Silence held them all up again, and then the doctor said rather sulkily: “Well, I may be wrong; there are objections to everything. But I stick to the main point. No man but an idiot would pick up that little hammer if he could use a big hammer.”
With that the lean and quivering hands of Wilfred Bohun went up to his head and seemed to clutch his scanty yellow hair. After an instant they dropped, and he cried: “That was the word I wanted; you have said the word.”
Then he continued, mastering his discomposure: “The words you said were, ‘No man but an idiot would pick up the small hammer.’ ”
“Yes,” said the doctor. “Well?”
“Well,” said the curate, “no man but an idiot did.” The rest stared at him with eyes arrested and riveted, and he went on in a febrile and feminine agitation.
“I am a priest,” he cried unsteadily, “and a priest should be no shedder of blood. I—I mean that he should bring no one to the gallows. And I thank God that I see the criminal clearly now—because he is a criminal who cannot be brought to the gallows.”
“You will not denounce him?” inquired the doctor.
“He would not be hanged if I did denounce him,” answered Wilfred with a wild but curiously happy smile. “When I went into the church 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.”
“No, no,” said Bohun, with a sort of wild fatigue. “It was the lunatic. It was the lunatic.”
The group of the two clerics and the doctor had fallen away from the more official group containing the inspector and the man he had arrested. Now, however, that their own party had broken up, they heard voices from the others. The priest looked up quietly and then looked down again as he heard the blacksmith say in a loud voice:
“I hope I’ve convinced you, Mr. Inspector. I’m a strong man, as you say, but I couldn’t have flung my hammer bang here from Greenford. My hammer hasn’t got wings that it should come flying half a mile over hedges and fields.”
The inspector laughed amicably and said: “No, I think you can be considered out of it, though it’s one of the rummiest coincidences I ever saw. I can only ask you to give us all the assistance you can in finding a man as big and strong as yourself. By George! you might be useful, if only to hold him! I suppose you yourself have no guess at the man?”
“I may have a guess,” said the pale smith, “but it is not at a man.” Then, seeing the scared eyes turn towards his wife on the bench, he put his huge hand on her shoulder and said: “Nor a woman either.”
“What do you mean?” asked the inspector jocularly. “You don’t think cows use hammers, do you?”
“I think no thing of flesh held that hammer,” said the blacksmith in a stifled voice; “mortally speaking, I think the man died alone.”
Wilfred made a sudden forward movement and peered at him with burning eyes.
“Do you mean to say, Barnes,” came the sharp voice of the cobbler, “that the hammer jumped up of itself and knocked the man down?”
“Oh, you gentlemen may stare and snigger,” cried Simeon; “you clergymen who tell us on Sunday in what a stillness the Lord smote Sennacherib. I believe that
