It must have been Irene. Damn. If he’d told her once, he’d told her a hundred times never to contact him at the weekend. Presumably the temptation to send him birthday greetings had proved too strong. ‘We’ll celebrate my twentieth on Monday,’ he’d said when they parted. She’d frowned. ‘Your twentieth?’ ‘ Certo, amore. Whenever I’m with you I feel thirty years younger.’ Which was true. Dark, short and skinny, Irene was no one’s idea of a pin-up, but she had a dirty, driven quality that he found extremely sexy. Just the same, that wouldn’t stop him doubling the usual ration of precoital welts to her buttocks as punishment for this indiscretion. Gli ordini vanno rispettati. Rules were rules. Andreina’s astounding inability to learn Italian had got him off the hook on several occasions, but if she had happened to see this particular message, he’d have had the hell of a time trying to talk his way out of it.

But the message wasn’t from Irene. Water crawled coldly down the man’s back as he read it. 348 393 9028: MEDUSA. After the heated pool, the air was distinctly cool, even down here in the sheltered terraces above Lake Lugano. He keyed in the number, then turned to face the hillside behind the villa.

‘We need to talk. Drive to Capolago and take the little train up Monte Generoso. Get off at Bellavista. Tell no one. Come immediately and alone.’

He was suddenly furious.

‘Don’t give me orders, Alberto! I’m not in the army any more.’

‘You still are when it comes to this. We all are, all three of us.’

‘What the hell are you talking about?’

‘They’ve found Leonardo.’

The only upside to the whole business was that Andreina was predictably furious. ‘But what about lunch? I’ve got a table for fifteen booked at Da Candida! Everyone’s coming! You can’t just change your plans at the last moment like this!’
