"On such a day, I killed so-and-so; on such a day so-and-so!"
And the sum total was six dead bodies.
Against all expectation, the experts in handwriting had no difficulty in agreeing and unanimously declared that the writing was "that of a woman, an educated woman, possessing artistic tastes, imagination and an extremely sensitive nature." The "lady with the hatchet," as the journalists christened her, was decidedly no ordinary person; and scores of newspaper-articles made a special study of her case, exposing her mental condition and losing themselves in far-fetched explanations.
Nevertheless it was the writer of one of these articles, a young journalist whose chance discovery made him the centre of public attention, who supplied the one element of truth and shed upon the darkness the only ray of light that was to penetrate it. In casting about for the meaning of the figures which followed the six names, he had come to ask himself whether those figures did not simply represent the number of the days separating one crime from the next. All that he had to do was to check the dates. He at once found that his theory was correct. Mlle. Vernisset had been carried off one hundred and thirty-two days after Madame Ladoue; Mlle. Covereau one hundred and eighteen days after Honorine Vernisset; and so on.
There was therefore no room for doubt; and the police had no choice but to accept a solution which so precisely fitted the circumstances: the figures corresponded with the intervals. There was no mistake in the records of the lady with the hatchet.
But then one deduction became inevitable. Miss Williamson, the latest victim, had been carried off on the 26th of June last, and her name was followed by the figures 114: was it not to be presumed that a fresh crime would be committed a hundred and fourteen days later, that is to say, on the 18th of October? Was it not probable that the horrible business would be repeated in accordance with the murderer's secret intentions? Were they not bound to pursue to its logical conclusion the argument which ascribed to the figures--to all the figures, to the last as well as to the others--their value as eventual dates?
Now it was precisely this deduction which was drawn and was being weighed and discussed during the few days that preceded the 18th of October, when logic demanded the performance of yet another act of the abominable tragedy. And it was only natural that, on the morning of that day, Prince Rénine and Hortense, when making an appointment by telephone for the evening, should allude to the newspaper-articles which they had both been reading:
"Look out!" said Rénine, laughing. "If you meet the lady with the hatchet, take the other side of the road!"
"And, if the good lady carries me off, what am I to do?"
"Strew your path with little white pebbles and say, until the very moment when the hatchet flashes in the air, 'I have nothing to fear; he will save me.' He is myself ... and I kiss your hands. Till this evening, my dear."
