Bagshaw stood looking down at the fallen pot and the mingled fragments at his feet.
"You're quite right," he said to the priest; "there's been a struggle here. And it must have been a struggle between Gwynne and his murderer."
"It seemed to me," said Father Brown modestly, "that something had happened here."
"Yes; it's pretty clear what happened," assented the detective. "The murderer entered by the front door and found Gwynne; probably Gwynne let him in. There was a death grapple, possibly a chance shot, that hit the glass, though they might have broken it with a stray kick or anything. Gwynne managed to free himself and fled into the garden, where he was pursued and shot finally by the pond. I fancy that's the whole story of the crime itself; but, of course, I must look round the other rooms."
The other rooms, however, revealed very little, though Bagshaw pointed significantly to the loaded automatic pistol that he found in a drawer of the library desk.
"Looks as if he was expecting this," he said; "yet it seems queer he didn't take it with him when he went out into the hall."
Eventually they returned to the hall, making their way towards the front door. Father Brown letting his eye rove around in a rather absent-minded fashion. The two corridors, monotonously papered in the same grey and faded pattern, seemed to emphasize the dust and dingy floridity of the few early Victorian ornaments, the green rust that devoured the bronze of the lamp, the dull gold that glimmered in the frame of the broken mirror.
"They say it's bad luck to break a looking-glass," he said. "This looks like the very house of ill-luck. There's something about the very furniture——"
"That's rather odd," said Bagshaw sharply. "I thought the front door would be shut, but it's left on the latch."
There was no reply; and they passed out of the front door into the front garden, a narrower and more formal plot of flowers, having at one end a curiously clipped hedge with a hole in it, like a green cave, under the shadow of which some broken steps peeped out.
