine began to move forward along a course parallel to the building. Moving target. Marler held the crosshairs fixed on the Greek's head. He took the first pressure on the trigger, waited until the small plane was opposite him, pulled the trigger rapidly three times.
He saw the perspex craze. The aircraft proceeded on down the runway. Marler thought he'd missed. The machine began leaving the ground. It was gaining height when the nose dipped and plunged swiftly down on to the runway. The tail was poised in mid-air. Then the fuel tanks exploded. Fire enveloped the Cessna, a fierce blaze which was smothered with a cloud of the blackest smoke. Silence suddenly descended on Dunkeswell.
'Lord, I'm glad to see you.'
Paula jumped out of the Mercedes parked by the call box in Minehead as the Cortina driven by Newman pulled up. It was dark as Tweed stepped out and she hugged him. 'They go to bed early here,' Tweed commented, glancing along the deserted street. He squeezed her, let her go as Newman approached.
'Look what Inspector Farthing gave me.' She took them both by the arm, guided them to the Mercedes and pointed at the dashboard. A mobile phone unit had been attached. Tweed got in behind the wheel, pressed the switch which operated the aerial and watched it slide down out of sight in the wing mirror.
'No, elevate that,' Paula protested as she got in beside him and dropped her shoulder bag in her lap. 'It helps contact. Farthing has a policeman with a walkie-talkie watching each of the houses. Barrymore, Robson and Kearns. They report back to a radio car and I hear their observations over that phone. In a kind of code I can understand. They're all at home. Farthing has been marvellous.'
'I have to get moving,' Tweed said as he elevated the aerial. 'Bob, take Paula with you. Drive to The Anchor and keep your eyes open.'
'For what?' Newman asked.
'In case he gets away from me. I'd say a four-wheel drive – heading past The Anchor and west over that pebble beach. And cover him with that Magnum. He's lethal. Out you get, Paula.'
'I'm coming with you.' She spoke calmly and produced from her bag the Browning. 'I can protect myself. I did with Norton and Mode.'
It was the controlled way she spoke which stopped Tweed arguing. He shrugged, glanced at the call box. 'Has Barrymore used that this evening?'
'Not so far.'
'Then we'd better move off.' He waved to Newman, drove through Minehead and climbed Porlock Hill. The Mercedes purred up the steep ascent. At the top he passed Culbone Inn, continued along the coast road, took the first turning to the left.
'It's the Doone Valley,' Paula said quietly as they descended the steep winding lane, crossed the ford at the bottom, turned right. Towards the Doone Valley.
'We located the two furniture vans they were using as mobile missile launcher platforms,' Tweed remarked. 'Just in time. One was blown to bits. Marler found a dead Middle Easterner in his. Maybe a Shi-ite. They were going to be left behind as the scapegoats. Monica read out a news story about two Arabs being airlifted from Gartree Prison. Shi-ites.' He stopped and backed the car through a gap in the hedge into a field, switched off the lights. 'No one will see you here. Keep the Browning in your lap until I get back.'
'You've stopped midway between Quarme Manor and Endpoint.'
'Lock all the doors,' Tweed said, then he was gone.
He pressed the bell. The man who opened the door was dressed in a leather windcheater unzipped down the front, cavalry twill trousers tucked into riding boots, a woollen scarf round his neck. The hall beyond was as cold as the biting wind moaning across the moor.
'May I have a word with you, Dr Robson?' Tweed asked.
'Come in, my dear fellow. Can't give you long. I'm expecting a call from a patient. They phone me at all hours. Goes with the territory as the Americans say.'
All this as Robson closed the door, led the way into the sitting room. The curtains were almost drawn with a gap where they should have met. Tweed sat down at a polished wooden table as Robson gestured and then sat opposite him. His host moved an old-fashioned doctor's bag on to the floor by his side without bothering to close it.
'I've come to arrest you for murder,' Tweed said. 'Quite a few murders. You've probably heard on the news your plan failed. Gorbachev is now in Washington.'
Robson's face crinkled into a smile. His pale blue eyes watched Tweed as he pulled at his straggly moustache.
'I don't follow any of this. You look sane enough.'
'One thing which pinpointed you was your conversation at The Luttrell Arms over dinner. Barrymore referred to the Greek Key. You pooh-poohed the idea. Out of character. When you all had houses like fortresses. Especially this place. I asked my man Nield, who was recording secretly, who was facing him. Barrymore was. So were you. The tape sounded like someone had spotted the tie pin microphone Nield kept fiddling with to get the right angle. And you made the mistake of asking Barrymore if Nield was wearing an earpiece when he met him on the moor. Only a professional would spot that. You spotted it. Hence your strange remark – considering you were all supposed to be scared stiff someone was coming from Greece to avenge the murder of Ionides. ..'
'Gavalas…'Robson stopped. His expression changed. The eyes were blank and cold.
'I never told you Ionides was a Gavalas,' Tweed remarked.
Robson sat very still. The only illumination was a plastic-shaded bulb which hung low above the table. Robson reached down into his bag. He pointed the Luger as Tweed reached inside his jacket.
'Don't bring your hand out with anything in it but your fingers. I still find your reasoning feeble.'
'Winterton – as we codenamed the killer- needed access to a safe phone. You wouldn't like using the one here. Your sister, May, could have overheard you. Where is she?'
'I sent her off for a holiday to my brother's place in Norfolk
'You needed access to a safe phone,' Tweed continued, 'to keep in touch with the Spetsnaz group you'd set
