A loud and ominous booming sound welled up through the house. Caper, finding no one to whom he could announce dinner, had fallen upon an enormous gong and beaten it. Jonathan uttered a mad little giggle.

“Well,” he said, “shall we dine?”

The memory of that night’s dinner party was to be a strange one for Mandrake. It was to have the intermittent vividness and the unreality of a dream. Certain incidents he would never forget, others were lost the next day. At times his faculty of observation seemed abnormally acute and he observed, exactly, inflexions of voices, precise choice of words, details, of posture. At other times he was lost in a sensation of anxiety, an intolerable anticipation of calamity, and at these moments he was blind and deaf to his surroundings.

Only six of the party appeared for dinner. Madame Lisse, Mrs. Compline, and Dr. Hart had all excused themselves. Dr. Hart was understood to be in the “boudoir,” where he had gone after his speech in his own defence and where, apparently at Jonathan’s suggestion, he was to remain, during his waking hours, for the rest of his stay at Highfold. Mandrake wondered what Jonathan had told the servants. The party at dinner was therefore composed of the less antagonistic elements. Even the broken engagement of William and Chloris seemed a minor dissonance, quite overshadowed by the growing uneasiness of the guests. Nicholas, Mandrake decided, was now in a state of barely suppressed nerves. His injured arm was not in a sling but evidently gave him a good deal of pain and he made a clumsy business of cutting up his food, finally allowing Hersey Amblington to help him. He had come down with Hersey, and something in their manner suggested that this arrangement was not accidental. “And really,” Mandrake thought, “it would be better not to leave Nicholas alone. Nothing can happen to him if somebody is always at his side.” Mandrake was now positive that it was Hart who had made the attacks upon Nicholas and himself and he found that the others shared this view and discussed it openly. His clearest recollection of the dinner party was to be of a moment when William, who had been silent until now, leant forward, his hands gripping the edge of the table, and said: “What’s the law about attempted murder?” Jonathan glanced nervously at the servants, and Mandrake saw Hersey Amblington nudge William. “Oh, damn,” William muttered, and was silent again. As soon as they were alone, he returned to the attack. He was extraordinarily inarticulate and blundered about from one accusation to another, returning always to the ruin of his mother’s beauty. “The man who did that would do anything,” seemed to be the burden of his song. “The Oedipus complex with a vengeance,” thought Mandrake, but he was still too bemused and shaken to crystallize his attention upon William, and listened through a haze of weary lassitude. It was useless for Nicholas to say that he had never heard the name of his mother’s plastic surgeon. “Hart must have thought you knew,” William said. “He thought that Mother had told you.”

“Rot, Bill,” said Nicholas. “You’re barking up the wrong tree. It’s because of Elise Lisse. The fellow’s off his head with jealousy.”

“I’m older than you,” William roared out with startling irrelevancy. “I remember what she was like. She was beautiful. I remember the day she came back. We went to the station to meet her. She had a veil on, a thick veil. And when I kissed her she didn’t lift it up and I felt her face through the veil and it was stiff.”

“Don’t, Bill,” Hersey said.

“You heard what she said — what Mother herself said. She said up there in your room: ‘Nicky’s found out. He’s afraid Nicky will expose him.’ God, I’ll expose him. He’s gone to earth, has he? I’m damn well going to lug him out and—”

“William!” Jonathan’s voice exploded sharply, and Mandrake roused himself to listen. “William, you will be good enough to pull yourself together. Whether you choose to do your mother an appalling wrong by reviving for public discussion a tragedy that is twenty years old, is your affair. I do not attempt to advise you. But this is my house and I am very much your senior. I must ask you to attend to me.”

He paused, but William said nothing, and, after a moment, Jonathan cleared his throat and touched his spectacles. Mandrake thought dimly: “Good Heavens, he’s going to make another of his speeches.”

“Until this evening,” Jonathan said, “I refused to believe that among my guests there could be one — ah — individual, who had planned, who still plans a murderous assault upon a fellow guest. I argued that the catastrophe at the swimming-pool was the result of a mischievous, rather than a malicious attack. I even imagined that it was possible poor Aubrey had been mistaken for myself.” Here Jonathan blinked behind his spectacles and the trace of a smirk appeared on his lips. He smoothed it away with his plump hand and went on very gravely. “This second attempt upon Nicholas has convinced me. If that idol, which I may say I have always rather disliked, had fallen, as without a shadow of doubt it was intended to fall, upon his head, it would have killed him. There is no doubt at all, my dear Nick, it would have killed you.”

“Thank you, Jonathan,” said Nicholas with a kind of sneer, “I think I realize that.”

“Well, now, you know,” Jonathan continued, “this sort of thing is pretty bad. It’s preposterous. It’s like some damn pinchbeck story-book.”

“Jo,” Hersey Amblington interjected suddenly, “you really can’t keep us all waiting while you grizzle about the aesthetic poverty of your own show. We’re all agreed it’s a rotten show, but at least it has the makings of a tragedy. What are you getting at? Do you think Dr. Hart’s out for Nick’s blood?”

“I am forced to come to that conclusion,” said Jonathan primly. “Who else are we to suspect? Not one of ourselves, surely. I am not breaking confidence, I hope, Nick, when I say that Hart has threatened you, and threatened you repeatedly.”

“We’ve heard all about that,” Hersey grunted.

“Ah — yes. So I supposed. Well, now, I am a devotee of crime fiction. I have even dabbled in quite solemn works on the detection of crime. I don’t pretend to the smallest degree of proficiency, but I have ventured to carry out a little investigation. Nicholas tells me that ten minutes before he so nearly became the victim of that atrocious booby-trap, he left his room and — ah — visited that of Madame Lisse.”

“Oh Lord!” Hersey muttered, and Mandrake thought he heard Chloris utter a small contemptuous sound.

“This was, of course, a reckless and foolish proceeding,” said Jonathan. “However, it has this merit — it frees Madame Lisse from any imputation of guilt. Because Nick, when he left his room, opened and shut the door with impunity, and was talking to Madame Lisse until he returned to sustain the injury to his arm. Nick tells me he heard the clock on the landing strike the half-hour as he walked down the passage to Madame’s room. I had glanced at the drawing-room clock not more than a minute before the crash and it was then twenty to eight. The two clocks are exactly synchronized. As the trap could not have been set until after Nick left his room, that gives us ten minutes for our field of enquiry. Now, at the time of the accident, Aubrey and I were both in the drawing-room. I found him there when I came down and actually heard him go downstairs some little time before that. I am therefore able to provide Aubrey with an alibi and I hope he will vouch for me. Now, can any of you do as much for each other?”

“I can for Sandra,” said Hersey, “and I imagine she can for me. I was in her room talking to her when Nick yelled, and I’m sure I’d been there longer than ten minutes. I remember quite well that when I passed Nick’s door it was half open and the light on. I saw him beyond the door in his room and called out something.”
