_Unless she told them!_ Unless she went to them and said: "There is a remorseless slayer loose in the city and some night ... soon now perhaps, very soon ... another woman may be found slain, more horribly slain this time, her throat slashed from ear to ear." It may have been only a solitary crime, brought about by uncontrollable rage. But how can you know, how can you be sure ... when I myself suspected nothing and we were such close, good friends? There is nothing ordinary about a killer, nothing predictable ... even a killer with completely innocent eyes, who can smile and order a cocktail and say: "Heads I pay. Tails we go Dutch." A little whimsical fun, on the part of a dangerous killer. You enter one door and you meet a charming individual, light-hearted, brimming over with a friendly interest in you, your problems, your daily concerns. You enter another door and you meet the same individual, but only for a moment. There's suddenly a tiger close to you, with an odor of death everywhere and long, quivering flanks move in and out, in and out, and, low-crouching, you see death creeping toward you with bared fangs. It seemed to her that her heart had become encased in ice--in a solid block of ice--and was no longer beating. Should she go to the police? Dared she tell, did ... did she really want to send Lathrup's slayer to the electric chair? Supposing it had been a solitary crime, brought on by a wrong so terrible and cruel and heartless that the killer hadn't been a tiger at all? Was there not a killer in everyone, if the provocation was great enough, if all the civilized layers of the human mind were to be stripped away by the inhuman conduct of someone who was bent on destroying you, with no mercy shown, no slightest trace of compassion, no yielding at any point? There, but for the grace of God, go I. Had she not herself been one of Lathrup's victims? Had she not once had an almost uncontrollable desire to make Lathrup suffer as she had suffered, to pay in full measure for the crime which Lathrup had committed in cold blood, with nothing really to gain, for she hadn't wanted Roger to go to bed with her for more than a week or two, if she could have endured him as a lover for even that short length of time. Hadn't she taken Roger away from her, stolen his love just to indulge a cruel whim, just because she happened to be a little bored at the time, and also had a streak of sadism in her nature which made her enjoy inflicting so cruel an injustice upon a woman she had no real reason to dislike? Hadn't that injustice made her want to die, and aroused in her so furious a resentment that she had pictured herself fastening her fingers in Lathrup's throat and forcing her backwards across the desk and pressing and pressing until Lathrup ceased to draw breath?
