Jean Louis took umbrage at this:

"I must ask you to believe, monsieur, that I have not said a word which is not the exact truth."

"I expressed myself badly," said Renine, with great kindliness. "Certainly you have not said a word that does not agree with what you believe to be the exact truth. But the truth is not, cannot be what you believe it to be."

The young man folded his arms:

"In any case, monsieur, it seems likely that I should know the truth better than you do."

"Why better? What happened on that tragic night can obviously be known to you only at secondhand. You have no proofs. Neither have Madame d'Imbleval and Madame Vaurois."

"No proofs of what?" exclaimed Jean Louis, losing patience.

"No proofs of the confusion that took place."

"What! Why, it's an absolute certainty! The two children were laid in the same cradle, with no marks to distinguish one from the other; and the nurse was unable to tell...."

"At least, that's her version of it," interrupted Renine.

"What's that? Her version? But you're accusing the woman."

"I'm accusing her of nothing."

"Yes, you are: you're accusing her of lying. And why should she lie? She had no interest in doing so; and her tears and despair are so much evidence of her good faith. For, after all, the two mothers were there ... they saw the woman weeping ... they questioned her.... And then, I repeat, what interest had she ...?"

Jean Louis was greatly excited. Close beside him, Madame d'Imbleval and Madame Vaurois, who had no doubt been listening behind the doors and who had stealthily entered the room, stood stammering, in amazement:

"No, no ... it's impossible.... We've questioned her over and over again.

Why should she tell a lie?..."

"Speak, monsieur, speak," Jean Louis enjoined. "Explain yourself. Give your reasons for trying to cast doubt upon an absolute truth!"

"Because that truth is inadmissible," declared Renine, raising his voice and growing excited in turn to the point of punctuating his remarks by thumping the table. "No, things don't happen like that. No, fate does not display those refinements of cruelty and chance is not added to chance with such reckless extravagance! It was already an unprecedented chance that, on the very night on which the doctor, his man-servant and his maid were out of the house, the two ladies should be seized with labour-pains at the same hour and should bring two sons into the world at the same time. Don't let us add a still more exceptional event! Enough of the uncanny! Enough of lamps that go out and candles that refuse to burn! No and again no, it is not admissable that a midwife should become confused in the essential details of her trade. However bewildered she may be by the unforeseen nature of the circ.u.mstances, a remnant of instinct is still on the alert, so that there is a place prepared for each child and each is kept distinct from the other. The first child is here, the second is there. Even if they are lying side by side, one is on the left and the other on the right.

Even if they are wrapped in the same kind of binders, some little detail differs, a trifle which is recorded by the memory and which is inevitably recalled to the mind without any need of reflection. Confusion? I refuse to believe in it. Impossible to tell one from the other? It isn't true. In the world of fiction, yes, one can imagine all sorts of fantastic accidents and heap contradiction on contradiction. But, in the world of reality, at the very heart of reality, there is always a fixed point, a solid nucleus, about which the facts group themselves in accordance with a logical order.

I therefore declare most positively that Nurse Boussignol could not have mixed up the two children."

All this he said decisively, as though he had been present during the night in question; and so great was his power of persuasion that from the very first he shook the certainty of those who for more than a quarter of a century had never doubted.

The two women and their son pressed round him and questioned him with breathless anxiety:

"Then you think that she may know ... that she may be able to tell us....?"

He corrected himself:

"I don't say yes and I don't say no. All I say is that there was something in her behaviour during those hours that does not tally with her statements and with reality. All the vast and intolerable mystery that has weighed down upon you three arises not from a momentary lack of attention but from something of which we do not know, but of which she does. That is what I maintain; and that is what happened."

Jean Louis said, in a husky voice:

"She is alive.... She lives at Carhaix.... We can send for her...."

Hortense at once proposed:

"Would you like me to go for her? I will take the motor and bring her back with me. Where does she live?"

"In the middle of the town, at a little draper's shop. The chauffeur will show you. Mlle. Boussignol: everybody knows her...."

"And, whatever you do," added Renine, "don't warn her in any way. If she's uneasy, so much the better. But don't let her know what we want with her."

Twenty minutes pa.s.sed in absolute silence. Renine paced the room, in which the fine old furniture, the handsome tapestries, the well-bound books and pretty knick-knacks denoted a love of art and a seeking after style in Jean Louis. This room was really his. In the adjoining apartments on either side, through the open doors, Renine was able to note the bad taste of the two mothers.

He went up to Jean Louis and, in a low voice, asked:

"Are they well off?"

"Yes."

"And you?"

"They settled the manor-house upon me, with all the land around it, which makes me quite independent."

"Have they any relations?"

"Sisters, both of them."

"With whom they could go to live?"

"Yes; and they have sometimes thought of doing so. But there can't be any question of that. Once more, I a.s.sure you...."

Meantime the car had returned. The two women jumped up hurriedly, ready to speak.

"Leave it to me," said Renine, "and don't be surprised by anything that I say. It's not a matter of asking her questions but of frightening her, of flurrying her.... The sudden attack," he added between his teeth.

The car drove round the lawn and drew up outside the windows. Hortense sprang out and helped an old woman to alight, dressed in a fluted linen cap, a black velvet bodice and a heavy gathered skirt.

The old woman entered in a great state of alarm. She had a pointed face, like a weasel's, with a prominent mouth full of protruding teeth.

"What's the matter, Madame d'Imbleval?" she asked, timidly stepping into the room from which the doctor had once driven her. "Good day to you, Madame Vaurois."

The ladies did not reply. Renine came forward and said, sternly:

"Mlle. Boussignol, I have been sent by the Paris police to throw light upon a tragedy which took place here twenty-seven years ago. I have just secured evidence that you have distorted the truth and that, as the result of your false declarations, the birth-certificate of one of the children born in the course of that night is inaccurate. Now false declarations in matters of birth-certificates are misdemeanours punishable by law. I shall therefore be obliged to take you to Paris to be interrogated ... unless you are prepared here and now to confess everything that might repair the consequences of your offence."

The old maid was shaking in every limb. Her teeth were chattering. She was evidently incapable of opposing the least resistance to Renine.

"Are you ready to confess everything?" he asked.

"Yes," she panted.

"Without delay? I have to catch a train. The business must be settled immediately. If you show the least hesitation, I take you with me. Have you made up your mind to speak?"
