‘It’s a prescription sleeping pill. Iqbal told me he took pills to help him sleep when he’d been on a night shift. But I don’t think he opened the door to anyone that night.’

‘So the killer had a key?’ Judith asked. ‘Is that what you’re saying?’

‘That’s the only thing that makes sense, but I know how security conscious Iqbal was. I mean, he wouldn’t even give me a key to his side gate so I could pick up Emma. Every day he’d open the gate for me, or leave it open when he knew I was coming. I even asked him about it one day. I said it would be easier if he just gave me a key, but he wouldn’t. He said he’d rather let me in.’

‘So if he wouldn’t give a key to you, who would he give a key to?’ Judith asked.

‘That’s the thing, we all went to his funeral. The only people there who weren’t us had been told to attend by Imam Latif. There’s no one he’d give his key to.’

‘You’d give it to your neighbour,’ Becks said, almost to herself.

‘What’s that?’ Judith asked.

‘We don’t give the front door key of the vicarage to anyone. But we have given a copy to our neighbour.’

‘Of course!’ Judith said, suddenly excited. ‘You give it to your neighbour, that’s exactly what Iqbal did.’

‘But how does that help us?’

‘Because Iqbal’s neighbour was Ezra. And they were good friends, so I’m sure Iqbal trusted him with a key.’

‘But Ezra’s dead,’ Suzie said. ‘What are you saying?’

‘Think about it. There’s Iqbal’s key in Ezra’s house. In a cupboard. Or a drawer. Ezra dies, and who inherits his entire estate, including the contents of his house? One Andy Bishop. All Andy has to do is go through Ezra’s house, as I’m sure he did after the old man died, and he’d have found the spare key to Iqbal Kassam’s house.’

‘Hang on, I don’t understand,’ Becks said. ‘Are you saying Andy Bishop killed Iqbal after all?’

‘All I know is, Andy had a motive to kill him, and now we know that he might have had the opportunity as well. In fact, he’s possibly the only person who’d have been able to let himself into Iqbal’s house without needing to break in.’

‘But he was in Malta at the time,’ Suzie said.

‘Then what if they’re working for each other?’ Becks said.

The women looked at each other.

‘Keep talking,’ Suzie said.

‘Well, Andy Bishop kills Stefan Dunwoody for Elliot Howard. And then Elliot Howard kills Iqbal Kassam for Andy Bishop.’
