‘But even if his office window is open, how can we get in?’ Judith asked.

‘We climb in.’

Judith hooted with laughter.

‘There’s no way we could climb in through a window!’

‘All we have to do is make sure we can get up to it. You said it was a ground-floor window.’

‘I know, but it’s still quite a way off the ground.’

‘Then we’ll have to get a ladder.’

‘I think people might notice if they saw two older women walking around Marlow with a ladder.’

‘I suppose. So what can we do?’

This seemed to stump Judith. But not for long.

‘We’ve got one thing going for us, haven’t we?’

‘What’s that?’

‘We’re invisible.’

‘How do you mean?’

‘It’s like I said. We’re “older” women, aren’t we? No one notices women over the age of about forty.’

‘You can say that again,’ Suzie said, chuckling darkly. ‘My days of turning heads are long gone.’

‘More fool the rest of the world, as far as I’m concerned,’ Judith said primly. ‘But society’s decided that I’m just a little old lady. Invisible, as I say. We should play to that.’

‘In what way?’

‘Well, we should try and look even more old and decrepit than we are.’

‘You mean, go around in a wheelchair?’

‘You know what,’ Judith said, ‘I think a wheelchair is exactly what we’re looking for. One of those old ones with strong brakes. Although where could we possibly get one from?’

‘I reckon I know,’ Suzie said.

‘You do?’ Becks said.

‘There’s one for sale in the Marlow Hospice shop.’

‘You’re right, there is!’ Judith agreed.

This surprised Suzie.

‘You go into charity shops?’

‘Of course I go in charity shops. Where else am I going to get my jigsaws from?’

‘Well, you learn something new every day. But if we can get ourselves an old wheelchair, I think we can get into Andy’s office. And I reckon we’ll be able to get everything else we need from the charity shops on the High Street. But it’s no bloody good.’

‘Why not?’ Judith asked.

‘Because we’ll need you to sit in the wheelchair, as you’re the oldest here. And I’ll need to push it, as it’ll be me who goes in through the window. But we’ll also need someone who can enter the building from the front and create a diversion.’

‘I’ll do it,’ Becks said.

‘What’s that?’

‘Does this other person break the law?’

Suzie wrinkled her nose.

‘I don’t think so.’

‘And does she have anything to do with the break-in?’

‘God no. I don’t think anyone at the solicitors will even realise the third person had anything to do with it.’

‘Really?’

‘I reckon so.’
