I threw myself forward, toward the breathless child, and as I did the rest of the infants burst into terrified wails. I reached the child and smacked her little upturned baby butt. She blinked her eyes open in sudden shock, drew in a breath, and joined the rest of her nursery mates in crying.

"No," Agatha screamed, "no, no, no! He'll hear you! He'll hear you!" The stump of her left arm flashed out toward me, and I felt the impact both against my body and against my soul, as though she had driven a chip of ice deep into my chest. The power of the blow flung me back against a wall like a toy, hard enough to send my staff and rod clattering to the floor. By some miracle or other, I kept hold of my sack of ghost dust, but my head vibrated like a hammer-struck bell, and cold shivers wracked my body in rapid succession.

"Michael," I wheezed, as loudly as I could, but already I could hear doors being thrown open, heavy work boots pounding toward me. I struggled to my feet and shook my head to clear it. The wind rose to gale force, sending cribs skittering around the room on their little wheels, tearing at my eyes so that I had to shield them with one hand. Dammit. The dust would be useless in such a gale.

"Hush little baby, hush little baby, hush little baby." Agatha's ghost bowed over the infant girl's cradle again, and thrust the stump of her left arm down and into the mouth of the child, her translucent flesh passing seamlessly into the infant's skin. The child jerked and stopped breathing, though she still attempted to cry.

I shouted a wordless challenge and charged the spirit. If I could not cast the dust upon her from across the room, I could thrust the leather bag into her ghostly flesh and pin her into place from within-agonizing, but undoubtedly effective.

Agatha's head whipped toward me as I came, and she jerked away from the child with a snarl. Her hair had come free in the gale and spread about her face in a ferocious mane well suited to the feral features that had replaced her gentle expression. She drew back her left hand, and there suddenly appeared, floating just above the stump, a short, heavy-headed hatchet. She shrieked and brought the hatched down at me.

Ghostly steel chimed on true iron, and Amoracchius's light flared bright-white. Michael slid his feet into position on the floor, gritting his teeth with effort, and kept the spirit-weapon from touching my flesh.

" Dresden ," he called. "The dust!"

I fought my way forward, through the wind, shoved my fist into Agatha's weapon-arm, and shook loose some of the ghost dust from the leather sack.
