She finally said, "It's such a leap, Thomas. There's too much to account for. He's been alibied - "
"McHaggis could be lying. She could also be mistaken. She says he was home taking a shower but that's what he always did, didn't he? She was asked days later, Isabelle, and she could well want to protect him anyway."
"Why?"
"She's a woman."
"Oh, for God's sake, what's that supposed to - "
"Everyone agrees he has a way with women. Why not with Bella McHaggis as well?"
"What, then? He's sleeping with her? With her, with Jemima, with ...who else, Thomas?"
"With Gina Dickens, I dare say."
She stared at him. "Gina Dickens?"
"Think about it. There she is in the magazine pictures of the Portrait Gallery's opening show. If Frazer was there - and we know he was - how impossible is it to believe he met Gina Dickens that night? How impossible is it to believe that, meeting Gina Dickens, he fell for her?
Wanted to add her to his list of conquests? Ultimately decided to replace Jemima with her? Sent her down to Hampshire to get herself involved with Jossie so that - "
"D'you realise how many things are unaccounted for in all of this?" She put her head in her hands. Her brain felt sodden. "We can suppose this and suppose that, Thomas, but we have no evidence that anything you're saying actually happened, so what's the point?"
Lynley went on, seeming undeterred. They did have evidence, he pointed out, but he reckoned they hadn't been putting it together correctly.
"What, for example?"
"The handbag and the bloodstained shirt from the Oxfam bin, just to begin," he said.
"We've assumed someone planted them there to implicate one of the inhabitants of Bella McHaggis's house. We haven't considered that, knowing the bin wasn't emptied regularly, one of the inhabitants of the house put the items there merely to store them."
"Store them?"
"Until they could be taken down to Hampshire, handed over to Gina Dickens, and placed somewhere on Gordon Jossie's property."
"God. This is madness. Why wouldn't he just - "
"Listen." Lynley returned to the table and sat. He leaned across it and put his hand over her arm. "Isabelle, it's not as mad as it seems. This crime depended upon two things. First, the killer had to have knowledge of Jemima's past, her present, and her intentions towards Gordon Jossie. Second, the killer couldn't have worked alone."
"Whyever not?"
"Because he had to gather what evidence was going to be necessary to frame Gordon Jossie for this murder and that evidence was to be found in Hampshire: the murder weapon and a yellow shirt from Jossie's clothes cupboard, I expect. At the same time the killer had to know what Jemima was doing with regard to Jossie. If Frazer was indeed her lover, isn't it reasonable to assume that she showed him those postcards that Jossie had put up round the gallery in an attempt to locate her? Isn't it reasonable to conclude that, learning about these cards and already being involved with Gina Dickens, Frazer Chaplin began to see a way in which he could have everything: the treasure that he'd learned about, a means to get to that treasure, and Gina Dickens as well?"
Isabelle thought about this. She tried to see how it had been managed: a phone call made to the number on the postcard that would tell Gordon Jossie where to find Jemima; Jemima's decision to meet Jossie in a private location; someone in Hampshire to keep an eye on Jossie and monitor his movements and someone in London doing the same with Jemima, and both of these someones intimately involved with Jossie and with Jemima, privy to the nature of the relationship they'd had with each other; both of these someones additionally in contact; both of these someones engaged in a delicate minuet of timing ... ?
"It makes my head swim," she finally said. "It's impossible."
"It isn't," he said, "especially if Gina Dickens and Frazer knew each other from the night of the gallery opening. And it would have worked, Isabelle. Carefully planned as it was, it would have worked perfectly. The only thing they didn't take into account was Yukio Matsumoto's presence in the cemetery that day. Frazer didn't know Matsumoto was being Jemima's guardian angel. Jemima likely didn't know it herself. So neither Frazer nor Gina Dickens took into account that someone would see Jemima meet Gordon Jossie and also see Gordon Jossie leave her, very much alive."
