‘I’d be lying if I said that it was.’

Rebus tried to find the requisite amount of iron in her words. Tried but failed.

‘Yes,’ he said, ‘I believe your husband was, well, a bit difficult at times.’

‘I won’t deny that either. He could be a real bugger when he wanted to.’ She smiled, as if in memory of the fact. ‘But I’ll miss him. Aye, I’ll miss him.’

‘I’m sure you will, Mrs Gallagher.’

He looked at her, and her eyes fixed on to his, challenging him. He cleared his throat again. ‘There’s something I’m not absolutely sure about, concerning the accident. I wonder if maybe you can help me?’

‘I can try.’

Rebus smiled his appreciation. ‘It’s just this,’ he said. ‘Eleven o’clock was a bit early for your husband to be coming downstairs. What’s more, he seemed to be trying to come down without his walking-frame, which is still beside the bed.’ Rebus’s voice was becoming firmer, his conviction growing. ‘What’s more, he seems to have fallen with a fair amount of force.’

She interrupted him with a snap. ‘How do you mean?’

‘I mean he fell straight down the stairs. He didn’t just slip and fall, or stumble and roll down them. He went flying off the top step and didn’t hit anything till he hit the ground.’ Her eyes were filling again. Hating himself, Rebus pressed on. ‘He didn’t fall, Mrs Gallagher. He was helped to the top of the stairs, and then he was helped down them with a push in the back, a pretty vigorous push at that.’ His voice grew less severe, less judgmental. ‘I’m not saying you meant to kill him. Maybe you just wanted him hospitalised, so you could have a rest from looking after him. Was that it?’

She was blowing her nose, her small shoulders squeezed inwards towards a brittle neck. The shoulders twitched with sobs. ‘I don’t know what you’re talking about. You think I… How could you? Why would you say anything like that? No, I don’t believe you. Get out of my house.’ But there was no power to any of her words, no real enthusiasm for the fight. Rebus reached into his pocket and brought out the newspaper.
