"What the devil do you mean?" demanded Bagshaw. "Gwynne was lying dead with his head in the pond."
"Oh, yes," said Father Brown.
After a moment he went on: "Let's go back to that theory of yours, which was a very good one, though I don't quite agree with it. You suppose the murderer came in at the front door, met the Judge in the front hall, struggling with him and breaking the mirror; that the judge then retreated into the garden, where he was finally shot. Somehow, it doesn't sound natural to me. Granted he retreated down the hall, there are two exits at the end, one into the garden and one into the house. Surely, he would be more likely to retreat into the house? His gun was there; his telephone was there; his servant, so far as he knew, was there. Even the nearest neighbours were in that direction. Why should he stop to open the garden door and go out alone on the deserted side of the house?"
"But we know he did go out of the house," replied his companion, puzzled. "We know he went out of the house, because he was found in the garden."
"He never went out of the house, because he never was in the house," said Father Brown. "Not that evening, I mean. He was sitting in that bungalow. I read that lesson in the dark, at the beginning, in red and golden stars across the garden. They were worked from the hut; they wouldn't have been burning at all if he hadn't been in the hut. He was trying to run across to the house and the telephone, when the murderer shot him beside the pond."
"But what about the pot and the palm and the broken mirror?" cried Bagshaw. "Why, it was you who found them! It was you yourself who said there must have been a struggle in the hall."
The priest blinked rather painfully. "Did I?" he muttered. "Surely, I didn't say that. I never thought that. What I think I said, was that something had happened in the hall. And something did happen; but it wasn't a struggle."
"Then what broke the mirror?" asked Bagshaw shortly.
"A bullet broke the mirror," answered Father Brown gravely; "a bullet fired by the criminal. The big fragments of falling glass were quite enough to knock over the pot and the palm."
"Well, what else could he have been firing at except Gwynne?" asked the detective.
