"Indeed, yes," said Servettaz. "I might even have forgotten that I had not used it myself."

"Quite so," said Hanaud, and he turned to Besnard. "I think that may be important. I do not know," he said.

"But since the car is gone," cried Besnard, "how could the chauffeur not look immediately at his tins?"

The question had occurred to Ricardo, and he wondered in what way Hanaud meant to answer it. Hanaud, however, did not mean to answer it.

He took little notice of it at all. He put it aside with a superb indifference to the opinion which his companions might form of him.

"Ah, yes," he said, carelessly. "Since the car is gone, as you say, that is so." And he turned again to Servettaz.

"It was a powerful car?" he asked.

"Sixty horse-power," said Servettaz.

Hanaud turned to the Commissaire.

"You have the number and description, I suppose? It will be as well to advertise for it. It may have been seen; it must be somewhere."

The Commissaire replied that the description had already been printed, and Hanaud, with a nod of approval, examined the ground. In front of the garage there was a small stone courtyard, but on its surface there was no trace of a footstep.

"Yet the gravel was wet," he said, shaking his head. "The man who fetched that car fetched it carefully."

He turned and walked back with his eyes upon the ground. Then he ran to the gra.s.s border between the gravel and the bushes.

"Look!" he said to Wethermill; "a foot has pressed the blades of gra.s.s down here, but very lightly--yes, and there again. Some one ran along the border here on his toes. Yes, he was very careful."

They turned again into the main drive, and, following it for a few yards, came suddenly upon a s.p.a.ce in front of the villa. It was a small toy pleasure-house, looking on to a green lawn gay with flower-beds. It was built of yellow stone, and was almost square in shape. A couple of ornate pillars flanked the door, and a gable roof, topped by a gilt vane, surmounted it. To Ricardo it seemed impossible that so sordid and sinister a tragedy had taken place within its walls during the last twelve hours. It glistened so gaudily in the blaze of sunlight. Here and there the green outer shutters were closed; here and there the windows stood open to let in the air and light. Upon each side of the door there was a window lighting the hall, which was large; beyond those windows again, on each side, there were gla.s.s doors opening to the ground and protected by the ordinary green latticed shutters of wood, which now stood hooked back against the wall. These gla.s.s doors opened into rooms oblong in shape, which ran through towards the back of the house, and were lighted in addition by side windows. The room upon the extreme left, as the party faced the villa, was the dining-room, with the kitchen at the back; the room on the right was the salon in which the murder had been committed. In front of the gla.s.s door to this room a strip of what had once been gra.s.s stretched to the gravel drive. But the gra.s.s had been worn away by constant use, and the black mould showed through. This strip was about three yards wide, and as they approached they saw, even at a distance, that since the rain of last night it had been trampled down.

"We will go round the house first," said Hanaud, and he turned along the side of the villa and walked in the direction of the road. There were four windows just above his head, of which three lighted the salon, and the fourth a small writing-room behind it. Under these windows there was no disturbance of the ground, and a careful investigation showed conclusively that the only entrance used had been the gla.s.s doors of the salon facing the drive. To that spot, then, they returned. There were three sets of footmarks upon the soil. One set ran in a distinct curve from the drive to the side of the door, and did not cross the others.

"Those," said Hanaud, "are the footsteps of my intelligent friend, Perrichet, who was careful not to disturb the ground."

Perrichet beamed all over his rosy face, and Besnard nodded at him with condescending approval.

"But I wish, M. le Commissaire"--and Hanaud pointed to a blur of marks--"that your other officers had been as intelligent. Look! These run from the gla.s.s door to the drive, and, for all the use they are to us, a harrow might have been dragged across them."

Besnard drew himself up.

"Not one of my officers has entered the room by way of this door. The strictest orders were given and obeyed. The ground, as you see it, is the ground as it was at twelve o'clock last night."

Hanaud's face grew thoughtful.

"Is that so?" he said, and he stooped to examine the second set of marks. They were at the righthand side of the door. "A woman and a man," he said. "But they are mere hints rather than prints. One might almost think--" He rose up without finishing his sentence, and he turned to the third set and a look of satisfaction gleamed upon his face. "Ah! here is something more interesting," he said.

There were just three impressions; and, whereas the blurred marks were at the side, these three pointed straight from the middle of the gla.s.s doors to the drive. They were quite clearly defined, and all three were the impressions made by a woman's small, arched, high-heeled shoe. The position of the marks was at first sight a little peculiar. There was one a good yard from the window, the impression of the right foot, and the pressure of the sole of the shoe was more marked than that of the heel. The second, the impression of the left foot, was not quite so far from the first as the first was from the window, and here again the heel was the more lightly defined. But there was this difference--the mark of the toe, which was pointed in the first instance, was, in this, broader and a trifle blurred. Close beside it the right foot was again visible; only now the narrow heel was more clearly defined than the ball of the foot. It had, indeed, sunk half an inch into the soft ground. There were no further imprints. Indeed, these two were not merely close together, they were close to the gravel of the drive and on the very border of the gra.s.s.

Hanaud looked at the marks thoughtfully. Then he turned to the Commissaire.

"Are there any shoes in the house which fit those marks?"

"Yes. We have tried the shoes of all the women--Celie Harland, the maid, and even Mme. Dauvray. The only ones which fit at all are those taken from Celie Harland's bedroom."

He called to an officer standing in the drive, and a pair of grey suede shoes were brought to him from the hall.

"See, M. Hanaud, it is a pretty little foot which made those clear impressions," he said, with a smile; "a foot arched and slender. Mme.

Dauvray's foot is short and square, the maid's broad and flat. Neither Mme. Dauvray nor Helene Vauquier could have worn these shoes. They were lying, one here, one there, upon the floor of Celie Harland's room, as though she had kicked them off in a hurry. They are almost new, you see. They have been worn once, perhaps, no more, and they fit with absolute precision into those footmarks, except just at the toe of that second one."

Hanaud took the shoes and, kneeling down, placed them one after the other over the impressions. To Ricardo it was extraordinary how exactly they covered up the marks and filled the indentations.

"I should say," said the Commissaire, "that Celie Harland went away wearing a new pair of shoes made on the very same last as those."

As those she had left carelessly lying on the floor of her room for the first person to notice, thought Ricardo! It seemed as if the girl had gone out of her way to make the weight of evidence against her as heavy as possible. Yet, after all, it was just through inattention to the small details, so insignificant at the red moment of crime, so terribly instructive the next day, that guilt was generally brought home.

Hanaud rose to his feet and handed the shoes back to the officer.

"Yes," he said, "so it seems. The shoemaker can help us here. I see the shoes were made in Aix."

Besnard looked at the name stamped in gold letters upon the lining of the shoes.

"I will have inquiries made," he said.

Hanaud nodded, took a measure from his pocket and measured the ground between the window and the first footstep, and between the first footstep and the other two.

"How tall is Mlle. Celie?" he asked, and he addressed the question to Wethermill. It struck Ricardo as one of the strangest details in all this strange affair that the detective should ask with confidence for information which might help to bring Celia Harland to the guillotine from the man who had staked his happiness upon her innocence.

"About five feet seven," he answered.

Hanaud replaced his measure in his pocket. He turned with a grave face to Wethermill.

"I warned you fairly, didn't I?" he said.

Wethermill's white face twitched.

"Yes," he said. "I am not afraid." But there was more of anxiety in his voice than there had been before.

Hanaud pointed solemnly to the ground.

"Read the story those footprints write in the mould there. A young and active girl of about Mlle. Celie's height, and wearing a new pair of Mlle. Celie's shoes, springs from that room where the murder was committed, where the body of the murdered woman lies. She is running.

She is wearing a long gown. At the second step the hem of the gown catches beneath the point of her shoe. She stumbles. To save herself from falling she brings up the other foot sharply and stamps the heel down into the ground. She recovers her balance. She steps on to the drive. It is true the gravel here is hard and takes no mark, but you will see that some of the mould which has clung to her shoes has dropped off. She mounts into the motor-car with the man and the other woman and drives off--some time between eleven and twelve."

"Between eleven and twelve? Is that sure?" asked Besnard.

"Certainly," replied Hanaud. "The gate is open at eleven, and Perrichet closes it. It is open again at twelve. Therefore the murderers had not gone before eleven. No; the gate was open for them to go, but they had not gone. Else why should the gate again be open at midnight?"

Besnard nodded in a.s.sent, and suddenly Perrichet started forward, with his eyes full of horror.

"Then, when I first closed the gate," he cried, "and came into the garden and up to the house they were here--in that room? Oh, my G.o.d!"

He stared at the window, with his mouth open.
