"Yes," said Father Brown; "and only a convicted thief has ever in this world heard that assurance: 'This night shalt thou be with Me in Paradise.'"

Nobody seemed to know what to do with the silence that followed, until Devine said, abruptly, at last:

"Then how in the world would you explain it all?"

The priest shook his head. "I can't explain it at all, just yet," he said, simply. "I can see one or two odd things, but I don't understand them. As yet I've nothing to go on to prove the man's innocence, except the man. But I'm quite sure I'm right."

He sighed, and put out his hand for his big, black hat. As he removed it he remained gazing at the table with rather a new expression, his round, straight-haired head cocked at a new angle. It was rather as if some curious animal had come out of his hat, as out of the hat of a conjurer. But the others, looking at the table, could see nothing there but the detective's documents and the tawdry old property beard and spectacles.

"Lord bless us," muttered Father Brown, "and he's lying outside dead, in a beard and spectacles." He swung round suddenly upon Devine. "Here's something to follow up, if you want to know. Why did he have two beards?"

With that he bustled in his undignified way out of the room; but Devine was now devoured with curiosity, and pursued him into the front garden.

"I can't tell you now," said Father Brown. "I'm not sure, and I'm bothered about what to do. Come round and see me to-morrow, and I may be able to tell you the whole thing. It may already be settled for me, and—did you hear that noise?"

"A motor-car starting," remarked Devine.

"Mr. John Bankes's motor-car," said the priest. "I believe it goes very fast."
