“And what did he do?” asked the lawyer.
“He killed his father,” answered the priest.
The lawyer in his turn rose from his seat and gazed across the table with wrinkled brows.
“But his father is at the castle,” he cried in sharp tones.
“His father is in the moat,” said the priest, “and I was a fool not to have known it from the first when something bothered me about that suit of armour. Don’t you remember the look of that room? How very carefully it was arranged and decorated? There were two crossed battle-axes hung on one side of the fireplace, two crossed battle-axes on the other. There was a round Scottish shield on one wall, a round Scottish shield on the other. And there was a stand of armour guarding one side of the hearth, and an empty space on the other. Nothing will make me believe that a man who arranged all the rest of that room with that exaggerated symmetry left that one feature of it lopsided. There was almost certainly another man in armour. And what has become of him?”
He paused a moment, and then went on in a more matter-of-fact tone:
“When you come to think of it, it’s a very good plan for a murder, and meets the permanent problem of the disposal of the body. The body could stand inside that complete tilting-armour for hours, or even days, while servants came and went, until the murderer could simply drag it out in the dead of night and lower it into the moat, without even crossing the bridge. And then what a good chance he ran! As soon as the body was at all decayed in the stagnant water there would sooner or later be nothing but a skeleton in fourteenth-century armour, a thing very likely to be found in the moat of an old Border castle. It was unlikely that anybody would look for anything there, but if they did, that would soon be all they would find. And I got some confirmation of that. That was when you said I was looking for a rare plant; it was a plant in a good many senses, if you’ll excuse the jest. I saw the marks of two feet sunk so deep into the solid bank I was sure that the man was either very heavy or was carrying something very heavy. Also, by the way, there’s another moral from that little incident when I made my celebrated graceful and catlike leap.”
“My brain is rather reeling,” said Granby, “but I begin to have some notion of what all this nightmare is about. What about you and your catlike leap?”
“At the post office today,” said Father Brown, “I casually confirmed the statement the baronet made to me yesterday, that he had been there just after closing-time on the day previous—that is, not only on the very day we arrived, but at the very time we arrived. Don’t you see what that means? It means that he was actually out when we called, and came back while we were waiting; and that was why we had to wait so long. And when I saw that, I suddenly saw a picture that told the whole story.”
“Well,” asked the other impatiently, “and what about it?”
“An old man of eighty can walk,” said Father Brown. “An old man can even walk a good deal, pottering about in country lanes. But an old man can’t jump. He would be an even less graceful jumper than I was. Yet, if the baronet came back while we were waiting, he must have come in as we came in—by jumping the moat—for the bridge wasn’t lowered till later. I rather guess he had hampered it himself to delay inconvenient visitors, to judge by the rapidity with which it was repaired. But that doesn’t matter. When I saw that fancy picture of the black figure with the grey hair taking a flying leap across the moat I knew instantly that it was a young man dressed up as an old man. And there you have the whole story.”
“You mean,” said Granby slowly, “that this pleasing youth killed his father, hid the corpse first in the armour and then in the moat, disguised himself, and so on?”
“They happened to be almost exactly alike,” said the priest. “You could see from the family portraits how strong the likeness ran. And then you talk of his disguising himself. But in a sense everybody’s dress is a disguise. The old man disguised himself in a wig, and the young man in a foreign beard. When he shaved and put the wig on his cropped head he was exactly like his father, with a little makeup. Of course, you understand now why he was so very polite about getting you to come up next day here by car. It was because he himself was coming up that night by train. He got in front of you, committed his crime, assumed his disguise, and was ready for the legal negotiations.”
“Ah,” said Granby thoughtfully, “the legal negotiations! You mean, of course, that the real old baronet would have negotiated very differently.”
“He would have told you plainly that the Captain would never get a penny,” said Father Brown. “The plot, queer as it sounds, was really the only way of preventing his telling you so. But I want you to appreciate the cunning of what the fellow did tell you. His plan answered several purposes at once. He was being blackmailed by these Russians for some villainy; I suspect for treason during the war. He escaped from them at a stroke, and probably sent them chasing off to Riga after him. But the most beautiful refinement of all was that theory he enunciated about recognizing his son as an heir, but not as a human being. Don’t you see that while it secured the post obit, it also provided some sort of answer to what would soon be the greatest difficulty of
