From outside came the noise of a diesel engine. Gabrielle put her head around the door. ‘The ambulance is here. I’ll go and find you some clothes we can take with us.’

Hoffmann tried to rise. Leclerc came over to help him, but Hoffmann waved him away. The Swiss, he thought sourly: they pretend to welcome foreigners but really they resent us. Why should I care if he lives in France? He had to rock himself forward a couple of times before he had gained sufficient momentum to escape the sofa, but on his third attempt he managed it and stood swaying on the Aubusson carpet. The clamour in his head was making him feel nauseous again.

Leclerc said, ‘I do hope this unpleasant incident hasn’t put you off our beautiful country.’

Hoffmann wondered if he was joking, but the inspector’s face was perfectly straight.

‘Not at all.’

Together they went out into the hall, Hoffmann taking exaggerated care with each step, like a drunk who wishes to be thought sober. The house had become crowded with people from the emergency services. More gendarmes had arrived, along with two ambulance personnel, a man and a woman, wheeling a bed. Confronted by their heavy government-issue clothing, Hoffmann once again felt naked and vulnerable; an invalid. He was relieved to see Gabrielle coming down the stairs with his raincoat. Leclerc took it from her and draped it around Hoffmann’s shoulders.

By the front door, Hoffmann noticed a fire extinguisher, wrapped in a plastic bag. The mere sight of it gave him a twinge of pain. He said, ‘Are you going to put out an artist’s impression of this man?’

‘We might.’

‘Then now I think of it, there’s something you should see.’ It had come to him suddenly, with the force of a revelation. Ignoring the protests of the ambulance people that he should lie down, he turned and walked back along the hall to his study. The Bloomberg terminal on his desk was still switched on. Out of the corner of his eye he registered a red glow. Almost every price was down. The Far Eastern markets must be haemorrhaging. He switched on the light and searched along the shelf until he found The Expression of the Emotions in Man and Animals. His hands were trembling with excitement. He flicked through the pages.
