“Your cousin gets wind of something fishy. She doesn’t know what to do, so she asks Forster, who has assisted the family in the past. He looks hard, and eventually produces proof that your money is more than a little dodgy. Nails it down just after you’d stolen the Vélasquez.
“She confronts you with it. And dies. I don’t think she killed herself, nor do I think Forster killed her. You murder her because she has found out about you. You slip her the extra pills and leave her.
“Forster’s mistake is to try to blackmail you, rather than going straight to the police. You decide to murder him as well at the appropriate moment.
“But before you do that, you have to make sure that you can get your hands on whatever evidence he might have accumulated. So, instead of that nonsense about Fancelli telling the police against your wishes, you actually tell her to go to the police, to stir Forster up.
“It works very nicely. The moment I talk to him, he makes an appointment to see me and goes out to get his evidence. Winterton tells you the bait has been taken, you go down, kill him and take it all away.
“And George Barton’s confession? You heard it, after all.”
“George Barton didn’t say anything about killing him. The whole conversation could just as easily have been about how he’d seen you coming out of Forster’s house that evening. Because he likes you, and didn’t like Forster, he was telling you he wouldn’t say anything.”
“And hasn’t.”
“No. And probably won’t. This is an extraordinary tight-lipped place. Anyway, Forster’s dead, you’ve destroyed the evidence, and you think you’re in the clear. Until you realize that we are looking for more evidence. So you do the next best thing: you bum his papers, in the hope we’ll stick with Forster, and as a fall-back you keep on dropping hints here and there about your crazy cousin. Not knowing how she kept the place going with so little money. Going on fugues. Interested in art. Dr. Johnson said she stole things, but he also said that you told him that.
“And all along, right in front of our noses, there is the reason: the Vélasquez stolen from Milan a couple of years back; waiting, I assume, to be collected.”
Mary Verney gave a heavy sigh, and looked at him sadly. “I am sorry, Jonathan,” she said eventually after debating how to approach the issue and then deciding that there was little point in being anything but straightforward. “You must be feeling quite dreadfully abused.”
This was the trouble. Not only was she a thief and a murderer, he had just proven it. Morally, at least. But she was still charming and he still liked her. Damn the woman.
“That is putting it mildly.”
“I suppose you don’t think too highly of me.”
“Two murders, God knows how many thefts, framing Forster and your cousin, manipulating Jessica Forster, lying through your teeth to me and Flavia and the police. I’ve come across people who are better socially adapted. I mean, why? You’re really nice. You have intelligence, and presence…”
“And I could have been an honest woman. Married to someone I didn’t care for, doing a job that bored me, growing old and frightened about not having enough money to retire on, living in a poky little flat somewhere, which was all I had to look forward to after this family of mine had done their worst. Yes. I could have done that. But why the hell should I have done?”
“And instead you chose to steal other people’s property.”
She sniffed. “If you like. So I’m a thief. But I never destroyed anything or took from people who couldn’t afford it. Most of them didn’t even know the value of the paintings I took. They only made a fuss later. I have stolen thirty-one paintings. The nineteen we told you about will soon be back in the hands of their original owners. Of the remainder, one by one they will drift back into the public gaze. In essence, they are borrowed, as all paintings are, really. You cannot own a painting; you are merely its custodian for greater or shorter periods. They all still exist, after all, and many are better looked after than they were before.”
“But property, and legitimate ownership…”
“Oh, Jonathan, really. Stop puffing up like that. Even though I only met you a few days ago, I know you better.”
“Do you indeed?”
“Well enough to know that such statements don’t mean much to you. The Calleone Vélasquez. Do you know where the money came to buy that? Centuries of screwing the peasants, and massacring the natives in South America. The Dunkeld Pollaiuolo, owned by an English aristocrat who’d squeezed Ireland dry for two hundred years. What I do is wrong, I suppose. But at least I don’t pretend I’m a public benefactor.”
“If that’s all there was to it, I would be half inclined to agree with you. But there’s more than that, isn’t there? You killed two people. Don’t you feel guilty about that? Just a little.”
