“None taken, I assure you.”

They came up on us fast. But a transit is a transit and a police car is only a police car. We had one of them off the road at the roundabout and another into a row of parked cars soon after. Which left us only the helicopter.

“It’s a helicopter!” shouted Dave. “We’ll never be able to lose that.”

“To the nearest underground station,” I said. “We’ll take the tube.”

“But we need a van for the booty.”

“We’ll improvise when the time comes. To the nearest tube station, Sandra, and step on it.”

“Yes, Masser Gary,” said Sandra, bless her little heart. Charred though it was, in a burned-out cab in Chiswick.

Now happily for us, the nearest tube station was Earls Court. And since there are loads of different lines that run through Earls Court, the police wouldn’t know which one we were getting on. So they wouldn’t know which train to shut down in which tunnel. Which meant we were safe for now.

“Three singles to Mornington Crescent,” said Dave to the chap in the ticket office.

“Get real,” said the chap.

“Excuse me?” said Dave.

“Three singles to Mornington Crescent. Do I look like a complete twonker?”

“Yes,” said Dave. “But what has that got to do with anything?”

“It has to do with the fact that Mornington Crescent station is closed for repairs.”

“Oh,” said Dave. “Since when?”

“Since 1945.”

“You blokes on the transport don’t rush yourselves with repairs, do you?”

“We’re very thorough. We have the public’s safety always in the forefront of our minds.”

“OK,” said Dave, “what line is Mornington Crescent on?”

“The Northern line,” said the chap.

“And what’s the nearest station to it, on that line?”

“Euston,” said the chap.

“Three singles to there, then.”

“Righty right,” said the chap. “But just one thing.”

“Yes?” said Dave.

“The woman with you, the one with the wonky head that doesn’t seem to match her body …”

“What about her?” asked Dave.

“Why is she stark bollard naked?” asked the chap.

“She’s a naturist,” said Dave. And he paid up for the tickets.

Yes, well, I suppose that I should have had Dave nick some clothes for Sandra when he nicked some trousers for me from the fashionable boutique. But I can’t be expected to think of everything.

I must confess that we didn’t exactly blend in with all the other commuters. People kept looking at Sandra.

And, frankly, I found that rather offensive. Blokes eyeing up my missus. I felt that I should take issue with them. Possibly make an example of one.

“Don’t,” said Dave, who apparently read my mind. “We’ll change from the District line at Embankment. Then we’ll travel with the driver.”

“Do they let you do that?” I asked.

“No,” said Dave. “But we’ll sort it.”

At Embankment, we changed onto the Northern line. We got into the first carriage and Dave knocked on the driver’s door. “Inspector!” called Dave. “Could I have a word?”

The driver opened the door. We pushed our way into his cab.

“Get out!” shouted the driver. “You’re not allowed in here.”

“Deal with the driver, Gary,” said Dave.

“Aaagh!” went the driver. “It’s Cheese the psycho killer. I saw you on TV.”

I dealt sternly with that driver. And then I turned to Dave. “He recognized me,” I said.

“That’s hardly surprising,” said Dave.

“Yeah, but no one else on the trains we’ve been on seemed to recognize me. How do you account for that?”

“I think Sandra might have distracted them.”

“Oh yeah. So what are we going to do now?”

“You’re going to drive the train and stop it at Mornington Crescent.”

“But I don’t know how to drive a train.”

“Sandra know,” said Sandra.

“You do?” I said.

“All middle-class girls taught how to drive trains at prep school,” said Sandra.

“Eh?” said I.

“In case society collapse. If revolution come. All middle-class girls taught everything. How to drive trains, run power stations, run government, everything.”

“I didn’t know this,” I said.

“That because you working class. Working class know nothing. Get taught nothing at school. Kept ignorant, kept under control.”

“This is a bit of a revelation,” I said.

“It doesn’t surprise me,” said Dave. “Mr Trubshaw told me all about this conspiracy-theory stuff in Strangeways. He said nothing in society is actually what it seems. The whole thing is a big con.”

“I’d like to hear more,” I said, “but the commuters will soon be banging on the door demanding to know why the train isn’t moving.”

“You don’t travel much on the tube, do you, Gary?” said Dave.

“No,” I said, shaking my head, and wiping the driver’s blood from my hands.

“Well, trust me, the commuters won’t notice any difference. Now, Sandra, drive the train to Mornington Crescent.”

“I’ll tell her,” I said. And I told her.

There was something altogether weird about Mornington Crescent. As Sandra drew the train to a halt, Dave and I stared out at it. The lights were on, but no one was at home. Nor, it seemed, had anyone been home since the end of the Second World War. There were all these wartime war-effort posters on the walls, and others for Bovril and Bisto and Doveston’s steam-driven wonder beds.

“What about the commuters?” I asked Dave. “We can’t let them all out here.”

“We’ll leave through the driver’s door, directly onto the platform,” said Dave. “Why not stick the driver’s hand down on the deadman’s handle and send the train on to other parts?”

“But it might crash,” I said.

Dave raised an eyebrow to me.

“Sorry,” I said. “I don’t know what came over me there.”

We got out of the driver’s door, I dumped all of the driver down on the deadman’s handle and Sandra set the train back in motion. And we watched as the train gathered speed and left the station.

“There,” said Dave. “Job done.”

“You’re pretty quick on your feet, aren’t you?” I said to Dave.

“Have to be,” said Dave. “In my business, you always have to be thinking one step ahead.”

“If you’re so smart,” I said, “how come you’re always getting caught?”

“Because,” said Dave, “I may be smart, but there’s always someone smarter. In my case it’s Inspectre Hovis of Scotland. And that’s now in your case too. So if we wish to outsmart him, we should both get on with the business at hand, rather than stand around here making chitchat.”

“Lead on, Dave,” said I. “Take us to the booty.”

“Yeah, well, I don’t exactly know the way from here. I sort of knew the way from a secret tunnel that Churchill told me about, but I don’t think it’s anywhere around here. We’ll have to work this out together.”

“Fair enough,” I said. “At least the lights are on. Let’s go and explore.”

So we went and explored.

Mornington Crescent didn’t smell too good. It smelled musty and lifeless, as if no one had breathed the air there for years. Nor was supposed to.

“It feels really odd here,” said Dave, as we wandered down the big tiled corridors. “Unworldly. Do you know what I mean?”

I nodded. And I remembered too. All this reminded me of something. Something I’d felt a long time before. “It’s like those crypts,” I said. “The ones I used to crawl into in the graveyard when I was a child. They felt like this. Like you weren’t supposed to be in them. Which you weren’t.”

“Station dead,” said Sandra. “All dead here. Sandra know, Sandra dead too.”

“Don’t go putting yourself down,” said Dave. “You’re more alive than half the people I know.”

“Thank you, Dave,” said Sandra. “Sandra love Masser Dave.”

“What was that?” I asked.

“Sandra say, ‘Sandra love Masser Gary,’” said Sandra.

“Hm,” said I.

“There’s a light up ahead,” said Dave. “Big light. Big something, by the look of it.”
