"No!" cried Harry Wethermill.
Hanaud took no notice of the interruption.
"Secondly the woman came to the house with Mme. Dauvray and Mlle. Celie between nine and half-past nine. Thirdly, the man came afterwards, but before eleven, set open the gate, and was admitted into the salon, unperceived by Mme. Dauvray. That also we can safely assume. But what happened in the salon? Ah! There is the question." Then he shrugged his shoulders and said with the note of raillery once more in his voice:
"But why should we trouble our heads to puzzle out this mystery, since M. Ricardo knows?"
"I?" cried Ricardo in amazement.
"To be sure," replied Hanaud calmly. "For I look at another of your questions. 'WHAT DID THE TORN-UP SCRAP OF WRITING MEAN?' and you add: 'Probably spirit-writing.' Then there was a seance held last night in the little salon! Is that so?"
Harry Wethermill started. Mr. Ricardo was at a loss.
"I had not followed my suggestion to its conclusion," he admitted humbly.
"No," said Hanaud. "But I ask myself in sober earnest, 'Was there a seance held in the salon last night?' Did the tambourine rattle in the darkness on the wall?"
"But if Helene Vauquier’s story is all untrue?" cried Wethermill, again in exasperation.
"Patience, my friend. Her story was not all untrue. I say there were brains behind this crime; yes, but brains, even the cleverest, would not have invented this queer, strange story of the seances and of Mme. de Montespan. That is truth. But yet, if there were a seance held, if the scrap of paper were spirit-writing in answer to some awkward question, why-and here I come to my first question, which M. Ricardo has omitted-why did Mlle. Celie dress herself with so much elegance last night? What Vauquier said is true. Her dress was not suited to a seance. A light-coloured, rustling frock, which would be visible in a dim light, or even in the dark, which would certainly be heard at every movement she made, however lightly she stepped, and a big hat-no no! I tell you, gentlemen, we shall not get to the bottom of this mystery until we know why Mlle. Celie dressed herself as she did last night."Yes," Ricardo admitted. "I overlooked that point."Did she-" Hanaud broke off and bowed to Wethermill with a grace and a respect which condoned his words. "You must bear with me, my young friend, while I consider all these points. Did she expect to join that night a lover-a man with the brains to devise this crime? But if so-and here I come to the second question omitted from M. Ricardo’s list-why, on the patch of grass outside the door of the salon, were the footsteps of the man and woman so carefully erased, and the footsteps of Mlle. Celie-those little footsteps so easily identified-left for all the world to see and recognise?"
Ricardo felt like a child in the presence of his schoolmaster. He was convicted of presumption. He had set down his questions with the belief that they covered the ground. And here were two of the utmost importance, not forgotten, but never even thought of.
"Did she go, before the murder, to join a lover? Or after it? At some time, you will remember, according to Vauquier’s story, she must have run upstairs to fetch her coat. Was the murder committed during the interval when she was upstairs? Was the salon dark when she came down again? Did she run through it quickly, eagerly, noticing nothing amiss? And, indeed, how should she notice anything if the salon were dark, and Mme. Dauvray’s body lay under the windows at the side?"
Ricardo leaned forward eagerly.
"That must be the truth," he cried; and Wethermill’s voice broke hastily in:
"It is not the truth and I will tell you why. Celia Harland was to have married me this week."
There was so much pain and misery in his voice that Ricardo was moved as he had seldom been. Wethermill buried his face in his hands. Hanaud shook his head and gazed across the table at Ricardo with an expression which the latter was at no loss to understand. Lovers were impracticable people. But he-Hanaud-he knew the world. Women had fooled men before today.
Wethermill snatched his hands away from before his face.
"We talk theories," he cried desperately, "of what may have happened at the villa. But we are not by one inch nearer to the man and woman who committed the crime. It is for them we have to search."
"Yes; but except by asking ourselves questions, how shall we find them, M. Wethermill?" said Hanaud. "Take the man! We know nothing of him. He has left no trace. Look at this town of Aix, where people come and go like a crowd about the baccarat-table! He may be at Marseilles today. He may be in this very room where we are taking our luncheon. How shall we find him?"
Wethermill nodded his head in a despairing assent.
"I know. But it is so hard to sit still and do nothing," he cried.
"Yes, but we are not sitting still," said Hanaud; and Wethermill looked up with a sudden interest. "All the time that we have been lunching here the intelligent Perrichet has been making inquiries. Mme. Dauvray and Mlle. Celie left the Villa Rose at five, and returned on foot soon after nine with the strange woman. And there I see Perrichet himself waiting to be summoned."
Hanaud beckoned towards the sergent-de-ville.
"Perrichet will make an excellent detective," he said; "for he looks more bovine and foolish in plain clothes than he does in uniform."
Perrichet advanced in his mufti to the table.
"Speak, my friend," said Hanaud.
"I went to the shop of M. Corval. Mlle. Celie was quite alone when she bought the cord. But a few minutes later, in the Rue du Casino, she and Mme. Dauvray were seen together, walking slowly in the direction of the villa. No other woman was with them."
"That is a pity," said Hanaud quietly, and with a gesture he dismissed Perrichet.
"You see, we shall find out nothing-nothing," said Wethermill, with a groan.
"We must not yet lose heart, for we know a little more about the woman than we do about the man," said Hanaud consolingly.
"True," exclaimed Ricardo. "We have Helene Vauquier’s description of her. We must advertise it."
Hanaud smiled.
"But that is a fine suggestion," he cried. "We must think over that," and he clapped his hand to his forehead with a gesture of self-reproach. "Why did not such a fine idea occur to me, fool that I am! However, we will call the head waiter."
The head waiter was sent for and appeared before them.
"You knew Mme. Dauvray?" Hanaud asked.
"Yes, monsieur-oh, the poor woman! And he flung up his hands."
"And you knew her young companion?"
"Oh yes, monsieur. They generally had their meals here. See, at that little table over there! I kept it for them. But monsieur knows well"-and the waiter looked towards Harry Wethermill-"for monsieur was often with them."
"Yes," said Hanaud. "Did Mme. Dauvray dine at that little table last night?"
"No, monsieur. She was not here last night."
"Nor Mlle. Celie?"
"No, monsieur! I do not think they were in the Villa des Fleurs at all."
"We know they were not," exclaimed Ricardo. "Wethermill and I were in the rooms and we did not see them."
"But perhaps you left early," objected Hanaud.
"No," said Ricardo. "It was just ten o’clock when we reached the Majestic."
"You reached your hotel at ten," Hanaud repeated. "Did you walk straight from here?"
"Yes."
"Then you left here about a quarter to ten. And we know that Mme. Dauvray was back at the villa soon after nine. Yes-they could not have been here last night," Hanaud agreed, and sat for a moment silent. Then he turned to the head waiter.
