She smiled and touched his arm. ‘You’re an honest man, Tom. I will help you, but will you do one thing for me: try to take Boden alive. It is just possible he does love Lilly. And it is also feasible that he’s not a war criminal. In which case, there would be a tiny outside chance that one day he will be freed and they will be together.’

‘One other thing.’ He turned to Jerzy, who had been listening intently without saying a word. ‘I need your help, too, Jerzy.’

‘You do, boss? Sure I help you.’

‘Angie will point out the Frenchwoman – then I want you to watch her, like a spy.’

‘Don’t worry, I know who you mean. Seen her before. She don’t speak to nobody.’

‘To anybody, Jerzy – she doesn’t speak to anybody. Remember what I told you about the double negative?’

‘Sorry, Doc.’

Wilde held out a present, hastily wrapped in brown paper and string that he acquired from the Garmisch CIC post room. ‘This is for you, Jerzy, for your help. Payment in advance.’

‘For me?’

‘Open it.’

Jerzy looked puzzled. His gaze turned to Angie Gray and she nodded. ‘OK, boss.’ He carefully unwrapped the brown paper and revealed the box camera that Heck had been given by the woman at the roadside stall. ‘It’s from Mo.’

‘Really?’

‘He thought you’d like it.’

Jerzy took the camera and looked at it wide-eyed. ‘Thanks, boss.’ He turned it this way and that, cleaned the lens and viewfinder. He grinned at Wilde and at Dr Gray.

‘Sorry I’ve got no film for it, but maybe it’ll help you watch Lilly Marais.’

‘This is a good camera. I’ll get film one day, then you’ll see.’

‘You’re clear about the Frenchwoman?’

‘Sure. Mostly, she just sits alone. Always there by the gate. Except at meal times. She pretty woman, but maybe a little crazy in the head.’ The boy tapped his temple with his forefinger.

‘Does she notice you when you’re watching her?’

‘I think she don’t notice nothing.’ He caught Angie’s eye guiltily. ‘Anything.’

‘Do this and I promise I’ll find some film for your cameras,’ Wilde said.

‘Even better, boss.’ Jerzy saluted Wilde and gave him a wide grin, complete with a couple of broken teeth.

‘Good lad.’

Wilde took the photograph of the Boden family from his pocket and pointed at Julius. ‘That man in particular. That’s the man we’re looking for. But even if he doesn’t come himself and someone else comes, you must tell us. Yes?’

‘Best job I ever have.’

‘Everyone knows you go around with your camera watching people. Just carry on like that, as normal.’

‘Sure, boss.’
