this morning I found a madman praying there—that poor Joe, who has been wrong all his life. God knows what he prayed; but with such strange folk it is not incredible to suppose that their prayers are all upside down. Very likely a lunatic would pray before killing a man. When I last saw poor Joe he was with my brother. My brother was mocking him.”
“By Jove!” cried the doctor, “this is talking at last. But how do you explain—”
The Rev. Wilfred was almost trembling with the excitement of his own glimpse of the truth. “Don’t you see; don’t you see,” he cried feverishly; “that is the only theory that covers both the queer things, that answers both the riddles. The two riddles are the little hammer and the big blow. The smith might have struck the big blow, but would not have chosen the little hammer. His wife would have chosen the little hammer, but she could not have struck the big blow. But the madman might have done both. As for the little hammer—why, he was mad and might have picked up anything. And for the big blow, have you never heard, doctor, that a maniac in his paroxysm may have the strength of ten men?”
The doctor drew a deep breath and then said, “By golly, I believe you’ve got it.”
Father Brown had fixed his eyes on the speaker so long and steadily as to prove that his large grey, ox-like eyes were not quite so insignificant as the rest of his face. When silence had fallen he said with marked respect: “ Mr. Bohun, yours is the only theory yet propounded which holds water every way and is essentially unassailable. I think, therefore, that you deserve to be told, on my positive knowledge, that it is not the true one.” And with that the old little man walked away and stared again at the hammer.
“That fellow seems to know more than he ought to,” whispered the doctor peevishly to Wilfred. “Those popish priests are deucedly sly.”
