Reaching Paris at nine o’clock in the evening, not by the Lyons road as he had said, but by the Orleans train, M. Verduret hurried up to the Archangel, where he found the cashier impatiently expecting him.

“You are about to hear some rich developments,” he said to Prosper, “and see how far back into the past one has to seek for the primary cause of a crime. All things are linked together and dependent upon each other in this world of ours. If Gaston de Clameran had not entered a little cafe at Tarascon to play a game of billiards twenty years ago, your money-safe would not have been robbed three weeks ago.

“Valentine de la Verberie is punished in 1866 for the murder committed for her sake in 1840. Nothing is neglected or forgotten, when stern Retribution asserts her sway. Listen.”

And he forthwith related all that he had discovered, referring, as he went along, to a voluminous manuscript which he had prepared, with many notes and authenticated proofs attached.

During the last week M. Verduret had not had twenty-four hours’ rest, but he bore no traces of fatigue. His iron muscles braved any amount of labor, and his elastic nature was too well tempered to give way beneath such pressure.

While any other man would have sunk exhausted in a chair, he stood up and described, with the enthusiasm and captivating animation peculiar to him, the minutest details and intricacies of the plot that he had devoted his whole energy to unravelling; personating every character he brought upon the scene to take part in the strange drama, so that his listener was bewildered and dazzled by his brilliant acting.

As Prosper listened to this narrative of events happening twenty years back, the secret conversations as minutely related as if overheard the moment they took place, it sounded more like a romance than a statement of plain facts.

All these ingenious explanations might be logical, but what foundation did they possess? Might they not be the dreams of an excited imagination?

M. Verduret did not finish his report until four o’clock in the morning; then he cried, with an accent of triumph:

“And now they are on their guard, and sharp, wary rascals too: but they won’t escape me; I have cornered them beautifully. Before a week is over, Prosper, you will be publicly exonerated, and will come out of this scrape with flying colors. I have promised your father you shall.”
