'Father Brown,' said the secretary, who had recovered his quiet tone, 'you're very smart, but there's something more to you than smartness. Somehow you're the sort of man to whom one wants to tell the truth; and besides, you'll probably hear it, anyhow, for in one way it's a joke against me already. They all say I'm a monomaniac about running down this big crook, and perhaps I am. But I'll tell you one thing that none of them know. My full name is John Wilton Horder.' Father Brown nodded as if he were completely enlightened, but the other went on.
'This fellow who calls himself Doom killed my father and uncle and ruined my mother. When Merton wanted a secretary I took the job, because I thought that where the cup was the criminal might sooner or later be. But I didn't know who the criminal was and could only wait for him; and I meant to serve Merton faithfully.'
'I understand,' said Father Brown gently; 'and, by the way, isn't it time that we attended on him?'
'Why, yes,' answered Wilton , again starting a little out of his brooding so that the priest concluded that his vindictive mania had again absorbed him for a moment.' Go in now by all means.'
Father Brown walked straight into the inner room. No sound of greetings followed, but only a dead silence; and a moment after the priest reappeared in the doorway.
At the same moment the silent bodyguard sitting near the door moved suddenly; and it was as if a huge piece of furniture had come to life. It seemed as though something in the very attitude of the priest had been a signal; for his head was against the light from the inner window and his face was in shadow.
'I suppose you will press that button,' he said with a sort of sigh.
Wilton seemed to awake from his savage brooding with a bound and leapt up with a catch in his voice.
'There was no shot,' he cried.
'Well,' said Father Brown, 'it depends what you mean by a shot.'
Wilton rushed forward, and they plunged into the inner room together. It was a comparatively small room and simply though elegantly furnished. Opposite to them one wide window stood open, over–looking the garden and the wooded plain. Close up against the window stood a chair and a small table, as if the captive desired as much air and light as was allowed him during his brief luxury of loneliness.
On the little table under the window stood the Coptic Cup; its owner had evidently been looking at it in the best light. It was well worth looking at, for that white and brilliant daylight turned its precious stones to many–coloured flames so that it might have been a model of the Holy Grail. It was well worth looking at; but Brander Merton was not looking at it. For his head had fallen back over his chair, his mane of white hair hanging towards the floor, and his spike of grizzled beard thrust up towards the ceiling, and out of his throat stood a long, brown–painted arrow with red leathers at the other end.
'A silent shot,' said Father Brown, in a low voice; 'I was just wondering about those new inventions for silencing firearms. But this is a very old invention, and quite as silent.'
Then, after a moment, he added: 'I'm afraid he is dead. What are you going to do?'
The pale secretary roused himself with abrupt resolution. 'I'm going to press that button, of course,' he said, 'and if that doesn't do for Daniel Doom, I'm going to hunt him through the world till I find him.'
'Take care it doesn't do for any of our friends,' observed Father Brown; 'they can hardly be far off; we'd better call them.'
'That lot know all about the wall,' answered Wilton. 'None of them will try to climb it, unless one of them … is in a great hurry.'
Father Brown went to the window by which the arrow had evidently entered and looked out. The garden, with its flat flower–beds, lay far below like a delicately coloured map of the world. The whole vista seemed so vast and empty, the tower seemed set so far up in the sky that as he stared out a strange phrase came back to his memory.
'A bolt from the blue,' he said. 'What was that somebody said about a bolt from the blue and death coming out of the sky? Look how far away everything looks; it seems extraordinary that an arrow could come so far, unless it were an arrow from heaven.'
Wilton had returned, but did not reply, and the priest went on as in soliloquy. 'One thinks of aviation. We must ask young Wain … about aviation.'
'There's a lot of it round here,' said the secretary.
'Case of very old or very new weapons,' observed Father Brown. 'Some would be quite familiar to his old uncle, I suppose; we must ask him about arrows. This looks rather like a Red Indian arrow. I don't know where the Red Indian shot it from; but you remember the story the old man told. I said it had a moral.'
'If it had a moral,' said Wilton warmly, 'it was only that a real 'Red Indian might shoot a thing farther than you'd fancy. It's nonsense your suggesting a parallel.'
'I don't think you've got the moral quite right,' said Father Brown.
Although the little priest appeared to melt into the millions of New York next day, without any apparent attempt to be anything but a number in a numbered street, he was, in fact, unobtrusively busy for the next fortnight with the commission that had been given him, for he was filled with profound fear about a possible miscarriage of justice. Without having any particular air of singling them out from his other new acquaintances, he found it easy to fall into talk with the two or three men recently involved in the mystery; and with old Hickory Crake especially he had a curious and interesting conversation. It took place on a seat in Central Park , where the veteran sat with his bony hands and hatchet face resting on the oddly–shaped head of a walking–stick of dark red wood, possibly modelled on a tomahawk.
'Well, it may be a long shot,' he said, wagging his head, 'but I wouldn't advise you to be too positive about how far an Indian arrow could go. I've known some bow–shots that seemed to go straighter than any bullets, and hit the mark to amazement, considering how long they had been travelling. Of course, you practically never hear now of a Red Indian with a bow and arrows, still less of a Red Indian hanging about here. But if by any chance there were one of the old Indian marksmen, with one of the old Indian bows, hiding in those trees hundreds of yards beyond the Merton outer wall–why, then I wouldn't put it past the noble savage to be able to send an arrow over the wall and into the top window of Merton's house; no, nor into Merton, either. I've seen things quite as wonderful as that done in the old days.'
'No doubt,' said the priest, 'you have done things quite as wonderful, as well as seen them.'
Old Crake chuckled, and then said gruffly: 'Oh, that's all ancient history.'
'Some people have a way of studying ancient history,' the priest said. 'I suppose we may take it there is nothing in your old record to make people talk unpleasantly about this affair.'
'What do you mean?' demanded Crake, his eyes shifting sharply for the first time, in his red, wooden face, that was rather like I he head of a tomahawk.
'Well, since you were so well acquainted with all the arts and crafts of the Redskin–' began Father Brown slowly.
Crake had had a hunched and almost shrunken appearance as he sat with his chin propped on its queer–shaped crutch. But the next instant he stood erect in the path like a fighting bravo with the crutch clutched like a cudgel.
'What?' he cried–in something like a raucous screech–'what the hell! Are you standing up to me to tell me I might happen to have murdered my own brother–in–law?'
