But he went further yet. The populace had been supposed to be disarmed ever since the suppression of the revolt, but Otto now insisted, as governments very seldom insist, on an absolute and literal disarmament.
It was carried out, with extraordinary thoroughness and severity, by very well-organized officials over a small and familiar area, and, so far as human strength and science can be absolutely certain of anything, Prince Otto was absolutely certain that nobody could introduce so much as a toy pistol into Heiligwaldenstein."
"Human science can never be quite certain of things like that," said Father Brown, still looking at the red budding of the branches over his head, "if only because of the difficulty about definition and connotation. What is a weapon? People have been murdered with the mildest domestic comforts; certainly with tea-kettles, probably with tea-cosies. On the other hand, if you showed an Ancient Briton a revolver, I doubt if he would know it was a weapon-- until it was fired into him, of course. Perhaps somebody introduced a firearm so new that it didn't even look like a firearm.
Perhaps it looked like a thimble or something. Was the bullet at all peculiar?"
"Not that I ever heard of," answered Flambeau; "but my information is fragmentary, and only comes from my old friend Grimm.
He was a very able detective in the German service, and he tried to arrest me; I arrested him instead, and we had many interesting chats.
He was in charge here of the inquiry about Prince Otto, but I forgot to ask him anything about the bullet. According to Grimm, what happened was this." He paused a moment to drain the greater part of his dark lager at a draught, and then resumed:
"On the evening in question, it seems, the Prince was expected to appear in one of the outer rooms, because he had to receive certain visitors whom he really wished to meet. They were geological experts sent to investigate the old question of the alleged supply of gold from the rocks round here, upon which (as it was said) the small city-state had so long maintained its credit and been able to negotiate with its neighbours even under the ceaseless bombardment of bigger armies.
Hitherto it had never been found by the most exacting inquiry which could--"
"Which could be quite certain of discovering a toy pistol," said Father Brown with a smile. "But what about the brother who ratted?
Hadn't he anything to tell the Prince?"
"He always asseverated that he did not know," replied Flambeau;"that this was the one secret his brothers had not told him.
It is only right to say that it received some support from fragmentary words--spoken by the great Ludwig in the hour of death, when he looked at Heinrich but pointed at Paul, and said, `You have not told him...' and was soon afterwards incapable of speech.
Anyhow, the deputation of distinguished geologists and mineralogists from Paris and Berlin were there in the most magnificent and appropriate dress, for there are no men who like wearing their decorations so much as the men of science--as anybody knows who has ever been to a soiree of the Royal Society. It was a brilliant gathering, but very late, and gradually the Chamberlain--you saw his portrait, too: a man with black eyebrows, serious eyes, and a meaningless sort of smile underneath--the Chamberlain, I say, discovered there was everything there except the Prince himself. He searched all the outer salons; then, remembering the man's mad fits of fear, hurried to the inmost chamber. That also was empty, but the steel turret or cabin erected in the middle of it took some time to open.
When it did open it was empty, too. He went and looked into the hole in the ground, which seemed deeper and somehow all the more like a grave--that is his account, of course. And even as he did so he heard a burst of cries and tumult in the long rooms and corridors without.
"First it was a distant din and thrill of something unthinkable on the horizon of the crowd, even beyond the castle. Next it was a wordless clamour startlingly close, and loud enough to be distinct if each word had not killed the other. Next came words of a terrible clearness, coming nearer, and next one man, rushing into the room and telling the news as briefly as such news is told.
"Otto, Prince of Heiligwaldenstein and Grossenmark, was lying in the dews of the darkening twilight in the woods beyond the castle, with his arms flung out and his face flung up to the moon.
The blood still pulsed from his shattered temple and jaw, but it was the only part of him that moved like a living thing.
He was clad in his full white and yellow uniform, as to receive his guests within, except that the sash or scarf had been unbound and lay rather crumpled by his side. Before he could be lifted he was dead.
But, dead or alive, he was a riddle--he who had always hidden in the inmost chamber out there in the wet woods, unarmed and alone."
"Who found his body?" asked Father Brown.
"Some girl attached to the Court named Hedwig von something or other," replied his friend, "who had been out in the wood picking wild flowers."
"Had she picked any?" asked the priest, staring rather vacantly at the veil of the branches above him.
"Yes," replied Flambeau. "I particularly remember that the Chamberlain, or old Grimm or somebody, said how horrible it was, when they came up at her call, to see a girl holding spring flowers and bending over that--that bloody collapse. However, the main point is that before help arrived he was dead, and the news, of course, had to be carried back to the castle. The consternation it created was something beyond even that natural in a Court at the fall of a potentate.
The foreign visitors, especially the mining experts, were in the wildest doubt and excitement, as well as many important Prussian officials, and it soon began to be clear that the scheme for finding the treasure bulked much bigger in the business than people had supposed.
