‘Disgusting,’ snarled Krantz, his pen busy.

‘If you worry about a scandal,’ said Daranyi, ‘this may be it. I keep thinking Dr. Denise Marceau means for her husband to know of her own violation of the marital bed, and I keep wondering what Dr. Claude Marceau will do when he does find out…’

At 1.02 in the afternoon, Claude Marceau had learned that his loyal spouse of ten years had become an adulteress.

At 1.08 Claude Marceau had extracted from her the name of her vile seducer.

At 1.29 Claude Marceau, linked in step with Hammarlund’s butler, Motta, was striding over the forest path behind Åskslottet to the isolated laboratory, the den of sin in the Animal Park, where he would find the infamous, lustful, treacherous Swede, Oscar Lindblom, and give him the thrashing of his life.

Claude Marceau, protector of home and hearth, was boiling mad. Nor was his rage misdirected. Denise, ever timid and fearful of violence, had tried to protect her lover by protesting his innocence and presenting herself as a femme fatale. The gesture might have been laughable had it not been so transparent and pathetic. Claude had known his wife too long and too well to be fooled. Denise was essentially provincial, bourgeois, naïve, unworldly. There had been no doubt in Claude’s mind where the blame must be put: the Swedish snake had taken vicious and caddish advantage of her distress, her weakness, and through his practised wiles had hounded her into an infidelity.

Striding beside Motta, Claude reviewed the accident that had revealed all. He had returned from Uppsala after midnight, and immediately fallen into an exhausted sleep. He had awakened too late for breakfast and too early for lunch, to find Denise lounging in the sitting-room, taking coffee and leafing through an imported Paris Match, and what had caught his eye was the flimsy pink négligé that he had not seen before and that ill became her, a married woman. She had been unaccountably vivacious, as she had been since the Hammarlund evening, and again he guessed that she had determined to show him her best side in order to woo him back.

Now, remembering: the door buzzer had sounded, and he had gone to see who it might be. The caller had proved to be a hotel servant, some relic fugitive escaped from Balzac’s La Comédie Humaine, who held before him a bottle of something or other, gift-wrapped in red.

‘I am one of the room-service help,’ the servant had announced. ‘I have the champagne Madàme requested for her husband.’

Claude had tried to think if it was his birthday. It was not. ‘I am Madàme’s husband. I will take it.’

The servant had pulled the champagne away from the stranger’s outstretched hand. Madàme had been explicit, the night before, about this. ‘No-it is not for you. I have seen her husband.’

Claude had then realized that this was a mistake. ‘I am sorry, but you have the wrong room.’

‘This is the right room,’ insisted the witless servant. ‘I spoke to Madàme here last night.’

Claude had become impatient with this tomfoolery. ‘What makes you think I am not her husband?’

‘I saw him in there last night.’ He peered past Claude just as Denise rose from the sofa, and he recognized her. ‘Madàme, here is the gift you ordered for your-’

Something had begun to penetrate Claude’s head, and he wheeled about in time to see his wife desperately waving off the room-service relic.

‘I-I-yes, it is the wrong room.’ The servant had begun to retreat when Claude was galvanized into action. He had gone after the man in the corridor and roughly collared him.

‘You saw a man in the room with my wife last night?’

The servant had been struck speechless, but a severe shaking had rattled the truth out of him, quickly, stumblingly, even to the admission that the tall young man glimpsed with Denise had been in pyjamas.

Claude had returned to the suite, slamming the door behind him, and advanced on Denise like the procureur général on a quaking defendant. The skirmish had been brief, and the defence had collapsed entirely. Foolishly, Denise had tried to take the whole burden of guilt upon herself, had even tried to transfer some of it to him. If she had not been so widowed and hurt by his affair, if she had not been so needful of love and reassurance, she would not have succumbed so easily to Oscar Lindblom’s blandishments. There, the name was out-Lindblom! The betrayer, the traducer, the Nordic Casanova! For now, to absolve herself, the truer truths poured out-Lindblom’s silken persuasion, his ardent whisperings and practised hands, his strong and urgent body, his overwhelming and irresistible passion-Lindblom!

‘There is the laboratory, Dr. Marceau,’ the butler was saying.

‘Thank you,’ snapped Claude. ‘That will be all.’

He left Motta behind, and strode vengefully to the door, gripping the knob with a strong hand that would, in seconds, bash in the face of the rapist. Since Count Axel von Fersen had played his little game with Marie Antoinette, every young Swede had fancied himself a Fersen. Au revoir, Lindblom, you will be the last of the line, Claude promised himself, and he burst into the large laboratory work-room.

At first, to his stinging disappointment, he thought the place vacant, and then, from behind the far row of beakers, he heard a voice.

‘Who is it?’

Claude rushed around the counter, and then pulled up short.

Not Lindblom, but Ragnar Hammarlund, ridiculous in a onepiece suit of overalls such as Winston Churchill had once affected, confronted him.

‘Dr. Marceau-what a delightful surprise!’

‘Where’s this chemist-this Oscar Lindblom of yours?’

‘Lindblom? Out. I sent him out on an errand. He should return shortly. May I be of service, Dr. Marceau?’

‘No, it is this Lindblom I want,’ said Claude belligerently.

Hammarlund pretended not to notice his visitor’s vexation. ‘Does he expect you?’

‘I think not.’

‘He will be honoured by your appearance, as am I. His admiration for you and your wife exceeds worship.’

Claude was too irritable to enjoy insincerity. ‘You flatter us.’

‘Not enough,’ said Hammarlund, bringing a silk handkerchief from his hip pocket and brushing his forehead. ‘Dr. Lindblom is a shy, retiring young man of modest attainments who is well acquainted with your work, and for years you have been his idol.’

This did not coincide with Claude’s picture of a lecher. ‘I had a different impression of him at your dinner-a brash, over-confident fellow-’

‘Surely you must be thinking of someone else,’ interrupted Hammarlund. ‘Why, when your wife came to visit the laboratory the other morning, Dr. Lindblom was incoherent with excitement.’

‘My wife came here?’ Claude glanced coldly about the laboratory. So this was the sordid scene of the seduction. This was where it began-and the egotism of the lecher, to celebrate the insult further, in the husband’s own hotel suite last night!

‘Yes,’ Hammarlund went on, ‘your wife was intrigued by Dr. Lindblom’s findings in the field of synthetic foods.’

‘I can imagine,’ said Claude bitterly. He looked about again, and a thought came to him: where had the seduction taken place? On the hard floor? Too incredible to conceive. ‘Is this the only room here?’

‘No, by no means. We have what we call our “think” room. Come, you can wait there for Dr. Lindblom. It will be more comfortable.’

They walked into the adjoining office, and Claude stared at the offending sofa, and it all became clear.

‘Have a seat,’ said Hammarlund. ‘May I order you something from the house?’

Although he had not yet eaten this day, Claude wanted no hospitality from a host whose employee he would momentarily reduce to minced sausage. ‘No, thank you.’ He sat stiffly on the sofa, and was somehow glad it did not squeak. He extracted an English cigarette from his silver case, and accepted the flame from Hammarlund’s lighter.
