‘Since we saw you last, Dr da Silva,’ Brock began, ‘we’ve had a chance to check some of the things you told us.’ He stopped and stared at the man across the table.
Da Silva tried to meet his eyes, but only succeeded in looking shifty. He was a changed man, Kathy thought, the arrogance gone along with the colour from his face. His clothes looked crumpled and soiled, as if he’d slept in them on someone’s sofa, and she wondered if his wife had thrown him out. He took a pair of glasses out of his pocket and put them on with an unsteady hand, as if for protection.
‘We’ve been trying to confirm your account of your movements on Tuesday the third of April, the day that Marion Summers was poisoned, but without success. None of your neighbours saw you that day, you made no calls through your house phone nor received any. There’s no evidence of you being at home that day at all.’
Da Silva’s solicitor began to object, but Brock simply nodded his head patiently and then went on, questioning the tutor again about the details of that day, what he’d had for lunch, what letters he might have written (none), and emails he might have sent from his home computer.
‘No, nothing like that. I told you, I was completely engrossed in the paper I was writing for a conference presentation that was overdue.’ His voice was different, like a nervous public speaker whose throat is stretched tight with tension.
They would require his computer, Brock said, and would carry out a search of his home, although from his tone he didn’t expect to find much. He moved on to the days following Marion’s death, and da Silva’s visit to her house.
‘I spoke to Keith Rafferty,’ Kathy said. ‘He denied that he’d supplied you with a key.’
Da Silva made a noise intended as a scoff but that came out as a choke. He took a sip from the plastic cup in front of him and said, ‘That’s no surprise.’
They turned to his relationship with Dr Ringland and access to his laboratory, laboriously working through every detail until eventually the solicitor said, ‘I think that’s really enough. As you can see, Dr da Silva is suffering greatly from the strain of these terrible events, of which he is entirely innocent. Unless you have something specific to ask him, I’m going to advise him to say no more.’
‘It’s true!’ da Silva blurted out, loud enough to make his solicitor glance at him in alarm. ‘You… you’re trying to make me out to be some kind of predator, preying on girls like Marion and Tina. But I’m innocent! I was proud of Marion, proud of her as a father might be proud of his daughter, proud of her development, of her intelligence and insight. Proud of her independence, too, of her refusal to accept my opinion on trust, difficult as that sometimes was.’
There were tears in his eyes now, and the three other people in the room, despite their long experience of such situations, drew back a little in embarrassment.
‘When she hid her Cornell paper from me, and I began to suspect the way in which it was intended to undermine me, I felt bitterly betrayed. Her disloyalty was like a knife in my heart. But I never, for one moment, thought of hurting her. That is obscene.’
Silence filled the room, then Brock said mildly, ‘Where were you on the afternoon and evening of Wednesday the eleventh of this month, Dr da Silva?’
‘What?’
‘A week ago, between the hours of three and eight. Please think carefully before you answer.’
Da Silva frowned, then reached into his jacket pocket and brought out a small diary. ‘Umm… lunch with Dr Ringland, a two o’clock lecture, then…’ He looked up. ‘I believe I went up to the British Library.’
‘What was the lecture?’
‘Victorian literature.’
‘To?’
‘Third-year arts students mainly. Why?’
‘Tina Flowers was in that class, wasn’t she?’
‘Um… it’s possible, I suppose.’
‘And then she went to the British Library, where, shortly after four o’clock, she requested two books. Do you know what they were?’
‘How could I?’
‘Because the following morning you returned to the library as soon as it opened, and requested those same two books, books so obscure that almost nobody else has ever requested them.’
‘Um… I believe I do remember. Marion had told me about them.’
Brock shook his head impatiently. ‘You followed Tina after the lecture up to the British Library, and watched her order the two books, one of which was the source of Marion’s revelations in her Cornell paper. You had been unable to find that book because it was stored in one of the special collections, the papers of the Havelock family, a name slightly different from the one you’d been searching for-Haverlock.
Da Silva sat rigid in his chair.
‘Where is that book now, Dr da Silva? You collected it the following day, but never returned it. Where is it?’
He said nothing, jaw locked.
‘Did you hide it somewhere in the library?’ Kathy pressed.
For a moment it seemed he would keep silent, but then he gave a kind of shudder and whispered, ‘She just read and read and read, completely engrossed, but she seemed to make no notes, nor photocopies, before the library was closing and she had to hand it back. So the next morning I was there before her and took out the book. It was a scurrilous store of gossip, that’s all; a travesty, full of innuendo and rumour. Marion should never have considered it seriously. It was unconscionable that it should cause so much distress. I knew exactly what Rossetti would want me to do with the damn thing, and I did it.’
‘You did what?’ Kathy asked softly.
‘I destroyed it,’ he said defiantly. ‘I tore it into shreds and flushed it down the loo. There, I destroyed a library book. You can arrest me for that.’
‘But Tina had read it,’ Brock said, ‘just as Marion had before her, so you had to destroy her, too, didn’t you?’
•
Guiltily, Kathy now also felt like a disloyal daughter. Brock was energised by the arrest, firing instructions to the team-her team-to fill the gaps in their case against da Silva. She worked with him, of course, following up his ideas, adding her own, yet all the time she held back a little, feeling they’d got something wrong. It worried her that he hadn’t been immersed in the case as she had been, but was that just pique at having him take over now? But if there was some flaw, it was up to her, who should have developed a deeper understanding of the dynamics, to put her finger on it.
She puzzled over this later that night, when she finally got home and sat on her sofa with a burger on her lap, staring up at her wall. The diagram, she had to admit, looked pretty convincing with da Silva in the centre, the perfect counterpart to Marion’s pattern on the left with Rossetti in that central place, ringed by his women, and Kathy could almost sense that Marion would have approved. So what was wrong?
She went to bed without an answer, overtired and uneasy. She soon fell into a deep sleep, only to wake again after a couple of hours. Her brain immediately began whirring with images of imagined scenes-Marion collapsing in the library, Pip in the pub with Rafferty and Crouch, Ogilvie tumbling down the library stairs, Douglas Warrender meeting Marion in Bastia, then returning across flower-covered hills to suffer a pool-side barbecue with his family and friends…
No, that was wrong. She opened her eyes in the pitch-dark room, remembering Warrender’s remark in St James’s Park: We were a perfect couple, making friends with other holidaying couples at the local restaurants, entertaining neighbours around the pool…
A perfect couple, not a perfect family. Was Emily with them? Kathy realised they’d never checked.
And suddenly it came to her that what had been wrong from the start was the way in which Marion and Tina had died. It was entirely plausible that da Silva, or Douglas Warrender, or even Keith Rafferty, might have desperately wanted Marion dead. But how would they do it? A hit and run, perhaps. An attack in a dark street. A strangling in a car, the body dumped. Something desperate, brutal and anonymous. But not arsenic poisoning.
