“But then Margot examined him,” said Strike.

“But then,” repeated Janice slowly, nodding, “that hoity-toity bitch takes ’im into ’er surgery and examines ’im. And I knew she was suspicious. She asked me after, what drinks it was I’d given ’im, because the little bastard ’ad told ’er Mummy was givin’ ’im special drinks…

“Not a week later,” said Janice, twisting the old wedding ring on her finger, “I realize Steve’s going to see ’er about ’is ’ealf, instead of coming to see me. Next fing I know, Margot’s asking me all about Joanna’s death, out the back by the kettle, and Dorothy and Gloria were listening in. I said, ‘ ’Ow the ’ell should I know what ’appened?’ but I was worried. I fort, what’s Steve been telling ’er? ’As ’e said ’e finks there was somefing wrong wiv it? ’As someone said they saw a nurse leaving the ’ouse?

“I was getting worried. I sent ’er chocolates full of phenobarbital. Irene ’ad told me Margot ’ad ’ad freatening notes, and I’m not surprised, interfering bitch, she was… I fort, they’ll fink it’s ’ooever sent them notes, sent the chocolates…

“But she never ate ’em. She frew ’em in the bin in front of me, but after, I ’eard she’d taken ’em out the bin and kept ’em. And that’s when I knew, I really knew. I fort, she’s gonna get ’em tested…”

“And that’s when you finally agreed to go on a date with simple old Larry,” said Strike.

“’Oo says ’e was simple?” said Janice, firing up.

“Irene,” said Strike. “You needed access to concrete, didn’t you? Didn’t want to be seen buying it, I’d imagine. What did you do, tell Larry to take some and not mention it to anyone?”

She simply looked at him out of those round blue eyes that nobody who hadn’t heard this conversation could possibly mistrust.

“What gave you the idea of concrete?” Strike asked. “That rumor of the body in the foundations?”

“Yeah,” said Janice, finally. “It seemed like the way to stop the body smelling. I needed ’er to disappear. It was too near ’ome, what wiv ’er examining Kev, and asking me about Joanna, and keeping those chocolates. I wanted people to fink maybe the Essex Butcher got ’er, or the bloke ’oo sent the threatening notes.”

“How many times had you visited the Athorns before you killed Margot?”

“A few.”

“Because they needed a nurse? Or for some other reason?”

The longest pause yet ensued, long enough for the sun to slide out from a cloud, and the glass Cinderella coach to burn briefly like white fire, and then turn back into the tawdry gewgaw it really was.

“I sort of fort of killing them,” said Janice slowly. “I don’t know why, really. Just from the time I met ’em… they were odd and nobody ever went there. Those cousins of theirs visited once every ten years. I met ’em back in January, those cousins, when the flat needed cleaning out, to stop that man downstairs going to court… they stayed an hour and let ‘Clare’ do all the rest…

“Yeah, I just fort I might kill the Athorns one day,” she said, with a shrug. “That’s why I kept visiting. I liked the idea of watching an ’ole family die togevver, and waiting to see when people realized, and then it’d be on the news, probably, and I’d know what ’appened when everyone was gossiping, local…

“I did a bit of experimenting on ’em. Vitamin injections, I told them it was. Special treatments. And I used to hold their noses while they were asleep. Used to pull up their eyelids and look at their eyes, while they were unconscious. Nurses don’t never give anesthetics, see, but Dr. Brenner was letting me ’ave all sorts, and the Athorns just let me do stuff to ’em, even Gwilherm. ’E loved me coming over. ’E’d spend days on benzedrine and then ’e’d get sedatives off me. Proper junkie.

“I used to say to ’im, now, don’t you go telling anyone what we’re doing. These are expensive treatments. It’s only because I like your family.

“Some days, I used to fink, I’ll kill the kid and then give evidence against Gwilherm. That was one idea I ’ad. I fort, I’ll get in the papers, all dressed up, give evidence against ’im, you know. My picture on the front page… and I fort that’d be somefing interesting to talk to Steve about, when ’e seen my picture in the paper. Men love nurses. That was the on’y fing I ’ad going for me when I was out wiv Irene, and then the bitch starts pretending she’s a nurse an’ all…

“Only fank Gawd I never did any of that, fank Gawd I saved the Athorns, because what would I ’ave done wiv Margot if I ’adn’t ’ad them up the road? I’d nicked their spare key by then. They never noticed.

“I never fort it would work,” said Janice, “’cause I ’ad to frow the plan togevver in about five minutes. I knew she was onto me, when she saved the chocolates, and I was up all night, finking, worrying… and it was the next day, or maybe the day after, Steve went charging out of her surgery that last time. I was scared she’d warned ’im about me, because when I went round that night, ’e made some excuse not to let me in… I mean, ’e never went to the police, so now I know I was being paranoid, but at the time—”

“You weren’t being paranoid,” said Strike. “I spoke to him yesterday. Margot told him he ought to stop eating anything you prepared him. Just that. He understood what she was saying, though.”

Janice’s face grew redder.

“That bitch,” she said venomously. “What did she do that for? She ’ad a rich ’usband and a lover wanting her back, why’s she got to take Steve off me?”

“Go on,” said Strike, “about how you did it.”

A subtle change now came over Janice. Previously, she’d seemed diffident, matter-of-fact, or even ashamed of her own impetuousness, but now, for the first time, she seemed to enjoy what she was saying, as though she killed Margot Bamborough all over again, in the telling.

“Went out wiv Larry. Told ’im some bullshit about this poor family what needed to concrete over somefing on their roof terrace. Said they were dirt-poor. ’E was so keen to impress me, silly sod, ’e wanted to go do the building work for ’em.”

She rolled her eyes.

“I ’ad to give ’im all this crap about ’ow that would made the dad feel inadequate… I said just nicking a few bags of concrete mix off the building site’d be enough.

“Larry drove it to Albemarle Way for me and carried it up to their landing. I wouldn’t let ’im come any further, said it would be uneffical for ’im to see patients. ’E was silly, Larry, you could tell ’im anyfing… But he wouldn’t marry me,” said Janice suddenly. “Why is that? Why wouldn’t anyone marry me? What ’aven’t I got, that ovver women ’ave?” asked the nurse who’d pulled back the eyelids from her drugged victims to stare into their unseeing eyes. “Nobody ever wanted to marry me… never… I wanted to be in the paper in a white dress. I wanted my day in church and I never got it. Never…”

“You needed an alibi as well as concrete, presumably?” said Strike, ignoring her question. “I assume you chose the demented old lady in Gopsall Street because she couldn’t say one way or another whether you’d been with her when Margot disappeared?”

“Yeah,” said Janice, returning to her story, “I went to see ’er late morning and I left drugs there and a note, to prove I’d been in. I knew she’d agree I was there early evening. She didn’t ’ave no family, she’d agree with anyfing you said to ’er…

“I went from ’er place to buy a cinema ticket for the late-night show, and I called up my babysitter and told ’er I’d be later than I fort because we were getting the last viewing. I knew Irene wouldn’t wanna go wiv me. She’d been makin’ noises about not feelin’ up to it all morning. I knew she didn’t ’ave no bad toof, but I pretended to go along wiv it. Irene never wanted to go anywhere we weren’t gonna meet men.”

“So, you went back to the surgery that afternoon—in through the back door, I suppose?”

“Yeah,” said Janice, her eyes slightly unfocused now. “Nobody saw me. I knew Margot ’ad a doughnut in the fridge, because I’d been in there that morning and seen it, but there was people around all the time, so I couldn’t do nuffing. I injected it wiv Nembutal sodium solution, froo the cellophane.”

“You must’ve been well practiced by now? You knew how much to give her, so she could still walk up the road?”
