The strain gave him a headache, and his sitting position made his back hurt. He also felt hungry.

He opened the window for a cold breeze to keep him awake, but so much water came in that he was immediately forced to close it again. He thought about Die Nadel, or Faber or whatever he was calling himself now: a smiling young man in running shorts, holding a trophy. Well, so far Faber was winning this race.

He was forty-eight hours ahead and he had the advantage that only he knew the route that had to be followed. Bloggs would have enjoyed a contest with that man, if the stakes had not been so high, so bloody high.

He wondered what he would do if he ever came face to face with the man. I'd shoot him out of hand, he thought, before he killed me. Faber was a pro, and you didn't mess with that type. Most spies were amateurs: frustrated revolutionaries of the left or right, people who wanted the imaginary glamour of espionage, greedy men or lovesick women or blackmail victims. The few professionals were very dangerous indeed; they were not merciful men.

Dawn was still an hour or two away when Bloggs drove into Aberdeen. Never in his life had he been so grateful for street lights, dimmed and masked though they were. He had no idea where the police station was, and there was no one on the streets to give him direction so he drove around the town until he saw the familiar blue lamp (also dimmed).

He parked the car and ran through the rain into the building. He was expected. Godliman had been on the phone, and Godliman was now very senior indeed. Bloggs was shown into the office of Alan Kincaid, a detective chief-inspector in his mid-fifties. There were three other officers in the room; Bloggs shook their hands and instantly forgot their names. Kincaid said: "You made bloody good time from Carlisle."

"Nearly killed myself doing it," Bloggs replied, and sat down. "If you can rustle up a sandwich…"

"Of course." Kincaid leaned his head out of the door and shouted something. "It'll be here in two shakes," he told Bloggs.

The office had off-white walls, a plank floor, and plain hard furniture: a desk, a few chairs, and a filing cabinet. It was totally unrelieved: no pictures, no ornaments, no personal touches of any kind. There was a tray of dirty cups on the floor, and the air was thick with smoke. It smelled like a place where men had been working all night.

Kincaid had a small moustache, thin grey hair and spectacles. A big intelligent-looking man in shirtsleeves and braces, he spoke with a local accent, a sign that, like Bloggs, he had come up through the ranks, though from his age it was clear that his rise had been slower than Bloggs'.

Bloggs said: "How much do you know about all this?"

"Not much," Kincaid said. "But your governor, Godliman, did say that the London murders are the least of this man's crimes. We also know which department you're with, so we can put two and two together about this Faber…"

"What have you done so far?" Bloggs asked.

Kincaid put his feet on his desk. "He arrived here two days ago, right? That was when we started looking for him. We had the pictures- I assume every force in the country got them."

"Yes."

"We checked the hotels and lodging houses, the station and the bus depot. We did it quite thoroughly, although at the time we didn't know he had come here. Needless to say, we had no results. We're checking again, of course: but my opinion is that he probably left Aberdeen immediately."

A woman police constable came in with a cup of tea and a very thick cheese sandwich. Bloggs thanked her and greedily set about the sandwich.

Kincaid went on: "We had a man at the railway station before the first train left in the morning. Same for the bus depot. So, if he left the town, either he stole a car or he hitched a ride. We've had no stolen cars reported, so I figure he hitched-"

"He might have gone by sea," Bloggs said through a mouthful of wholemeal bread.

"Of the boats that left the harbour that day, none was big enough to stow away on. Since then, of course, nothing's gone out because of the storm."

"Stolen boats?"

"None reported."

Bloggs shrugged. "If there's no prospect of going out, the owners might not come to the harbour, in which case the theft of a boat might go unnoticed until the storm ends."

One of the officers in the room said, "We missed that one, chief."

"We did," Kincaid said.

"Perhaps the harbour-master could look around all the regular moorings," Bloggs suggested.

"I'm with you," Kincaid said. He was already dialling. After a moment he spoke into the phone.

"Captain Douglas? Kincaid. Aye, I know civilised people sleep at this hour. You haven't heard the worst: I want you to take a walk in the rain. Aye, you heard me right…" Kincaid put his hand over the mouthpiece. "You know what they say about seamen's language? It's true." He spoke into the phone again. "Go round all the regular moorings and make a note of any vessels not in their usual spot. Ignoring those you know to be legitimately out of port, give me the names and addresses and phone numbers, if you have them, of the owners. Aye. Aye, I know… I'll make it a double. All right, a bottle. And a good morning to you too, old friend." He hung up.

Bloggs smiled. "Salty?"

"If I did what he suggested I do with my truncheon, I'd never be able to sit down again." Kincaid became serious. "It'll take him about half an hour, then we'll need a couple of hours to check all the addresses. It's worth doing, although I still think he hitched a ride."

"So do I," Bloggs said.

The door opened and a middle-aged man in civilian clothes walked in. Kincaid and his officers stood up, and Bloggs followed.

Kincaid said, "Good morning, sir. This is Mr Bloggs. Mr Bloggs, Richard Porter."

They shook hands. Porter had a red face and a carefully cultivated moustache. He wore a double-breasted, camelcoloured overcoat. "How do you do. I'm the blighter that gave your chappie a lift to Aberdeen. Most embarrassing." He had no local accent.

Bloggs said, "How do you do." On first acquaintance Porter seemed to be exactly the kind of silly ass who would give a spy a lift half across the country. However, Bloggs realised the air of empty-headed heartiness might also mask a shrewd mind. He tried to be tolerant-he, too, had made embarrassing mistakes in the last few hours.

"I heard about the abandoned Morris. I picked him up at that very spot."

"You've seen the picture?"

"Yes. Of course, I didn't get a good look at the chappie, because it was dark for most of the journey. But I saw enough of him, in the light of the flashlight when we were under the hood, and afterward when we entered Aberdeen. It was dawn by then. If I'd only seen the picture. I'd say it could have been him. Given the spot at which I picked him up, so near to where the Morris was found, I say it was him."

"I agree," Bloggs said. He thought for a moment, wondering what useful information he could get out of this man. "How did Faber impress you?"

Porter said promptly: "He struck me as exhausted, nervous, and determined, in that order. Also, he was no Scotsman."

"How would you describe his accent?"

"Neutral. The accent minor public school, Home Counties. Jarred with his clothes, if you know what I mean. He was wearing overalls. Another thing I didn't remark until afterwards."

Kincaid interrupted to offer tea. Everyone accepted. The policeman went to the door.

"What did you talk about?"

"Oh, nothing much."

"But you were together for hours."

"He slept most of the way. He mended the car-it was only a disconnected lead, but I'm afraid I'm helpless with machines-then he told me his own car had broken down in Edinburgh and he was going to Banff. Said he didn't really want to go through Aberdeen, as he didn't have a Restricted Area Pass. I'm afraid I… I told him not to worry about that. Said I'd vouch for him if we were stopped. Makes one feel such a bloody fool, you know, but I felt I owed him a favour. He had got me out of a bit of a hole, y'know."
