head of the stairs, at the other end of the dim hall, with Fitzstephan, not far behind, rapidly overtaking her.
He caught her on the between-floors landing, just as I reached the top of the stairs. He pinned one of her arms to her body, but the other, with the gun, was free. He grabbed at it and missed. She twisted the muzzle in to his body as I-with my head bent to miss the edge of the floor-leaped down at them.
I landed on them just in time, crashing into them, smashing them into the corner of the wall, sending her bullet, meant for the sorrel-haired man, into a step.
We weren't standing up. I caught with both hands at the flash of her gun, missed, and had her by the waist. Close to my chin Fitzstephan's lean fingers closed on her gun-hand wrist.
She twisted her body against my right arm. My right arm was still lame from our spill out of the Chrysler. It wouldn't hold. Her thick body went up, turning over on me.
Gunfire roared in my ear, burnt my cheek.
The woman's body went limp.
When O'Gar and Reddy pulled us apart she lay still. The second bullet had gone through her throat.
I went up to the laboratory. Gabrielle Leggett, with the doctor and Collinson kneeling beside her, was lying on the floor.
I told the doctor: "Better take a look at Mrs. Leggett. She's on the stairs. Dead, I think, but you'd better take a look."
The doctor went out. Collinson, chafing the unconscious girl's hands, looked at me as if I were something there ought to be a law against, and said:
"I hope you're satisfied with the way your work got done."
"It got done," I said.
VIII. But and If
Fitzstephan and I ate one of Mrs. Schindler's good dinners that evening in her low-ceilinged basement, and drank her husband's good beer. The novelist in Fitzstephan was busy trying to find what he called Mrs. Leggett's psychological basis.
"The killing of her sister is plain enough, knowing her character as we now do," he said, "and so are the killing of her husband, her attempt to ruin her niece's life when she was exposed, and even her determination to kill herself on the stairs rather than be caught. But the quiet years in between-where do they fit in?"
"It's Leggett's murder that doesn't fit in," I argued. "The rest is all one piece. She wanted him. She killed her sister-or had her killed-in a way to tie him to her; but the law pulled them apart. There was nothing she could do about that, except wait and hope for the chance that always existed, that he would be freed some day. We don't know of anything else she wanted then. Why shouldn't she be quiet, holding Gabrielle as her hostage against the chance she hoped for, living comfortably enough, no doubt, on his money? Wheu she heard of his escape, she came to America and set about finding him. When her detectives located him here she came to him. He was willing to marry her. She had what she wanted. Why should she be anything but quiet? She wasn't a trouble-maker for the fun of it-one of these people who act out of pure mischief. She was simply a woman who wanted what she wanted and was willing to go to any length to get it. Look how patiently, and for how many years, she hid her hatred from the girl. And her wants weren't even very extravagant. You won't find the key to her in any complicated derangements. She was simple as an animal, with an animal's simple ignorance of right and wrong, dislike for being thwarted, and spitefulness when trapped."
Fitzstephan drank beer and asked:
"You'd reduce the Dain curse, then, to a primitive strain in the blood?"
"To less than that, to words in an angry woman's mouth."
"It's fellows like you that take all the color out of life." He sighed behind cigarette smoke. "Doesn't Gabrielle's being made the tool of her mother's murder convince you of the necessity-at least the poetic necessity-of the curse?"
"Not even if she was the tool, and that's something I wouldn't bet on. Apparently Leggett didn't doubt it. He stuffed his letter with those ancient details
