must get all the pieces first, and then sit down and laboriously fit them up."
He looked down into his cup, his face in repose and reflective.
"Ah, sir," he went on, "if one could be certain that one had always every piece, there would no longer remain such a thing as a human mystery. Every event dovetails into every other event that precedes and follows. With the pieces complete, the truth could never elude us. But, alas, sir, human intelligence is feeble and easily deludes itself, and the relations and ramifications of events are vast and intricate."
"Then, sir," said Mr. Esdale Moore, "you do not believe that the criminal can create a series of false evidences that will be at all points consistent with the truth."
"No man can do it," replied Abner. "For to do that, one must know everything that goes before and everything that follows the event which one is attempting to falsify. And this omniscience only the intelligence of God can compass. It is impossible for the human mind to manufacture a false consistency of events except to a very limited extent."
"Then, gentlemen," cried the lawyer, "you can make me no excuse for leaving this affair a mystery."
"Yes," replied my uncle, "we could make you an excuse—a valid and sound excuse: the excuse of incompetency."
