第15章 The Secret Garden(7)

There's that old buffer you found on the lawn," and he pointed without pretence of reverence at the big black body with the yellow head. "We've found out who he is, anyhow.""Indeed!" cried the astonished doctor, "and who is he?""His name was Arnold Becker," said the under-detective, "though he went by many aliases. He was a wandering sort of scamp, and is known to have been in America; so that was where Brayne got his knife into him. We didn't have much to do with him ourselves, for he worked mostly in Germany. We've communicated, of course, with the German police. But, oddly enough, there was a twin brother of his, named Louis Becker, whom we had a great deal to do with. In fact, we found it necessary to guillotine him only yesterday. Well, it's a rum thing, gentlemen, but when I saw that fellow flat on the lawn I had the greatest jump of my life. If Ihadn't seen Louis Becker guillotined with my own eyes, I'd have sworn it was Louis Becker lying there in the grass. Then, of course, I remembered his twin brother in Germany, and following up the clue--"The explanatory Ivan stopped, for the excellent reason that nobody was listening to him. The Commandant and the doctor were both staring at Father Brown, who had sprung stiffly to his feet, and was holding his temples tight like a man in sudden and violent pain.

"Stop, stop, stop!" he cried; "stop talking a minute, for Isee half. Will God give me strength? Will my brain make the one jump and see all? Heaven help me! I used to be fairly good at thinking. I could paraphrase any page in Aquinas once. Will my head split--or will it see? I see half--I only see half."He buried his head in his hands, and stood in a sort of rigid torture of thought or prayer, while the other three could only go on staring at this last prodigy of their wild twelve hours.

When Father Brown's hands fell they showed a face quite fresh and serious, like a child's. He heaved a huge sigh, and said:

"Let us get this said and done with as quickly as possible. Look here, this will be the quickest way to convince you all of the truth." He turned to the doctor. "Dr. Simon," he said, "you have a strong head-piece, and I heard you this morning asking the five hardest questions about this business. Well, if you will ask them again, I will answer them."Simon's pince-nez dropped from his nose in his doubt and wonder, but he answered at once. "Well, the first question, you know, is why a man should kill another with a clumsy sabre at all when a man can kill with a bodkin?""A man cannot behead with a bodkin," said Brown calmly, "and for this murder beheading was absolutely necessary.""Why?" asked O'Brien, with interest.

"And the next question?" asked Father Brown.

"Well, why didn't the man cry out or anything?" asked the doctor; "sabres in gardens are certainly unusual.""Twigs," said the priest gloomily, and turned to the window which looked on the scene of death. "No one saw the point of the twigs. Why should they lie on that lawn (look at it) so far from any tree? They were not snapped off; they were chopped off. The murderer occupied his enemy with some tricks with the sabre, showing how he could cut a branch in mid-air, or what-not. Then, while his enemy bent down to see the result, a silent slash, and the head fell.""Well," said the doctor slowly, "that seems plausible enough.

But my next two questions will stump anyone."The priest still stood looking critically out of the window and waited.

"You know how all the garden was sealed up like an air-tight chamber," went on the doctor. "Well, how did the strange man get into the garden?"Without turning round, the little priest answered: "There never was any strange man in the garden."There was a silence, and then a sudden cackle of almost childish laughter relieved the strain. The absurdity of Brown's remark moved Ivan to open taunts.

"Oh!" he cried; "then we didn't lug a great fat corpse on to a sofa last night? He hadn't got into the garden, I suppose?""Got into the garden?" repeated Brown reflectively. "No, not entirely.""Hang it all," cried Simon, "a man gets into a garden, or he doesn't.""Not necessarily," said the priest, with a faint smile. "What is the nest question, doctor?""I fancy you're ill," exclaimed Dr. Simon sharply; "but I'll ask the next question if you like. How did Brayne get out of the garden?""He didn't get out of the garden," said the priest, still looking out of the window.

"Didn't get out of the garden?" exploded Simon.

"Not completely," said Father Brown.

Simon shook his fists in a frenzy of French logic. "A man gets out of a garden, or he doesn't," he cried.

"Not always," said Father Brown.
