Normally, Elena would have snapped back, but she knew Danny was devastated by what he'd learned about his grandfather. 'Try some other army numbers – they must be listed in the phone book. And maybe you should make the calls in the garden. We don't want anyone else knowing about this. I'll see if I can find anything online. But if we do find him, what then? Really?'

'I'll turn him in,' said Danny, picking up the phone directory. 'I want him to suffer the way he's made other people suffer.'

The garden at Foxcroft was like the quiet room, hardly ever used. There was nothing wrong with it; it was beautiful, if you liked flowers and plants that trailed in and out of trellises fixed to the high brick wall completely enclosing the garden. But as most of the residents of Foxcroft couldn't tell a rose from a stick of rhubarb, they generally stayed away.

And that suited Jane Brooker, who tended the garden almost as lovingly as she looked after the kids in her care. The garden was Jane's escape from the stresses and strains of life at Foxcroft. She needed it.

It was almost like being in the countryside. Only the constant thunder of traffic snaking its way to and from the centre of the city and the jagged broken glass cemented into the coping on top of the crumbling brick wall gave away the fact that the garden was in a busy and sometimes dangerous district.

Dave the Rave often joked that the broken glass was there to keep the Foxcroft kids in rather than keep unwanted visitors out. But it wasn't like that. Foxcroft had been burgled many times – not that there was much worth stealing.

The garden was deserted when Danny arrived with his mobile and the phone directory. He sat on a wooden bench and started to look up numbers. He tried the local recruitment office, the Army Pensions Office and even the National Army Museum. No joy.
