By the time she returned to the changing rooms, Carol was sitting on a bench, wearing nothing but a bath sheet. There were a couple of other women getting changed, so the two police officers ignored each other. But under cover of opening her locker and heading for the showers, Petra unobtrusively dropped the sauna key in Carol’s lap.

Five minutes later, they were side by side on the wooden bench, naked save for the sheen of sweat on their skin. Petra couldn’t help admiring the sleek lines of Carol’s body, the well-defined shoulders and thighs and the flat stomach. Not that she was tempted, but it would have been perverse not to notice, she told herself. ‘Did anyone follow you from the restaurant?’ she asked.

‘I don’t think so,’ Carol said. ‘I was expecting a tail, but I didn’t spot one. You came out behind me, didn’t you? Did you see anyone?’

‘No. And that surprised me too. I felt sure he’d have you under surveillance by now. He’s normally so circumspect, I can’t believe he’s leaving you alone.’

‘Maybe he’s still dazzled by my resemblance to Katerina.’

Petra wiped her damp forehead. ‘Even if Radecki is walking around in a daze, I can’t believe Darko Krasic isn’t on the ball.’

Carol shrugged. ‘Maybe he hasn’t told Krasic about me yet.’

Petra looked sceptical. ‘I don’t see it. And I don’t think Radecki is completely blinded by your looks. I spoke to your man Gandle earlier this afternoon, and he told me that one of your undercover colleagues in the UK got a call from Radecki himself last night. Apparently he claimed he was Krasic, but from the report of how good the guy’s English was, it sounds as though it was Radecki himself.’

‘That must have been when he left the box at the second interval.’ Carol leaned forward and ladled more water on the hot coals. Steam hissed and the temperature shot up, making her a little light-headed.

Petra nodded. ‘Radecki was looking for someone who could vouch for you personally. He was told you were very good at what you do, but that you’re also a loner and very cautious about who you work with. I must say, your people have calculated exactly what will appeal to Radecki.’

‘We couldn’t have done it without help from you, Petra.’

She smirked, pleased at the compliment. ‘So, how was lunch?’

Carol told her about Tadeusz’s admission that he recognized her resemblance to Katerina. ‘I almost felt sorry for him,’ she said. ‘It’s obvious that he absolutely adored her.’

‘Even if that’s true, it still doesn’t stop him dealing in the sort of racket that robs other people of the ones they love.’
