It fleetingly distracted Lucy from DI Blake herself. But not for long. While most of her team wore casual gear – jeans, sweat-tops, trainers and the like – the DI was almost formally attired in a neat grey skirt-suit, pearl blouse and heels. She tapped her pen on the desk as she checked through the last few pages that Beardmore had supplied her with.

‘Do you trust your informant, DC Clayburn?’ she suddenly asked.

‘I suppose so, ma’am,’ Lucy replied.

‘He’s no track record for giving you duff intel?’ Blake wondered.

‘Not so far. This one’s thin on detail though, I must admit.’

‘Well …’ Blake had another long think, ‘technically, these are robberies and that puts them in our ballpark.’ She glanced at Beardmore. ‘I think we can run with this for a couple of weeks, Stan. But we haven’t got the resources to cover every cashpoint in the borough.’

‘I anticipated that, ma’am,’ Lucy said, unfolding another sheet of paper, this one a street-map of central Crowley. ‘That’s why I suggest we focus on these particular cashpoints here.’ She spread it on the desk, indicating ten separate locations which she had marked with biro crosses.

DI Blake stood up to assess it properly.

‘Ten of them,’ she said. ‘Only ten?’

‘I guessed we’d have to concentrate our resources to a degree,’ Lucy explained. ‘So, these, to me, will be his most likely targets. I’ve chosen them on the basis that he’ll do his research. He’ll have to – he’s a stranger in town, or at least he’s not a resident, so he’s not going to be overly familiar with the layout.’

She glanced at Beardmore, who remained studiedly indifferent. She could imagine that he wasn’t best pleased at the amount of attention she’d clearly been paying to this particular case, when she was supposed to be concentrating on something else. On the other hand, he ought to be a little proud that she was now demonstrating to the head of a specialist unit just how thorough and professional his own divisional officers could be.

‘Go on,’ Blake said. ‘I’m listening.’

‘Well … all of these work in his favour, ma’am,’ Lucy said. ‘They’re all in areas extensively covered by CCTV, but he’s got a hood. And the fact it’s a mucky October means he can walk the streets with his hood drawn up and not attract any attention. So, he’s got that base covered. In addition, they’re all out in the open.’ She moved her index finger from one point to the next. ‘A high street, a junction with traffic lights, the edge of the market square …’

‘And that’s an advantage to him?’ one of Blake’s underlings asked.
