I said, “One last thing.” I fished in my jacket, pulled out a bunch of envelopes just big enough to hold a snapshot, and handed out three of them. “Do any of you recognize this woman?”

The Dalys gave it their best shot, but no hundred-watt bulbs lit up, presumably because Fingerprint Fifi is a high-school algebra teacher from Nebraska whose photo I pulled off the internet. Wherever I go, Fifi goes. Her picture has a nice wide white border so you won’t feel the need to hold it delicately by the edges, and since she may be the most nondescript human being on the planet, it’ll take you a close look-probably involving both thumbs and index fingers-to be sure that you don’t know her. I owe my girl Fifi many a subtle ID. Today, she was going to help me find out whether the Dalys had left prints on that suitcase.

What had my antennae wiggling at this lot was the mind-bending off chance that Rosie had been heading to meet me, after all. If she was sticking to our plan, if she didn’t need to dodge me, she would have taken the same route I had: out the door of the flat, down the stairs, straight into the Place. But I had had a perfect view of every inch of the road, the whole night through, and that front door had never opened.

Back then, the Dalys had the middle floor of Number 3. On the top floor were the Harrison sisters, three ancient, easily overexcited spinsters who gave you bread and sugar if you did their messages for them; the basement was sad, sick little Veronica Crotty, who said her husband was a traveling salesman, and her sad, sick little kid. In other words, if someone had intercepted Rosie on her way to our rendezvous, that someone was sitting across the coffee table from me and Kevin.

All three of the Dalys looked genuinely shocked and upset, but that can swing so many ways. Nora had been a big kid at a difficult age, Mrs. Daly was somewhere on the crazy spectrum, and Mr. Daly had a five-star temper, a five-star problem with me, and muscles. Rosie was no lightweight; her da might not be Arnie after all, but he had been the only one in that house strong enough to dispose of her body.

Mrs. Daly asked, peering anxiously over the photo, “Who’s she, now? I’ve never seen her about. Do you think she might have hurt our Rosie? She looks awful small for that, does she not? Rosie was a strong girl, she wouldn’t-”

“I’d say she has nothing to do with it,” I told her truthfully, retrieving the photo envelopes and slipping them back into my pocket, in order. “I’m just exploring every possibility.”

Nora said, “But you think someone hurt her.”

“It’s too early to assume that,” I said. “I’ll set some inquiries in motion and keep you posted. I think I’ve got enough to start with. Thanks for your time.” Kevin leaped out of his seat like he was on springs.

I took off my gloves to shake their hands good-bye. I didn’t ask for phone numbers-no sense in pushing my welcome-and I didn’t ask if they still had the note. The thought of seeing it again made my jaw clench.

Mr. Daly walked us out. At the door he said abruptly, to me, “When she never wrote, we thought it was you that wouldn’t let her.”

This could have been some form of apology, or just one final dig. “Rosie never let anyone stop her from doing what she wanted to do,” I said. “I’ll get back to you as soon as I have any information.” As he closed the door behind us, I heard one of the women starting to cry.

The rain had slackened off to a faint damp haze, but the clouds were getting denser and darker; there was more on the way. Ma was pressed up against the front-room window, sending out curiosity rays that practically burned my eyebrows off. When she saw me looking in her direction, she whipped up a J-cloth and started furiously cleaning the glass.

“Nicely done,” I said to Kevin. “I appreciate that.”

He shot me a quick sideways glance. “That was weird.”

His own big brother, the same one who used to nick crisps from the shop for him, in full cop mode. “Didn’t show,” I told him approvingly. “You worked it like a pro. You’ve got a knack for this, do you know that?”

He shrugged. “Now what?”

“I’m going to put this in my car before Matt Daly has a change of heart,” I said, balancing the case on one arm and giving Ma a wave and a big grin, “and then I’m going to go have a little chat with someone I used to know. Meanwhile, you’re going to wrangle Ma and Da for me.”

Kevin’s eyes widened in horror. “Ah, Jaysus, no. No way. She’ll still be raging about the breakfast.”

“Come on, Kev. Tighten up your jockstrap and take one for the team.”

“Team, my arse. You’re the one pissed her off to begin with, and now you want me to go back in there and take all the flak?”

His hair was sticking up with outrage. “Bingo,” I said. “I don’t want her hassling the Dalys, and I don’t want her spreading the word, at least not right away. All I need is an hour or so before she starts doing damage. Can you give me that?”

“What am I supposed to do if she starts heading out? Rugby-tackle her?”

“What’s your phone number?” I found my mobile, the one my boys and my informants use, and sent Kev a text that said HI. “There,” I said. “If Ma escapes, you just reply to that and I’ll come rugby-tackle her myself. Fair enough?”

“Fucking hell,” Kevin muttered, staring up at the window.

“Nice one,” I said, clapping him on the back. “You’re a trooper. I’ll meet you back here in an hour and I’ll get you a few pints tonight, how’s that?”

“I’ll need more than a few,” Kev said gloomily, and he squared up his shoulders and headed off to face the firing squad.

I stashed the suitcase safely in the boot of my car, ready to take to a lovely lady in the Technical Bureau whose home address I happened to know. A handful of ten-year-olds with underprivileged hair and no eyebrows were slouched on a wall, scoping out the cars and thinking wire hangers. All I needed was to come back and find that suitcase gone. I leaned my arse on the boot, labeled my Fingerprint Fifi envelopes, had a smoke, and stared our country’s future out of it until the situation was clear all round and they fucked off to vandalize someone who wouldn’t come looking for them.

The Dalys’ flat had been the mirror image of ours; there was nowhere to stash a body, at least not long-term. If Rosie had died in that flat, then the Dalys had had two options. Assuming Mr. Daly was the proud owner of one serious set of cojones, which I didn’t rule out, he could have wrapped her up in something and carried her out the front door and away: into the river, onto some abandoned site, into the piggeries as per Shay’s charming suggestion. But, the Liberties being the Liberties, the odds were high that someone would have seen it, remembered it, and talked about it. Mr. Daly didn’t strike me as a gambling man.

The nongambler’s option was the back garden. Probably nowadays half the gardens had been dolled up with shrubs and decking and various wrought-iron doodads, but back then they were neglected and ragged: scrawny grass, dirt, boards and broken furniture and the odd wrecked bike. Nobody went out there except to use the toilet or, in summer, to hang washing; all the action was out front, in the street. It had been cold, but not cold enough to freeze the ground. An hour one night to start digging a grave, maybe another hour the next night to finish it, another the third night to fill it in. No one would spot you; the gardens didn’t have lighting, on dark nights you needed a torch just to find your way to the jacks. No one would hear you; the Harrison sisters were deaf as a pair of fence posts, the back windows of Veronica Crotty’s basement were boarded up to keep the heat in, everyone else’s windows would have been shut tight against the December cold. Cover the grave, during the days and when you were all finished, with a sheet of corrugated iron or an old table or whatever was lying around. No one would look twice.
