“Where’s your rush?” Ma demanded. “Sit down there.”

“Business before pleasure. Where’s the case?”

Shay nodded to the floor at his feet. “All yours,” he said. Jackie sat down again with a thump. I picked my way around the coffee table and the sofa and the chairs, under all those eyes.

The suitcase was by the window. It was a pale-blue thing with rounded corners, spotted over with big patches of black mold, and it was a crack open; someone had forced the pathetic tin locks. What got to me was how small it was. Olivia used to pack just about everything we owned, including the electric kettle, for a weekend away. Rosie had been heading for a whole new life with something she could carry one-handed.

I asked, “Who’s touched this?”

Shay laughed, a hard sound at the back of his throat. “Jaysus, lads, it’s Columbo. Are you going to take our fingerprints?”

Shay is dark and wiry and restless, and I’d forgotten what it was like, getting too near him. It’s like standing next to a power line; it makes you edgy all over. He had sharp fierce grooves going from nose to mouth, these days, and between his eyebrows. “Only if you ask me nicely,” I said. “Did you all touch it?”

“I wouldn’t go near it,” Carmel said promptly, doing a little shudder. “The dirt of it.” I caught Kevin’s eye. For a second it was like I’d never been away.

“Me and your da tried opening it,” Ma said, “only it was locked, so I called Shay down and I got him to take a screwdriver to it. We’d no choice, sure; there was nothing on the outside to tell us who owned it.”

She gave me a belligerent look. “Dead right,” I said.

“When we saw what was in it… I’m telling you, I got the shock of my life. The heart was leaping out of me; I thought I was having a heart attack. I said to Carmel, thank God you’re here with the car, in case you’ve to bring me to the hospital.” The look in Ma’s eye said this would have been my fault, even if she hadn’t figured out how yet.

Carmel told me, “Trevor doesn’t mind giving the children their tea, not when it’s an emergency. He’s great that way.”

“Me and Kevin both had a look inside once we got here,” Jackie said. “We touched bits, I don’t remember what ones-”

“Got your fingerprint powder?” Shay inquired. He was slouching against the window frame and watching me, eyes half closed.

“Some other day, if you’re a good boy.” I found my surgical gloves in my jacket pocket and put them on. Da started to laugh, a deep, nasty rasp; it collapsed into a helpless coughing fit that shook his whole chair.

Shay’s screwdriver was on the floor beside the suitcase. I knelt down and used it to lift the lid. Two of the boys in the Tech Bureau owed me favors, and a couple of the lovely ladies fancied me; any of them would run a few tests for me on the QT, but they would appreciate me not fucking up the evidence any more than I had to.

The case was stuffed with a heavy tangle of fabric, stained black and half-shredded with mold and age. A dark, strong smell, like wet earth, came up off it. That undercurrent I’d caught in the air, when I first came in.

I lifted things out slowly, one by one, and stacked them in the lid where they wouldn’t get contaminated. One pair of baggy blue jeans, with plaid patches sewn under the rips in the knees. One green woolen pullover. One pair of blue jeans so tight they had zips at the ankles, and Jesus Almighty I knew them, the swing of Rosie’s hips in them punched me right in the gut. I kept moving and didn’t blink. One man’s collarless flannel shirt, fine blue stripes on what used to be cream. Six pairs of white cotton knickers. One long-tailed purple and blue paisley shirt, falling to pieces, and when I picked it up the birth cert fell out.

“There,” Jackie said. She was leaning over the arm of the sofa, peering anxiously at me. “See? Up until then, we thought it might’ve been nothing, I don’t know, kids messing or someone who’d robbed some gear and needed to hide it, or maybe some poor woman whose fella was hurting her and she was keeping her things ready for when she got the courage to leave him, you know how they tell you to do in the magazines?” She was starting to rev up again.

Rose Bernadette Daly, born 30 July 1966. The paper was on the verge of disintegrating. “Yep,” I said. “If that’s kids messing, they’re pretty thorough about it.”

One U2 T-shirt, probably worth hundreds, if it hadn’t been pockmarked with rot. One blue-and-white-striped T-shirt. One man’s black waistcoat; the Annie Hall look was in then. One purple woolen pullover. One pale-blue plastic rosary. Two white cotton bras. One off-brand Walkman that I spent months saving for; I got the last two quid a week before her eighteenth birthday, by helping Beaker Murray sell bootleg videos down at the Iveagh Market. One spray can of Sure deodorant. A dozen home-taped cassettes, and I could still read her round handwriting on some of the inserts: REM, Murmur; U2, Boy; Thin Lizzy, the Boomtown Rats, the Stranglers, Nick Cave and the Bad Seeds. Rosie could leave everything else behind, but her record collection was coming with her.

At the bottom of the case was a brown envelope. The bits of paper inside had been mashed into a solid lump by twenty-two years’ worth of damp; when I pulled delicately at the edge, it came apart like wet jacks roll. One more favor for the Bureau. A few blurred words of type still showed through the plastic window in the front of the envelope.

… LAOGHAIRE-HOLYHEAD… DEPARTING…:30AM… Wherever Rosie had gone, she had got there without our ferry tickets.

Everyone was staring at me. Kevin looked genuinely upset. “Well,” I said. “That appears to be Rosie Daly’s suitcase, all right.” I started to transfer stuff from the lid back into the case, leaving the papers till last so they wouldn’t get crushed.

“Will we call the Guards?” Carmel asked. Da cleared his throat, spectacularly, like he was going to spit; Ma shot him a ferocious look.

I asked, “And say what?”

Clearly no one had thought about this. “Someone stuck a suitcase behind a fireplace, twenty-odd years ago,” I said. “It’s hardly the crime of the century. The Dalys can ring the Guards if they want, but I’m warning you now, I wouldn’t expect them to bring out the big guns for the Case of the Blocked Chimney.”

“But Rosie, sure,” Jackie said. She was tugging at a piece of hair and gazing at me, all bunny-teeth and big worried blue eyes. “She’s missing. And that yoke there, that’s a clue, or evidence, or whatever you call it. Should we not…?”

“Was she reported missing?”

Glances back and forth: nobody knew. I seriously doubted it. In the Liberties, cops are like the jellyfish in Pacman: they’re part of the game, you get good at avoiding them, and you definitely don’t go looking for them. “If she wasn’t,” I said, shutting the case with my fingertips, “it’s a little late now.”

“But,” Jackie said. “Hang on. Does this not look like…? You know. Like she didn’t go off to England after all. Does it not seem like maybe someone might have…?”

“What Jackie’s trying to say here,” Shay told me, “is it looks like someone knocked Rosie off, shoved her in a bin liner, hauled her round to the piggeries, dumped her in, and put that case up a fireplace to get it out of the way.”

“Seamus Mackey! God bless us!” from Ma. Carmel crossed herself.

This possibility had already occurred to me. “Could be,” I said, “sure. Or she could have been abducted by aliens and dropped off in Kentucky by mistake. Personally, I’d go for the simplest explanation, which is that she stuck that case up the chimney herself, didn’t get a chance to take it back out, and headed over to England without a change of undies. But if you need a little extra drama in your life, feel free.”

“Right,” said Shay. There are plenty of things wrong with Shay, but stupid isn’t one of them. “And that’s why you need that shite”-the gloves, which I was stuffing back into my jacket. “Because you don’t think there’s any crime here.”
