'Why did you and Frank break up?'

'I'm sorry, but I don't think that's relevant or any of your business.'

'You're right. Okay. Let's get right down to it. Why are you so convinced your husband didn't arrange Bellamy's murder? The evidence that he did was pretty compelling.'

'The word of a dying man who'd been paid to bear false witness isn't compelling to my mind.'

'He was in financial difficulties and his partner's actions were undermining his practice. I've been told he was homophobic and had come to despise Bellamy.'

'That's true, but one thing, no, two things were totally neglected in the investigation. Gregory was what's now called a control freak, Mr Hardy. He was completely unable to delegate anything. That's why he worked such insane hours and why what Peter Bellamy was doing made him so angry. He'd worked twice as hard as Bellamy to build the practice, and now it was slipping downhill despite his efforts. If Gregory had intended to kill Bellamy he would have done it himself, not entrusted it to someone else. Talk to anyone who knew him and ask if he ever allowed another person to do something for him that he considered important.'

'That's interesting but it's hardly conclusive. Killing a person isn't an easy thing to do, Mrs Heysen. It's hard enough to do in war or in self-defence, let alone in cold blood. It's got its own psychology.'

She appeared to think that over briefly, then she said, 'I'm sure you speak from experience and know what you're talking about. But you're losing sight of Gregory's profession. I know for a fact that he killed a number of people. He was a believer in euthanasia.'
