that of some horrible malady. As March moved he started violently and faced round.
"My God!" he cried, "have you seen what's outside?"
"Outside?" repeated the other, glancing over his shoulder at the garden.
"Oh, go and look for yourself," cried Herries in a sort of fury. "Hewitt's murdered and his papers stolen, that's all."
He turned his back again and sat down with a thud; his square shoulders were shaking. Harold March darted out of the doorway into the back garden with its steep slope of statues.
The first thing he saw was Doctor Prince, the detective, peering through his spectacles at something on the ground; the second was the thing he was peering at. Even after the sensational news he had heard inside, the sight was something of a sensation.
The monstrous stone image of Britannia was lying prone and face downward on the garden path; and there stuck out at random from underneath it, like the legs of a smashed fly, an arm clad in a white shirt sleeve and a leg clad in a khaki trouser, and hair of the unmistakable sandy gray that belonged to Horne Fisher's unfortunate uncle. There were pools of blood and the limbs were quite stiff in death.
"Couldn't this have been an accident?" said March, finding words at last.
"Look for yourself, I say," repeated the harsh voice of Herries, who had followed him with restless movements out of the door. "The papers are gone, I tell you. The fellow tore the coat off the corpse and cut the papers out of the inner pocket. There's the coat over there on the bank, with the great slash in it."
"But wait a minute," said the detective, Prince, quietly. "In that case there seems to be something of a mystery. A murderer might somehow have managed to throw the statue down on him, as he seems to have done. But I bet he couldn't easily have lifted it up again. I've tried; and I'm sure it would want three men at least. Yet we must suppose, on that theory, that the murderer first knocked him down as he walked past, using the statue as a stone club, then lifted it up again, took him out and deprived him of his coat, then put him back again in the posture of death and neatly replaced the statue. I tell you it's physically impossible. And how else could he have unclothed a man covered with that stone monument? It's worse than the conjurer's trick, when a man shuffles a coat off with his wrists tied."
"Could he have thrown down the statue after he'd stripped the corpse?" asked March.
"And why?" asked Prince, sharply. "If he'd killed his man and got his papers, he'd be away like the wind. He wouldn't potter about in a garden excavating the pedestals of statues. Besides—Hullo, who's that up there?"
High on the ridge above them, drawn in dark thin lines against the sky, was a figure looking so long and lean as to be almost spidery. The dark silhouette of the head showed two small tufts like horns; and they could almost have sworn that the horns moved.
"Archer!" shouted Herries, with sudden passion, and called to him with curses to come down. The figure drew back at the first cry, with an agitated movement so abrupt as almost to be called an antic. The next moment the man seemed to reconsider and collect himself, and began to come down the zigzag garden path, but with obvious reluctance, his feet falling in slower and slower rhythm. Through March's mind were throbbing the phrases that this man himself had used, about going mad in the middle of the night and wrecking the stone figure. Just so, he could fancy, the maniac who had done such a thing might climb the crest of the hill, in that feverish dancing fashion, and look down on the wreck he had made. But the wreck he had made here was not only a wreck of stone.
When the man emerged at last on to the garden path, with the full light on his face and figure, he was walking slowly indeed, but easily, and with no appearance of fear.
"This is a terrible thing," he said. "I saw it from above; I was taking a stroll along the ridge."
"Do you mean that you saw the murder?" demanded March, "or the accident? I mean did you see the statue fall?"
"No," said Archer, "I mean I saw the statue fallen."
Prince seemed to be paying but little attention; his eye was riveted on an object lying on the path a yard or two from the corpse. It seemed to be a rusty iron bar bent crooked at one end.
"One thing I don't understand," he said, "is all this blood. The poor fellow's skull isn't smashed; most likely his neck is broken; but blood seems to have spouted as if all his arteries were severed. I was wondering if some other instrument … that iron thing, for instance; but I don't see that even that is sharp enough. I suppose nobody knows what it is."
"I know what it is," said Archer in his deep but somewhat shaky voice. "I've seen it in my nightmares. It was the iron clamp or prop on the pedestal, stuck on to keep the wretched image upright when it began to wobble, I suppose. Anyhow, it was always stuck in the stonework there; and I suppose it came out when the thing collapsed."
Doctor Prince nodded, but he continued to look down at the pools of blood and the bar of iron.
"I'm certain there's something more underneath all this," he said at last. "Perhaps something more underneath the statue. I have a huge sort of hunch that there is. We are four men now and between us we can lift that great tombstone there."
They all bent their strength to the business; there was a silence save for heavy breathing; and then, after an instant of the tottering and staggering of eight legs, the great carven column of rock was rolled away, and the body lying in its shirt and trousers was fully revealed. The spectacles of Doctor Prince seemed almost to enlarge with a restrained radiance like great eyes; for other things were revealed also. One was that the unfortunate Hewitt had a deep gash across the jugular, which the triumphant doctor instantly identified as having been made with a sharp steel edge like a razor. The other was that immediately under the bank lay littered three shining scraps of steel, each nearly a foot long, one pointed and another fitted into a gorgeously jeweled hilt or handle. It was evidently a sort of long Oriental knife, long enough to be called a sword, but with a curious wavy edge; and there was a touch or two of blood on the point.
"I should have expected more blood, hardly on the point," observed Doctor Prince, thoughtfully, "but this is certainly the instrument. The slash was certainly made with a weapon shaped like this, and probably the slashing of the pocket as well. I suppose the brute threw in the statue, by way of giving him a public funeral."
March did not answer; he was mesmerized by the strange stones that glittered on the strange sword hilt; and their possible significance was broadening upon him like a dreadful dawn. It was a curious Asiatic weapon. He knew what name was connected in his memory with curious Asiatic weapons. Lord James spoke his secret thought for him, and yet it startled him like an irrelevance.
"Where is the Prime Minister?" Herries had cried, suddenly, and somehow like the bark of a dog at some discovery.
Doctor Prince turned on him his goggles and his grim face; and it was grimmer than ever.
"I cannot find him anywhere," he said. "I looked for him at once, as soon as I found the papers were gone. That servant of yours, Campbell, made a most efficient search, but there are no traces."
There was a long silence, at the end of which Herries uttered another cry, but upon an entirely new note.
"Well, you needn't look for him any longer," he said, "for here he comes, along with your friend Fisher. They look as if they'd been for a little walking tour."
The two figures approaching up the path were indeed those of Fisher, splashed with the mire of travel and carrying a
