Dull blows came from somewhere. The men must be hunting the roofs and sounding the walls.
Don Luis stretched himself flat on the floor, hid his face in his folded arms and, shutting his eyes, murmured:
"Let's think."
CHAPTER TWELVE
"HELP!"
When Lupin afterward told me this episode of the tragic story, he said, not without a certain self-complacency:
"What astonished me then, and what astonishes me still, as one of the most amazing victories on which I am entitled to pride myself, is that I was able to admit Sauverand and Marie Fauville's innocence on the spot, as a problem solved once and for all. It was a first-class performance, I swear, and surpassed the most famous deductions of the most famous investigators both in psychological value and in detective merit.
"After all, taking everything into account, there was not the shadow of a fresh fact to enable me to alter the verdict. The charges accumulated against the two prisoners were the same, and were so grave that no examining magistrate would have hesitated for a second to commit them for trial, nor any jury to bring them in guilty. I will not speak of Marie Fauville: you had only to think of the marks of her teeth to be absolutely certain. But Gaston Sauverand, the son of Victor Sauverand and consequently the heir of Cosmo Mornington—Gaston Sauverand, the man with the ebony walking-stick and the murderer of Chief Inspector Ancenis—was he not just as guilty as Marie Fauville, incriminated with her by the mysterious letters, incriminated by the very revelation of the husband whom they had killed?
"And yet why did that sudden change take place in me?" he asked. "Why did I go against the evidence? Why did I credit an incredible fact? Why did I admit the inadmissible? Why? Well, no doubt, because truth has an accent that rings in the ears in a manner all its own. On the one side, every proof, every fact, every reality, every certainty; on the other, a story, a story told by one of the three criminals, and therefore, presumptively, absurd and untrue from start to finish. But a story told in a frank voice, a clear, dispassionate, closely woven story, free from complications or improbabilities, a story which supplied no positive solution, but which, by its very honesty, obliged any impartial mind to reconsider the solution arrived at. I believed the story."
The explanation which Lupin gave me was not complete. I asked:
