“Any leads on the poison angle?” Brennan asked.

“None at all, sir, I am sorry to say. Abrin is an extremely rare substance. I don’t know who the hell would have taken the trouble to refine and process it or why they would have used it as a murder weapon on an island filled to the brim with guns.”

He nodded and blew smoke at the brown stain on the ceiling that uncannily resembled Margaret Thatcher’s hairdo. “I’m sure it’s going to take you into some interesting areas, but do me a favour, don’t let it get too complicated, will you, Sean?” Brennan muttered. He shifted his weight from his left to his right side. He grunted and rubbed his eyelids. “Do you hear me, son?”

“Yes, sir,” I replied. “I’ll keep it simple, you know me.”

“I do know you, pal, that’s the bloody trouble.”

I nodded, drank the rest of the whiskey and got to my feet.

“And Duffy?”

“Yes, sir?”

“That Elvis story is just between us,” Brennan said.

“Of course, sir,” I replied and exited the office.

9: BLOOD ON THE TRACKS

Someone passed me a brandy to help “batten down the hatches on our breakfasts”. I’d only had a coffee but I took a swig of the flask anyway and passed it back.

I walked to the top of the hill and waved away the oncoming traffic. I wasn’t properly in uniform. No shirt, no tie, just black trousers and a black sweatshirt under my flak jacket which said “Police” on it in yellow letters. I was wearing my green uniform hat and fidgeting with a Sterling submachine gun loaded with a 25-round clip. The same gun I’d used to repel the attack on Coronation Road and win me my police medal and my invitation to Buckingham Palace.

I was fiddling with the gun rather than looking downhill at the carnage. Everyone was compensating in their own way. One guy was whistling, two other cops were talking about the football. That was their way of not being in the present. “We have better things to do with our time than direct traffic,” Matty was grumbling to Crabbie because he knew better than to grumble to me.

“You do what you’re told to do and that’s an end to it,” Crabbie told him and like a good Free Presbyterian refused the brandy and passed it back to me. I shook my head and walked along the lane to where a dead cow was lying in the sheugh. Killed by the concussion shock wave or a random piece of debris. I looked down into the valley. The helicopter’s spotlights were still scouring the scene in the predawn light, even though everyone was now accounted for: the dead, the dying, the miraculously survived. I lit a Marlboro and drew in the good, safe, dependable American tobacco. It comforted me. I sat on a tree stump and watched the helicopter’s powerful incandescent spotlight beams meditating on the pulverised brick and stone, on the smashed breeze block walls, on the cars ripped inside out. I watched as the rotors sucked embers, paper fragments and debris into the sky in huge anti-clockwise spirals.

That comforted me too, making me feel that something, anything, was being done. Half an hour passed this way, then dawn made its presence felt across the landscape and the chopper banked to the left and flew back to RAF Aldergrove.

I could see the full havoc wrought on Ballycoley RUC station, now.

It was a country police barracks and with only a thin brick wall around the perimeter, which was why it had been chosen for the terrorist attack. The main building itself had been flattened and a portacabin structure in the rear had been tossed halfway up the nearest hill. Many of the surrounding houses had been wrecked, part of a railway line had been ripped up and an electricity substation destroyed. It was lucky that the number of civilian casualties wasn’t higher.

With the Wessex gone the valley was relatively quiet.

Cops talked to one another, radios crackled, generators hummed and a massive yellow digger pawed at the rubble like a brachiosaurus over its dead young.

I went back to the other officers and we shared smokes and turned away a milk delivery lorry and explained what had happened to the bemused driver. “There’s been an incident, the road’s closed for the time being, mate, you’ll have to find an alternative route …”

“What happened?”

“A bomb blast in the wee hours down at the police station there.”

“Anybody dead?”

“Aye. Four.”

The driver nodded and turned his car around. Ballycoley RUC was only six miles from Carrickfergus but I didn’t know any of the deceased. Two of them were peelers, one was the driver of the bomb vehicle and one was a civilian woman, a widow who lived across the road and who apparently had been eviscerated by her own disintegrating bedroom windows.

Matty yawned. “How much longer are we going to have to stand here like eejits, Sean?” he asked me.

I shook my head. “I’ll go down there and find out.”

I walked down the slurry slope into the former police station compound.

The air smelled sweetly of cordite, sawdust, blood and diesel leaking from the portable generator. Now that the rescue portion of the job was over the scene was filled with white boiler-suited forensic officers gathering material and taking photographs.

I found the chief investigating officer and introduced myself.

“Detective Inspector Duffy, Carrick RUC,” I said.

“Detective Chief Superintendent McClure, Special Branch,” he said and offered his hand. I shook it. His handshake was even limper than mine. We were both exhausted. He was a grizzled man with a grey moustache and black eyebrows. About fifty. He favoured his left hand side and was smoking a little cigar.

“You were up there on traffic duty?” he asked in a faint Scottish accent.

“Aye.”

“They’ve got a detective inspector on bloody traffic duty? What’s the bloody world coming to?”

“I suppose they’re a bit short-handed. Apparently the army units they were going to deploy in East Antrim are off to the Falklands,” I said.

He spat. “Fucking Falklands. Fucking sheep. That’s all that’s there. I know, I’ve been. Military Police. You’re not the Duffy that Tony McIlroy’s always going on about, are you?” McClure asked.

“Tony talks about me?”

“He said we should recruit you for Special Branch, he says that you’re good.”

“That’s nice of him.”

“Can’t stand the man myself. Very showy.”

“When we arrived last night somebody told us that this is some new IRA technique?” I asked, to change the subject.

“Oh, yes. Come and see.”

He lifted the “RUC: Do Not Cross” tape and I followed him across the site of the former police station. He showed me where the lorry had driven through the police station’s barrier and then exploded. “It’s a very impressive new technique,” he said. “We’ll have to re-evaluate security at every barracks in Ulster. Apparently the man who drove the lorry was forced to do it. His family had been taken hostage by the IRA and he was told that if he didn’t drive the vehicle right into the station they’d all be shot. As soon as he breached the barrier another IRA team blew up the lorry by remote control. As you can see it was a big bomb. A thousand pounds, maybe.”

“You’ve seen this sort of thing before?”

“Once before. Two makes it a pattern. It’s a pretty devastating new ploy. Between us, Inspector, the higher ups are keeking their whips.”

“I’ll bet they are. Every police station in Ulster will be vulnerable.”

“Aye.”

“What about the guy who drove the lorry? Was he a copper too?”

“No. Catholic bread-van driver. He delivered to the peelers so they’re calling him a ‘collaborator’. He delivers bread for a living and he’s a collaborator. That’s the world we’re living in, Inspector.”

We walked among the smoking debris and the Chief Superintendent picked up the twisted remains of a steering wheel. “Look at this,” he said, showing me the plastic wheel which had been warped and melted into an amazing spaghetti sculpture. I noticed a bent ring of metal around the wheel. “They didn’t trust him completely, did they?” I said, pointing at the metal ring.
