It left her trembling all over; and she stammered: "How horrible!... The poor fellow!... Ah, Renine, you couldn't save him this time!... And that's what upsets me more than anything, that we could and should have saved him, since we knew of the plot...."

Renine made her sniff at a bottle of salts; and when she had quite recovered her composure, he said, while observing her attentively:

"So you think that there is some connection between the murder and the plot which we were trying to frustrate?"

"Certainly," said she, astonished at the question.

"Then, as that plot was hatched by a husband against his wife or by a wife against her husband, you admit that Madame d'Ormeval ...?"

"Oh, no, impossible!" she said. "To begin with, Madame d'Ormeval did not leave her rooms ... and then I shall never believe that pretty woman capable.... No, no, of course there was something else...."

"What else?"

"I don't know.... You may have misunderstood what the brother and sister were saying to each other.... You see, the murder has been committed under quite different conditions ... at another hour and another place...."

"And therefore," concluded Renine, "the two cases are not in any way related?"

"Oh," she said, "there's no making it out! It's all so strange!"

Renine became a little satirical:

"My pupil is doing me no credit to-day," he said. "Why, here is a perfectly simple story, unfolded before your eyes. You have seen it reeled off like a scene in the cinema; and it all remains as obscure to you as though you were hearing of an affair that happened in a cave a hundred miles away!"

Hortense was confounded:

"What are you saying? Do you mean that you have understood it? What clues have you to go by?"

Renine looked at his watch:

"I have not understood everything," he said. "The murder itself, the mere brutal murder, yes. But the essential thing, that is to say, the psychology of the crime: I've no clue to that. Only, it is twelve o'clock. The brother and sister, seeing no one come to the appointment at the Trois Mathildes, will go down to the beach. Don't you think that we shall learn something then of the accomplice whom I accuse them of having and of the connection between the two cases?"

They reached the esplanade in front of the Hauville chalets, with the capstans by which the fishermen haul up their boats to the beach. A number of inquisitive persons were standing outside the door of one of the chalets. Two coastguards, posted at the door, prevented them from entering.

The mayor shouldered his way eagerly through the crowd. He was back from the post-office, where he had been telephoning to Le Havre, to the office of the procurator-general, and had been told that the public prosecutor and an examining-magistrate would come on to etretat in the course of the afternoon.

"That leaves us plenty of time for lunch," said Renine. "The tragedy will not be enacted before two or three o'clock. And I have an idea that it will be sensational."

They hurried nevertheless. Hortense, overwrought by fatigue and her desire to know what was happening, continually questioned Renine, who replied evasively, with his eyes turned to the esplanade, which they could see through the windows of the coffee-room.

"Are you watching for those two?" asked Hortense.

"Yes, the brother and sister."

"Are you sure that they will venture?..."

"Look out! Here they come!"

He went out quickly.

Where the main street opened on the sea-front, a lady and gentleman were advancing with hesitating steps, as though unfamiliar with the place. The brother was a puny little man, with a sallow complexion. He was wearing a motoring-cap. The sister too was short, but rather stout, and was wrapped in a large cloak. She struck them as a woman of a certain age, but still good-looking under the thin veil that covered her face.

They saw the groups of bystanders and drew nearer. Their gait betrayed uneasiness and hesitation.

The sister asked a question of a seaman. At the first words of his answer, which no doubt conveyed the news of d'Ormeval's death, she uttered a cry and tried to force her way through the crowd. The brother, learning in his turn what had happened, made great play with his elbows and shouted to the coast-guards:

"I'm a friend of d'Ormeval's!... Here's my card! Frederic Astaing.... My sister, Germaine Astaing, knows Madame d'Ormeval intimately!... They were expecting us.... We had an appointment!..."

They were allowed to pa.s.s. Renine, who had slipped behind them, followed them in without a word, accompanied by Hortense.

The d'Ormevals had four bedrooms and a sitting-room on the second floor.

The sister rushed into one of the rooms and threw herself on her knees beside the bed on which the corpse lay stretched. Therese d'Ormeval was in the sitting-room and was sobbing in the midst of a small company of silent persons. The brother sat down beside her, eagerly seized her hands and said, in a trembling voice:

"My poor friend!... My poor friend!..."

Renine and Hortense gazed at the pair of them: and Hortense whispered:

"And she's supposed to have killed him for that? Impossible!"

"Nevertheless," observed Renine, "they are acquaintances; and we know that Astaing and his sister were also acquainted with a third person who was their accomplice. So that...."

"It's impossible!" Hortense repeated.

And, in spite of all presumption, she felt so much attracted by Therese that, when Frederic Astaing stood up, she proceeded straightway to sit down beside her and consoled her in a gentle voice. The unhappy woman's tears distressed her profoundly.

Renine, on the other hand, applied himself from the outset to watching the brother and sister, as though this were the only thing that mattered, and did not take his eyes off Frederic Astaing, who, with an air of indifference, began to make a minute inspection of the premises, examining the sitting-room, going into all the bedrooms, mingling with the various groups of persons present and asking questions about the manner in which the murder had been committed. Twice his sister came up and spoke to him.

Then he went back to Madame d'Ormeval and again sat down beside her, full of earnest sympathy. Lastly, in the lobby, he had a long conversation with his sister, after which they parted, like people who have come to a perfect understanding. Frederic then left. These manoeuvers had lasted quite thirty or forty minutes.

It was at this moment that the motor-car containing the examining-magistrate and the public prosecutor pulled up outside the chalets. Renine, who did not expect them until later, said to Hortense:

"We must be quick. On no account leave Madame d'Ormeval."

Word was sent up to the persons whose evidence might be of any service that they were to go to the beach, where the magistrate was beginning a preliminary investigation. He would call on Madame d'Ormeval afterwards.

Accordingly, all who were present left the chalet. No one remained behind except the two guards and Germaine Astaing.

Germaine knelt down for the last time beside the dead man and, bending low, with her face in her hands, prayed for a long time. Then she rose and was opening the door on the landing, when Renine came forward:

"I should like a few words with you, madame."

She seemed surprised and replied:

"What is it, monsieur? I am listening."

"Not here."

"Where then, monsieur?"

"Next door, in the sitting-room."
