"But why?" she insisted.
"What is the nursery-rhyme?" observed Brown absent-mindedly. "There was a crooked man and he went a crooked mile… . That man, I fancy, has gone a very crooked road—by following his nose."
"Why, what's he done?" she demanded, rather shakily.
"I don't want to force your confidence by a hair," said Father Brown, very quietly. "But I think you could tell me more about that than I can tell you."
The girl sprang to her feet and stood quite quietly, but with clenched hands, like one about to stride away; then her hands loosened slowly, and she sat down again. "You are more of a mystery than all the others," she said desperately, "but I feel there might be a heart in your mystery."
"What we all dread most," said the priest in a low voice, "is a maze with no centre. That is why atheism is only a nightmare." "I will tell you everything," said the red-haired girl doggedly, "except why I am telling you; and that I don't know."
She picked at the darned table-cloth and went on: "You look as if you knew what isn't snobbery as well as what is; and when I say that ours is a good old family, you'll understand it is a necessary part of the story; indeed, my chief danger is in my brother's high-and-dry notions, noblesse oblige and all that. Well, my name is Christabel Carstairs; and my father was that Colonel Carstairs you've probably heard of, who made the famous Carstairs Collection of Roman coins. I could never describe my father to you; the nearest I can say is that he was very like a Roman coin himself. He was as handsome and as genuine and as valuable and as metallic and as out-of-date. He was prouder of his Collection than of his coat-of-arms—nobody could say more than that. His extraordinary character came out most in his will. He had two sons and one daughter. He quarrelled with one son, my brother Giles, and sent him to Australia on a small allowance. He then made a will leaving the Carstairs Collection, actually with a yet smaller allowance, to my brother Arthur. He meant it as a reward, as the highest honour he could offer, in acknowledgement of Arthur's loyalty and rectitude and the distinctions he had already gained in mathematics and economics at Cambridge. He left me practically all his pretty large fortune; and I am sure he meant it in contempt.
"Arthur, you may say, might well complain of this; but Arthur is my father over again. Though he had some differences with my father in early youth, no sooner had he taken over the Collection than he became like a pagan priest dedicated to a temple. He mixed up these Roman halfpence with the honour of the Carstairs family in the same stiff, idolatrous way as his father before him. He acted as if Roman money must be guarded by all the Roman virtues. He took no pleasures; he spent nothing on himself; he lived for the Collection. Often he would not trouble to dress for his simple meals; but pattered about among the corded brown-paper parcels (which no one else was allowed to touch) in an old brown dressing-gown. With its rope and tassel and his pale, thin, refined face, it made him look like an old ascetic monk. Every now and then, though, he would appear dressed like a decidedly fashionable gentleman; but that was only when he went up to the London sales or shops to make an addition to the Carstairs Collection.
"Now, if you've known any young people, you won't be shocked if I say that I got into rather a low frame of mind with all this; the frame of mind in which one begins to say that the Ancient Romans were all very well in their way. I'm not like my brother Arthur; I can't help enjoying enjoyment. I got a lot of romance and rubbish where I got my red hair, from the other side of the family. Poor Giles was the same; and I think the atmosphere of coins might count in excuse for him; though he really did wrong and nearly went to prison. But he didn't behave any worse than I did; as you shall hear.
"I come now to the silly part of the story. I think a man as clever as you can guess the sort of thing that would begin to relieve the monotony for an unruly girl of seventeen placed in such a position. But I am so rattled with more dreadful things that I can hardly read my own feeling; and don't know whether I despise it now as a flirtation or bear it as a broken heart. We lived then at a little seaside watering-place in South Wales, and a retired sea-captain living a few doors off had a son about five years older than myself, who had been a friend of Giles before he went to the Colonies. His name does not affect my tale; but I tell you it was Philip Hawker, because I am telling you everything. We used to go shrimping together, and said and thought we were in love with each other; at least he certainly said he was, and I certainly thought I was. If I tell you he had bronzed curly hair and a falconish sort of face, bronzed by the sea also, it's not for his sake, I assure you, but for the story; for it was the cause of a very curious coincidence.
"One summer afternoon, when I had promised to go shrimping along the sands with Philip, I was waiting rather impatiently in the front drawing-room, watching Arthur handle some packets of coins he had just purchased and slowly shunt them, one or two at a time, into his own dark study and museum which was at the back of the house. As soon as I heard the heavy door close on him finally, I made a bolt for my shrimping-net and tam-o'-shanter and was just going to slip out, when I saw that my brother had left behind him one coin that lay gleaming on the long bench by the window. It was a bronze coin, and the colour, combined with the exact curve of the Roman nose and something in the very lift of the long, wiry neck, made the head of Caesar on it the almost precise portrait of Philip Hawker. Then I suddenly remembered Giles telling Philip of a coin that was like him, and Philip wishing he had it. Perhaps you can fancy the wild, foolish thoughts with which my head went round; I felt as if I had had a gift from the fairies. It seemed to me that if I could only run away with this, and give it to Philip like a wild sort of wedding-ring, it would be a bond between us for ever; I felt a thousand such things at once. Then there yawned under me, like the pit, the enormous, awful notion of what I was doing; above all, the unbearable thought, which was like touching hot iron, of what Arthur would think of it. A Carstairs a thief; and a thief of the Carstairs treasure! I believe my brother could see me burned like a witch for such a thing, But then, the very thought of such fanatical cruelty heightened my old hatred of his dingy old antiquarian fussiness and my longing for the youth and liberty that called to me from the sea. Outside was strong sunlight with a wind; and a yellow head of some broom or gorse in the garden rapped against the glass of the window. I thought of that living and growing gold calling to me from all the heaths of the world—and then of that dead, dull gold and bronze and brass of my brother's growing dustier and dustier as life went by. Nature and the Carstairs Collection had come to grips at last.
"Nature is older than the Carstairs Collection. As I ran down the streets to the sea, the coin clenched tight in my fist, I felt all the Roman Empire on my back as well as the Carstairs pedigree. It was not only the old lion argent that was roaring in my ear, but all the eagles of the Caesars seemed flapping and screaming in pursuit of me. And yet my heart rose higher and higher like a child's kite, until I came over the loose, dry sand-hills and to the flat, wet sands, where Philip stood already up to his ankles in the shallow shining water, some hundred yards out to sea. There was a great red sunset; and the long stretch of low water, hardly rising over the ankle for half a mile, was like a lake of ruby flame. It was not till I had torn off my shoes and stockings and waded to where he stood, which was well away from the dry land, that I turned and looked round. We were quite alone in a circle of sea-water and wet sand, and I gave him the head of Caesar.
"At the very instant I had a shock of fancy: that a man far away on the sand-hills was looking at me intently. I must have felt immediately after that it was a mere leap of unreasonable nerves; for the man was only a dark dot in the distance, and I could only just see that he was standing quite still and gazing, with his head a little on one side. There was no earthly logical evidence that he was looking at me; he might have been looking at a ship, or the sunset, or the sea-gulls, or at any of the people who still strayed here and there on the shore between us. Nevertheless, whatever my start sprang from was prophetic; for, as I gazed, he started walking briskly in a bee-line towards us across the wide wet sands. As he drew nearer and nearer I saw that he was dark and bearded, and that his eyes were marked with dark spectacles. He was dressed poorly but respectably in black, from the old black top hat on his head to the solid black boots on his feet. In spite of these he walked straight into the sea without a flash of hesitation, and came on at me with the steadiness of a travelling bullet.
"I
