"And afterwards? I mean you obviously gave up acting or I'd have heard of you."

"Not entirely. You might say I took a considerable interest in what might be termed the theater of the street back home in the old country."

"Strange," she said. "If I had to guess I'd say you'd been a soldier."

"And who's the clever girl then?"

"Damn you, Dillon," she said. "Mystery piles on mystery with you."

"You'll just have to unpeel me layer by layer like an onion, but that would take time."

"And that's exactly what I don't have," she said. "I'm going up to Scotland tomorrow."

"I know," Dillon said. "There was a mention in Nigel Dempster's gossip column in the Mail this morning. 'Carl Morgan takes the lease on a Highland Estate for the shooting,' that was the byline. It also said you were standing in for him tonight at the Brazilian Embassy Ball."

"You are well informed."

They had reached Lambeth Bridge by now and found the Mercedes waiting. Dillon handed her in. "I enjoyed that."

"I'll drop you off," she said.

"No need."

"Don't be silly, I'm curious to see where you live."

"Anything to oblige." He got in beside her. "Stable Mews, Henry, that's close to Cavendish Square. I'll show you where when we get there."

When they turned into the cobbled street, it was still raining. He got out and closed the door. Asta put the window down and looked out at the cottage.

"All in darkness. No lady friend, Dillon?"

"Alas no, but you can come in for a cup of tea if you like."

She laughed. "Oh, no, I've had enough excitement for one night."

"Another time perhaps."

"I don't think so. In fact, I doubt whether we'll ever see each other again."

"Ships that pass in the night?"

"Something like that. Home, Henry," and as she put up the window the Mercedes pulled away.

Dillon watched it go, and as he turned to open the door he was smiling.

It was peaceful in the small railway station by the lochside and Dillon peered out of the rear compartment keeping out of sight. Following her had been easy. The Lear had taken him to Glasgow Airport at breakfast time and he had waited until Asta had arrived on the morning shuttle from London, had followed her down to the central railway station. Keeping out of the way from Glasgow to Fort William had been easy, for the train was busy with many tourists here to see Loch Lomond and afterwards the spectacular mountain scenery of the Highlands.

The smaller, local train from Fort William to Arisaig had been more difficult, for there were only a handful of passengers and he'd kept out of sight, only leaping into the rear compartment at the last moment. The station they had stopped at now was named Shiel according to the board at one side of the ticket office. They seemed to be standing there for quite some time. It was very pleasant, a mountain above them rearing three thousand feet into the clear blue sky, sunlight glinting on a waterfall that spilled over granite into birch trees.

Asta Morgan suddenly stepped onto the platform. She wore a leather jacket and linen slacks and leather brogues. She made an attractive sight in the quiet setting. She moved across to the ticket collector who stood at the barrier. There was some conversation, a burst of laughter, and she went through the barrier.

The ticket collector moved to join the guard, who was standing by the open door beside Dillon. "You've lost a passenger, Tom."

"Do you tell me?"

"A bonny lass, a Miss Morgan, hair of corn and a face to thank God for. Her father is yon fella Morgan that's just leased Loch Dhu Castle. She's away over the mountain. You'll put her luggage down at Arisaig and leave a message."

Dillon grabbed his Burberry trenchcoat and brushed past the guard. "Do you mean there's a shortcut over the mountain?"

"Well that would depend where you want to be."

"Ardmurchan Lodge."

The guard nodded. "Over the top of Ben Breac and a twelve-mile walk to the other side. You'll be staying with Brigadier Ferguson, the new tenant?"

"My uncle, he'll be waiting at Arisaig. Perhaps you could tell him where I am and give him my luggage." Dillon slipped a five-pound note into his hand.

"Leave it to me, sir."

The guard blew his whistle and boarded the train. Dillon turned to the ticket collector. "Where do I go?"

"Through the village and over the bridge. There's a path through the birches, hard going, but you can't miss the cairns that mark the way. Once over the top the track is plain to the glen below."

"Will the weather hold?"

The man looked up at the mountain. "A touch of mist and rain in the evening. I'd keep going, don't waste time on top." He smiled. "I'd tell the young lady that, sir, no place for a lassie to be on her own."

Dillon smiled. "I'll do that, a pity to see her get wet."

"A thousand pities, sir."

At the small village store he purchased two packs of cigarettes and two half-pound bars of milk chocolate for sustenance. Twelve miles on the other side of the mountain and that didn't count the miles that stood up on end. Something told him he could be hungry before he reached Ardmurchan.

He marched down the street and crossed the bridge. The track snaked up through the birch trees, lifting steeply, bracken pressing in on either side. It was cool and dark and remote from the world, and Dillon, thanks to his renewed energy, was enjoying every moment of it. There was no sign of Asta, which suited him for now.

The trees grew sparser and he emerged onto a bracken-covered slope. Occasionally grouse or plover lifted out of the heather disturbed by his presence and finally he came to a boulder-strewn plain that stretched to the lower slopes of Ben Breac. He saw Asta then, six or seven hundred feet up on the shoulder of the mountain.

She turned to look down and he dropped into the bracken. When he glanced up a few moments later, she had disappeared round the shoulder of the mountain. She was certainly moving fast, but then she was young and healthy and the track was plainly visible.

There was another way, of course, though only a fool would try that, which was straight up the breast of the mountain and the granite cliffs beyond to the summit. He took out an Ordnance Survey map of Moidart and had a look at the situation. Dillon glanced up. What the hell, strong nerves were all that was needed here, and with luck he might actually get ahead of her. He tied his Burberry around his waist and started up.

The lower slopes were easy going with his new-found strength, but after a half hour he came to a great cascading bank of scree and loose stones that moved beneath his feet alarmingly. He went to his left, found the waterfall he'd noted from the station, and followed its trail upwards, moving from boulder to boulder.

Finally, he reached the plateau and the final cliffs were before him and they were not quite as intimidating as they'd looked from the station, fissured with gullies and channels reaching to the top. He looked, checking his route, ate half a bar of chocolate, then made sure his raincoat was secure and started up, climbing strongly, testing each handhold. He looked down once and saw the railway station in the valley below like a child's toy. The next time he looked it had disappeared, blanked out by mist, and a sudden breeze touched him coldly.

He came over the granite edge to the summit a few minutes later to find himself cocooned in mist and he'd spent enough time in hill country in the past to know that there was only one thing to do in such conditions. Stay put. He did just that, lighting a cigarette, wondering how Asta Morgan was getting on. It was a good hour later when a sudden current of air dissolved the curtain of the mist, and down there the valleys lay dark and quiet in the evening sunlight.
