But in the silence before we broke in, a faint sound reached us. A man's voice, muffled by brick and glass and layers of filth. He was singing: "Baby, You're Out of Time". So was he.
McCann crashed through the back door, and five of us followed him. The rest waited outside. Our torches made crazy snapshots of the interior: rotting wallpaper, a cracked ceiling, broken chairs. Some new-looking food cartons, bottles and candles on a table were the only sign of occupancy. In all probability, this place had never had electricity.
The singing continued in one of the upstairs rooms. Was it a tape recorder? What kind of trap were we walking into?
On the staircase, my foot went through a rotten step and I fell, cursing. When I got up I was alone on the stairs. Ahead of me was only the song. The blues.
Apart from police, there was only one man in the upper room. He was kneeling on a filthy mattress, in front of a small suitcase. The lid was up. The suitcase was full of jewels: pearls, rubies, silver, emeralds. Some were strung or inlaid, some were loose. He was running his hands through them, and singing to himself.
His hair was knotted and filthy; his once-white shirt was streaked with filth and sweat. He didn't look away from his hoard or stop singing, even when McCann clamped the handcuffs on his wrists.
We kept him at the Green Lane station for a week.
His name was Jason Welles, and he was a member of the Stoke gang. An experienced fence, despite being only twenty. Among the station officers he was known as "Mr Pitiful" — and not only because of the singing.
For two days he did nothing but complain that we'd taken his jewels from him, because "She won't come to me if I don't have them. She's an old-fashioned girl. No gifts, no loving." His eyes were a pale, tormented blue.
One night, when I took him his dinner, he remarked to me as calmly as if we'd been talking about her all evening: "That first time, she came out of the wall. Plaster clinging to her like a shroud. I was holding an emerald bracelet, trying to judge its value. She stood there naked and reached out for it. Then she took me into the garden and showed me where her family live.
"I wanted to stay with her, but she said it wasn't time yet. When will it be time?" The last question was asked as if everyone knew the answer but him. I didn't know what to say.
Every attempt to interview him produced the same story. He lived in a twilight world of ghosts and angels, a delusional shell that could have made him a cult leader if he'd had a better haircut.
It seemed likely that the gang's adolescent games with drugs and prostitutes had triggered some kind of buried madness in him. Or else there'd been some hallucinogen in the moulds and lichens that decorated the ruined Aldridge house.
A search of those houses and the surrounding waste ground had yielded no trace of the other gang members. If he didn't tell us where they were, we'd probably never find out.
But how do you interrogate a madman?
I attended three of the interview sessions. Each time, he sang to himself and muttered random nonsense, ignoring our questions. To be fair, we ignored his. His world and ours rarely seemed to touch.
Typically, he'd rock in his chair and run his hands through imaginary jewels — or through the hair of an imaginary woman. He'd sing "Out of Time" or "I Can't Help Myself", then start talking suddenly, as if resuming a conversation we'd interrupted.
The interview tapes and transcripts are doubtless long since thrown away, but I can remember some of his words…
"As soon as I saw the house, I knew it belonged to a family. A real family, not like my mum and her boyfriends after my dad went to prison. Nathan, Mark and Rich, they brought call girls into the house, but I knew the family wouldn't like that.
"Then she came to me one night. Wearing a gown of rotting wallpaper that fell from her, and her body glowed brighter than a candle.
"She showed me where her family sleep under the water. And the thin grey tubes they breathe through, like a baby's umbilical cord.
"I gave her jewels to wear in her long dark hair. To hang in the tunnels under the ground.
"The other three guys… well, they were just thieves. They had no idea what anything was worth. It was just money to them. Money to spend on cars and clothes and cunt. I let her family take them." He giggled like a child. "Not much left of them after a while.
"Poetic justice. What they had was stolen. But she never stole from me. I gave her everything. I opened her and wrapped her around me.
"They say when you come off, it never lasts. But I know how to make it last forever.
"Then the morning comes, and she's gone. Baby, you're out of time… Where are my jewels? The earrings, the bracelets, the necklaces. I need them to give to her. Why have you taken them from me?" He stared angrily at McCann and me. We said nothing. "She can't reach me here. It's too far from the water. You're out of touch, my baby…
"Why don't you let her find me? Why'd you put me in a cell with no plaster or wallpaper, so she can't get through? I've nothing to give her now but myself. Why do you always have to break up the family?"
We weren't getting anything useful from him. And he was a liability as a prisoner. He yelled, kicked at the door, wet the bed, needed a suicide watch. We were glad to get rid of him.
The Stoke police thought he was probably unfit to stand trial, but he'd be on a section for quite a while anyway. It was hard to imagine him getting involved in organized crime. He couldn't even feed himself.
While Jason Welles was dreaming in a secure unit somewhere near Stoke, I took my annual leave.
I'd been going out with a girl called Joanna since the previous year, and this was our first holiday together; a self-catering week in Dorset.
The days were close and rainy, so we spent a lot of time in bed. I kept dreaming about Welles reaching up for something he couldn't touch, saying I opened her and wrapped her around me. His obsession had convinced me there was something dangerous about love. We split up not long after we came back to Walsall.
Joanna came from Blackheath, and had a rather bleak sense of humour. That was something we shared. She used to repeat bits of Dolly Allen monologues, an elderly comedienne who was well known in the Black Country at that time. Like the story about the vacuum cleaner salesman: I opened the door, this young fellow in a suit was stood there. He poured a little bag of dirt onto my hall carpet and said "If my vacuum cleaner can't get that dust out of your carpet in one minute, I'll eat the dust." I said, "Here's a spoon, there's no electric in this house."
One day when the sky was clear, we went for a walk inland. The footpath took us through an abandoned farm. The old farmhouse was in ruins, its roof-beams open to the sky. The sun was burning and we needed shelter, so we slipped into the barn.
Gaps in the roof showed where the rain had got in and rotted the bundles of hay. Something moved at the edge of my vision — a snake or a mouse. Joanna turned to me and we kissed hungrily in the shadows. We made love with some violence, our fingernails and teeth leaving marks in each other. Afterwards, we struggled for breath and held each other more tenderly than we had all week.
At that moment, I recognized the cold fever-smell of stagnant water. Looking over Joanna's shoulder, I saw a barrel standing behind the haystack we'd used as a bed. It was nearly full of water.
In the dim light, I could just see a number of pale tubes hanging down from the water surface. But I couldn't see what they were connected to. I reached over and let my fingertips brush the water. At once, the tubes convulsed. They were connected to long, translucent maggots that jerked in the water. My finger touched one of them. I threw myself backwards and stood there, breathing hard and trying not to vomit.
