‘By the way,’ he said as he cleared their plates from the table, ‘there’s been news of our old friend from Porquerolles.’

‘Milraud?’ Liz asked in astonishment.

‘Not Antoine,’ said Martin, as he came back from the kitchen. He filled her glass with the last of the bottle of Beaune they had shared. ‘His wife, Annette. She was spotted in Versailles, of all places, but by the time we heard about it, she’d disappeared.’

‘I’m amazed she risked showing her face in France.’

‘She has always loved the high life. Hiding out with her husband in one of the new Soviet republics would have palled for her very quickly. I am just hoping that Antoine has come with her. Then we’ll get him,’ Martin said with a hint of steel in his voice.

They moved into the sitting room; Liz stood by the window, holding her glass, looking out at the little square across the street. The hour’s time difference with England meant dusk was starting to fall, and a small circle of old men were finishing a last game of boules. Small powdery explosions of dust flew up each time a player carefully tossed a heavy silver-coloured ball.

‘A little Armagnac?’ asked Martin.

‘No, thanks. I’ll just finish my wine.’

‘So you’re seeing Isabelle on Monday?’

‘Yes. We’re going to compare notes – as she said, there wasn’t much time at the conference to go into detail.’

He nodded, but didn’t ask any more questions. Early on in the relationship they’d established an understanding about discussing their work, which meant never enquiring in any detail about what the other was doing.

Now he got up and stood beside Liz at the window. The players were finished for the evening and were packing their boules away in small leather pouches. Martin put his arm round her. ‘Liz,’ he said tenderly, ‘I’ve got a suggestion to make… and I don’t want your answer right away.’
