‘Well, I want both of you to see the counsellor and talk this through.’

‘We’re fine,’ Imogen said, huffing.

‘Then it shouldn’t be a very long session, should it?’ DCI Kapoor replied, conversation over.

‘Yes, Ma’am,’ Adrian said.

‘What did he say then, before he died? What the hell was he hiding?’ DCI Kapoor said.

‘He gave us an envelope with a letter for Fiona Merton inside. A goodbye letter from Simon, saying he was leaving and not to worry about him. We’ve handed it to Gary to match handwriting samples. Quick also gave us a Jiffy bag that had two brand-new passports in there. They were vacuum-packed, but we got one of the forensic techs to open it. They belong to Simon and the woman from the hospital, Jane Doe, but with a false name for him, so we assume for her also.

‘There were also train tickets into London, then Eurostar tickets to Paris, France, and then a flight to Montreal, Canada. Judging by what happened to them, I would say they were running away from someone. When we asked Leon Quick about their time at Corrigan Construction and why they left, he got more and more anxious. That seemed to be the trigger for … what he did. We were in there less than ten minutes,’ Imogen said.

‘Well, brace yourselves. The family liaison officer has been speaking to the Quicks. They are obviously very distressed, said he was fine before you got there but obviously dead when you left. The parents were understandably upset by the whole thing and so the FLO is trying to make sure they are OK and also advise them against lodging a complaint, which they had mentioned. She’s very good, so I am sure it will be fine.

‘Walsh is already looking into Leon Quick to see if he has any history of mental health issues or suicidal tendencies,’ DCI Kapoor said.

‘I just don’t understand what happened. Something we asked him provoked that extreme reaction in him. He looked terrified of something. Then he picked up that knife and stabbed himself. How do you even do that? How do you push a knife into yourself like that?’ Adrian said.

‘I’ve never seen anything like it,’ Imogen said.

‘I just don’t understand what could have been so bad that he would rather kill himself than talk about it. And kill himself like that, too. To just make that decision in that split second like that. I feel sick just thinking about it,’ Adrian said.

‘Do you think he was involved in Simon Glover’s death? Maybe he felt guilty,’ DCI Kapoor said.

‘It didn’t seem so. It wasn’t guilt, it was fear,’ Imogen said.
