‘I was thinking about that, actually,’ Imogen said. ‘He said they got sued by someone a couple of years ago. Who was that? I bet they have a story to tell.’

‘Good thinking. I’ll see if I can find out who it was.’

Adrian typed in the buzzwords and looked through the results. He found a small article four pages into the search engine in an old local paper about an accident that had happened on one of the Corrigan building sites. A man lost his arm owing to a faulty piece of machinery.

‘This guy lost his arm on a Corrigan building site two years ago. The timing fits. If nothing else, we know this guy used to work for the company. Maybe even at the same time as Simon Glover and Leon Quick.’

‘I just keep seeing it repeatedly. Leon Quick was a bit tense when we got there and then minutes later, he decided to take his own life,’ Imogen said, preoccupied by what had happened the day before. ‘Did we do that?’

‘I don’t think he was fine when we got there, to be honest. Did you see how jittery he was?’

‘I thought he might be on something, or you know, in withdrawal, but the preliminary path reports say he was clean.’

‘Just anxious; scared of something or someone,’ Adrian said.

‘Do you think Angela Corrigan knows why he killed himself?’

‘If she does, I don’t think she will tell us. No one seems to be telling us anything.’

‘You think Reece Corrigan is the one who gave her those injuries and left her in the river?’

‘He didn’t report her missing. He must have known where she was or thought she wasn’t coming back. Did he even care? But then, why would she go back to him?’

‘Is it a money thing? That house, that car, don’t come cheap. Is that why she stays with him? I always used to struggle to understand why a woman would choose to stay in an abusive relationship, but with the things I have seen in this job, I am just thankful for everyone who gets out. If he did think she was dead she could have been home free. She could have disappeared without a trace.’

‘I don’t think either of us are in a position to judge other people for their relationships. Maybe she’s too scared to leave. We need to speak to her alone,’ Adrian said.

He would be lying if he said he didn’t hold some resentment towards his mother for not getting out while she could, for staying with the person who made their life hell. He wouldn’t hear anyone else say that, though; she was as much a victim as he was.

‘How are you with all this?’ Imogen asked as if reading his thoughts.

‘Right now? I’m really angry. I want to get her out of there.’
