Part 60

"In the first place, because it did not strike me that Mlle. Darcieux felt any very great affection for her father."

"Never mind! Think of it: a father who tries to kill his daughter! A father who, for months on end, repeats his monstrous attempt four, five, six times over again!... Well, isn't that enough to blight a less sensitive soul than Jeanne's for good and all? What a hateful memory!"

"She will forget."

"One does not forget such a thing as that."

"She will forget, doctor, and for a very simple reason...."

"Explain yourself!"

"She is not M. Darcieux's daughter!"

"Eh?"

"I repeat, she is not that villain's daughter."

"What do you mean? M. Darcieux...."

"M. Darcieux is only her step-father. She had just been born when her father, her real father, died. Jeanne's mother then married a cousin of her husband's, a man bearing the same name, and she died within a year of her second wedding. She left Jeanne in M. Darcieux's charge. He first took her abroad and then bought this country-house; and, as nobody knew him in the neighbourhood, he represented the child as being his daughter. She herself did not know the truth about her birth."

The doctor sat confounded. He asked:

"Are you sure of your facts?"

"I spent my day in the town-halls of the Paris municipalities. I searched the registers, I interviewed two solicitors, I have seen all the documents. There is no doubt possible."

"But that does not explain the crime, or rather the series of crimes."

"Yes, it does," declared Lupin. "And, from the start, from the first hour when I meddled in this business, some words which Mlle. Darcieux used made me suspect that direction which my investigations must take. 'I was not quite five years old when my mother died,' she said. 'That was sixteen years ago.' Mlle. Darcieux, therefore, was nearly twenty-one, that is to say, she was on the verge of attaining her majority. I at once saw that this was an important detail. The day on which you reach your majority is the day on which your accounts are rendered. What was the financial position of Mlle. Darcieux, who was her mother's natural heiress? Of course, I did not think of the father for a second. To begin with, one can't imagine a thing like that; and then the farce which M. Darcieux was playing ... helpless, bedridden, ill...."

"Really ill," interrupted the doctor.

"All this diverted suspicion from him ... the more so as I believe that he himself was exposed to criminal attacks. But was there not in the family some person who would be interested in their removal? My journey to Paris revealed the truth to me: Mlle. Darcieux inherits a large fortune from her mother, of which her step-father draws the income. The solicitor was to have called a meeting of the family in Paris next month. The truth would have been out. It meant ruin to M. Darcieux."

"Then he had put no money by?"

"Yes, but he had lost a great deal as the result of unfortunate speculations."

"But, after all, Jeanne would not have taken the management of her fortune out of his hands!"

"There is one detail which you do not know, doctor, and which I learnt from reading the torn letter. Mlle. Darcieux is in love with the brother of Marceline, her Versailles friend; M. Darcieux was opposed to the marriage; and--you now see the reason--she was waiting until she came of age to be married."

"You're right," said the doctor, "you're right.... It meant his ruin."

"His absolute ruin. One chance of saving himself remained, the death of his step-daughter, of whom he is the next heir."

"Certainly, but on condition that no one suspected him."

"Of course; and that is why he contrived the series of accidents, so that the death might appear to be due to misadventure. And that is why I, on my side, wishing to bring things to a head, asked you to tell him of Mlle. Darcieux's impending departure. From that moment, it was no longer enough for the would-be sick man to wander about the grounds and the passages, in the dark, and execute some leisurely thought-out plan. No, he had to act, to act at once, without preparation, violently, dagger in hand. I had no doubt that he would decide to do it. And he did."

"Then he had no suspicions?"

"Of me, yes. He felt that I would return to-night, and he kept a watch at the place where I had already climbed the wall."
