Gemma was waiting when Kincaid and Cullen came out of Dominic Scott's house. 'Kate's not finished, then?' she asked.
'Not quite,' Kincaid told her. He looked tired, she thought, as if the last half hour spent with Dominic Scott's body had drained him. 'His mother said he had a problem with prescription drugs. Well, it was a bit more than that. It looks like we guessed right. He was a raging junkie, and had been for a good while. And he was self- harming, at the least.'
'Cutting?' When Kincaid nodded, she said, 'Do you think his mother knew?'
He sighed. 'I don't know. I can't gauge her. And parents have an enormous capacity for self-deception.'
'Why does it matter whether she knew or not?' asked Cullen. 'It puts him squarely in the frame, and so does his suicide. He needed money to pay off his suppliers. He nicked the diamond brooch, then got his girlfriend to put it up for sale through Pevensey. Then, when you came round saying Erika had claimed it, he got the wind up. Didn't want his name connected, so killed the girlfriend, then Pevensey, then topped himself because he felt guilty.'
'First off,' Gemma said sharply, 'she wasn't the
'Maybe he just didn't want his mum to find out,' Cullen shot back.
Kincaid shook his head. 'No. There's something we're missing. We-'
'David Rosenthal's murder,' said Gemma, and they both stared at her. 'I've been thinking. Erika's husband was killed a stone's throw from here. In Cheyne Gardens.' She pointed east, towards the Albert Bridge. 'His murder was never solved.'
'A long stone, that,' Cullen said skeptically, but Gemma cut him off.
'No, listen. The detective who was investigating the case died-accidental drowning, possibly suicide, according to the report-and David Rosenthal's murder was never officially closed.'
'But that was more than fifty years ago,' put in Kincaid. 'How can that have any bearing on this?'
'I don't-' Gemma's phone rang. She gave Kincaid an apologetic glance as she pulled it from her bag. When she saw that it was Melody, she answered. 'Melody, can I ring you back? There's been-'
'Boss,' Melody interrupted, 'you know that issue of the
Gemma listened, and when Melody had finished, said, 'Can you send it to me? Right. Thanks. I'll ring you back.'
She disconnected and looked at Kincaid and Cullen. 'I think I just might be able to tell you.'
CHAPTER 20
The photo on Gemma's phone was black and white, obviously reproduced from old newsprint, but it was still possible to see that the man in the picture bore a strong resemblance to Ellen Miller-Scott.
'It's Joss Miller,' Gemma told Kincaid and Cullen as she passed the phone across. 'Accepting some sort of award for his philanthropic contributions to an art museum.'
'Ellen Miller-Scott's father?' said Cullen. 'But I don't see what an old photo-'
'Wait.' Gemma grabbed her phone back and tapped the screen. 'It's not just an old photo. This picture ran in the

'David Rosenthal never came to Chelsea. According to the detective who investigated his murder, Rosenthal had a very fixed routine. He taught at a Jewish school in North Hampstead. He lived in Notting Hill. And any free time he had, he spent in the Reading Room at the British Museum, working on a book about which he was very
