"Oh, I played a round of golf with Jacques d'Ormeval, who rather fancies himself as an athlete, and I played at dolls with their two charming little girls!"

The d'Ormevals came up and exchanged a few words with them. Madame d'Ormeval said that her two daughters had gone back to Paris that morning with their governess. Her husband, a great tall fellow with a yellow beard, carrying his blazer over his arm and puffing out his chest under a cellular shirt, complained of the heat:

"Have you the key of the cabin, Therese?" he asked his wife, when they had left Renine and Hortense and stopped at the top of the stairs, a few yards away.

"Here it is," said the wife. "Are you going to read your papers?"

"Yes. Unless we go for a stroll?..."

"I had rather wait till the afternoon: do you mind? I have a lot of letters to write this morning."

"Very well. We'll go on the cliff."

Hortense and Renine exchanged a glance of surprise. Was this suggestion accidental? Or had they before them, contrary to their expectations, the very couple of whom they were in search?

Hortense tried to laugh:

"My heart is thumping," she said. "Nevertheless, I absolutely refuse to believe in anything so improbable. 'My husband and I have never had the slightest quarrel,' she said to me. No, it's quite clear that those two get on admirably."

"We shall see presently, at the Trois Mathildes, if one of them comes to meet the brother and sister."

M. d'Ormeval had gone down the stairs, while his wife stood leaning on the bal.u.s.trade of the terrace. She had a beautiful, slender, supple figure. Her clear-cut profile was emphasized by a rather too prominent chin when at rest; and, when it was not smiling, the face gave an expression of sadness and suffering.

"Have you lost something, Jacques?" she called out to her husband, who was stooping over the shingle.

"Yes, the key," he said. "It slipped out of my hand."

She went down to him and began to look also. For two or three minutes, as they sheered off to the right and remained close to the bottom of the under-cliff, they were invisible to Hortense and Renine. Their voices were covered by the noise of a dispute which had arisen among the bridge-players.

They reappeared almost simultaneously. Madame d'Ormeval slowly climbed a few steps of the stairs and then stopped and turned her face towards the sea. Her husband had thrown his blazer over his shoulders and was making for the isolated cabin. As he pa.s.sed the bridge-players, they asked him for a decision, pointing to their cards spread out upon the table. But, with a wave of the hand, he refused to give an opinion and walked on, covered the thirty yards which divided them from the cabin, opened the door and went in.

Therese d'Ormeval came back to the terrace and remained for ten minutes sitting on a bench. Then she came out through the casino. Hortense, on leaning forward, saw her entering one of the chalets annexed to the Hotel Hauville and, a moment later, caught sight of her again on the balcony.

"Eleven o'clock," said Renine. "Whoever it is, he or she, or one of the card-players, or one of their wives, it won't be long before some one goes to the appointed place."

Nevertheless, twenty minutes pa.s.sed and twenty-five; and no one stirred.

"Perhaps Madame d'Ormeval has gone." Hortense suggested, anxiously. "She is no longer on her balcony."

"If she is at the Trois Mathildes," said Renine, "we will go and catch her there."

He was rising to his feet, when a fresh discussion broke out among the bridge-players and one of them exclaimed:

"Let's put it to d'Ormeval."

"Very well," said his adversary. "I'll accept his decision ... if he consents to act as umpire. He was rather huffy just now."

They called out:

"D'Ormeval! D'Ormeval!"

They then saw that d'Ormeval must have shut the door behind him, which kept him in the half dark, the cabin being one of the sort that has no window.

"He's asleep," cried one. "Let's wake him up."

All four went to the cabin, began by calling to him and, on receiving no answer, thumped on the door:

"Hi! D'Ormeval! Are you asleep?"

On the terrace Serge Renine suddenly leapt to his feet with so uneasy an air that Hortense was astonished. He muttered:

"If only it's not too late!"

And, when Hortense asked him what he meant, he tore down the steps and started running to the cabin. He reached it just as the bridge-players were trying to break in the door:

"Stop!" he ordered. "Things must be done in the regular fashion."

"What things?" they asked.

He examined the Venetian shutters at the top of each of the folding-doors and, on finding that one of the upper slats was partly broken, hung on as best he could to the roof of the cabin and cast a glance inside. Then he said to the four men:

"I was right in thinking that, if M. d'Ormeval did not reply, he must have been prevented by some serious cause. There is every reason to believe that M. d'Ormeval is wounded ... or dead."

"Dead!" they cried. "What do you mean? He has only just left us."

Renine took out his knife, prized open the lock and pulled back the two doors.

There were shouts of dismay. M. d'Ormeval was lying flat on his face, clutching his jacket and his newspaper in his hands. Blood was flowing from his back and staining his shirt.

"Oh!" said some one. "He has killed himself!"

"How can he have killed himself?" said Renine. "The wound is right in the middle of the back, at a place which the hand can't reach. And, besides, there's not a knife in the cabin."

The others protested:

"If so, he has been murdered. But that's impossible! There has been n.o.body here. We should have seen, if there had been. n.o.body could have pa.s.sed us without our seeing...."

The other men, all the ladies and the children paddling in the sea had come running up. Renine allowed no one to enter the cabin, except a doctor who was present. But the doctor could only say that M. d'Ormeval was dead, stabbed with a dagger.

At that moment, the mayor and the policeman arrived, together with some people of the village. After the usual enquiries, they carried away the body.

A few persons went on ahead to break the news to Therese d'Ormeval, who was once more to be seen on her balcony.

And so the tragedy had taken place without any clue to explain how a man, protected by a closed door with an uninjured lock, could have been murdered in the s.p.a.ce of a few minutes and in front of twenty witnesses, one might almost say, twenty spectators. No one had entered the cabin. No one had come out of it. As for the dagger with which M. d'Ormeval had been stabbed between the shoulders, it could not be traced. And all this would have suggested the idea of a trick of sleight-of-hand performed by a clever conjuror, had it not concerned a terrible murder, committed under the most mysterious conditions.

Hortense was unable to follow, as Renine would have liked, the small party who were making for Madame d'Ormeval; she was paralysed with excitement and incapable of moving. It was the first time that her adventures with Renine had taken her into the very heart of the action and that, instead of noting the consequences of a murder, or a.s.sisting in the pursuit of the criminals, she found herself confronted with the murder itself.
