'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. Experts and officials had been promised great prizes or international advantages, and some even said that the Prince's secret apartments and strong military protection were due less to fear of the populace than to the pursuit of some private investigation of—'
'Had the flowers got long stalks?' asked Father Brown.
Flambeau stared at him. 'What an odd person you are!' he said. 'That's exactly what old Grimm said. He said the ugliest part of it, he thought—uglier than the blood and bullet—was that the flowers were quite short, plucked close under the head.'
'Of course,' said the priest, 'when a grown up girl is really picking flowers, she picks them with plenty of stalk. If she just pulled their heads off, as a child does, it looks as if—' And he hesitated.
'Well?' inquired the other.
'Well, it looks rather as if she had snatched them nervously, to make an excuse for being there after—well, after she was there.'
'I know what you're driving at,' said Flambeau rather gloomily. 'But that and every other suspicion breaks down on the one point—the want of a weapon. He could have been killed, as you say, with lots of other things— even with his own military sash; but we have to explain not how he was killed, but how he was shot. And the fact is we can't. They had the girl most ruthlessly searched; for, to tell the truth, she was a little suspect, though the niece and ward of the wicked old Chamberlain, Paul Arnhold. But she was very romantic, and was suspected of sympathy with the old revolutionary enthusiasm in her family. All the same, however romantic you are, you can't imagine a big bullet into a man's jaw or brain without using a gun or pistol. And there was no pistol, though there were two pistol shots. I leave it to you, my friend.'
'How do you know there were two shots?' asked the little priest.
'There was only one in his head,' said his companion, 'but there was another bullet-hole in the sash.'
Father Brown's smooth brow became suddenly constricted. 'Was the other bullet found?' he demanded.
Flambeau started a little. 'I don't think I remember,' he said.
'Hold on! Hold on! Hold on!' cried Brown, frowning more and more, with a quite unusual concentration of curiosity. 'Don't think me rude. Let me think this out for a moment.'
'All right,' said Flambeau, laughing, and finished his beer. A slight breeze stirred the budding trees and blew up into the sky cloudlets of white and pink that seemed to make the sky bluer and the whole coloured scene more quaint. They might have been cherubs flying home to the casements of a sort of celestial nursery. The oldest tower of the castle, the Dragon Tower , stood up as grotesque as the ale-mug, but as homely. Only beyond the tower glimmered the wood in which the man had lain dead.
'What became of this Hedwig eventually?' asked the priest at last.
'She is married to General Schwartz,' said Flambeau. 'No doubt you've heard of his career, which was rather romantic. He had distinguished himself even, before his exploits at Sadowa and Gravelotte; in fact, he rose from the ranks, which is very unusual even in the smallest of the German…' Father Brown sat up suddenly.
'Rose from the ranks!' he cried, and made a mouth as if to whistle. 'Well, well, what a queer story! What a queer way of killing a man; but I suppose it was the only one possible. But to think of hate so patient—'
'What do you mean?' demanded the other. 'In what way did they kill the man?'
'They killed him with the sash,' said Brown carefully; and then, as Flambeau protested: 'Yes, yes, I know about the bullet. Perhaps I ought to say he died of having a sash. I know it doesn't sound like having a disease.'
'I suppose,' said Flambeau, 'that you've got some notion in your head, but it won't easily get the bullet out of his. As I explained before, he might easily have been strangled. But he was shot. By whom? By what?'
'He was shot by his own orders,' said the priest.
'You mean he committed suicide?'
'I didn't say by his own wish,' replied Father Brown. 'I said by his own orders.'
'Well, anyhow, what is your theory?'
Father Brown laughed. 'I am only on my holiday,' he said. 'I haven't got any theories. Only this place reminds me of fairy stories, and, if you like, I'll tell you a story.'
The little pink clouds, that looked rather like sweet-stuff, had floated up to crown the turrets of the gilt gingerbread castle, and the pink baby fingers of the budding trees seemed spreading and stretching to reach them; the blue sky began to take a bright violet of evening, when Father Brown suddenly spoke again:
'It was on a dismal night, with rain still dropping from the trees and dew already clustering, that Prince Otto of Grossenmark stepped hurriedly out of a side door of the castle and walked swiftly into the wood. One of the innumerable sentries saluted him, but he did not notice it. He had no wish to be specially noticed himself. He was glad when the great trees, grey and already greasy with rain, swallowed him up like a swamp. He had deliberately chosen the least frequented side of his palace, but even that was more frequented than he liked. But there was no particular chance of officious or diplomatic pursuit, for his exit had been a sudden impulse. All the full-dressed diplomatists he left behind were unimportant. He had realized suddenly that he could do without them.
'His great passion was not the much nobler dread of death, but the strange desire of gold. For this legend of the gold he had left Grossenmark and invaded Heiligwaldenstein. For this and only this he had bought the traitor
