"You are right. It is my duty to tell everything, whatever comes of it."

"Nothing will come of it, I pledge my word, on condition that you save Hortense Daniel. A moment's hesitation may undo us all. Speak. No details, but the actual facts."

"Madame de Lourtier is not my wife. The only woman who has the right to bear my name is one whom I married when I was a young colonial official. She was a rather eccentric woman, of feeble mentality and incredibly subject to impulses that amounted to monomania. We had two children, twins, whom she worshipped and in whose company she would no doubt have recovered her mental balance and moral health, when, by a stupid accident--a passing carriage--they were killed before her eyes. The poor thing went mad ... with the silent, secretive madness which you imagined. Some time afterwards, when I was appointed to an Algerian station, I brought her to France and put her in the charge of a worthy creature who had nursed me and brought me up. Two years later, I made the acquaintance of the woman who was to become the joy of my life. You saw her just now. She is the mother of my children and she passes as my wife. Are we to sacrifice her? Is our whole existence to be shipwrecked in horror and must our name be coupled with this tragedy of madness and blood?"

Rénine thought for a moment and asked:

"What is the other one's name?"

"Hermance."

"Hermance! Still that initial ... still those eight letters!"

"That was what made me realize everything just now," said M. de Lourtier. "When you compared the different names, I at once reflected that my unhappy wife was called Hermance and that she was mad ... and all the proofs leapt to my mind."

"But, though we understand the selection of the victims, how are we to explain the murders? What are the symptoms of her madness? Does she suffer at all?"

"She does not suffer very much at present. But she has suffered in the past, the most terrible suffering that you can imagine: since the moment when her two children were run over before her eyes, night and day she had the horrible spectacle of their death before her eyes, without a moment's interruption, for she never slept for a single second. Think of the torture of it! To see her children dying through all the hours of the long day and all the hours of the interminable night!"
