I entered the room, and Agatha Hagglethorn's voice rolled over me like a drug, making me blink and shudder. I had to keep focused, my thoughts on the cool power of my magic flowing through my pentacle and coming out in its spectral light.

If that diamond ring don't shine …

I licked my lips and watched the ghost as it stooped over one of the rolling cradles. She smiled, loving-kindness in her eyes, and breathed out her song over the baby.

The infant shuddered out a tiny breath, eyes closed in sleep, and did not inhale.

Hush little baby…

Time had run out. In a perfect world, I would have simply dumped the dust onto the ghost. But it's not a perfect world: Ghosts don't have to play by the rules of reality, and until they acknowledge that you're there, it's tough, very, very tough, to affect them at all. Confrontation is the only way, and even then, knowing the shade's identity and speaking its name aloud is the only sure way to make it face you. And, better and better, most spirits can't hear just anyone-it takes magic to make a direct call to the hereafter.

I rose fully to my feet, bag gripped in my hand and shouted, forcing my will into my voice, "Agatha Hagglethorn!"

The spirit started, as though a distant voice had come to her, and turned toward me. Her eyes widened. The song abruptly fell silent.

"Who are you?" she said. "What are you doing in my nursery?"

I struggled to keep the details Bob had told me about the ghost straight. "This isn't your nursery, Agatha Hagglethorn. It's more than a hundred years since you died. You aren't real. You are a ghost, and you are dead."

The spirit drew itself up with a sort of cold, high-society haughtiness. "I might have known. Benson sent you, didn't he? Benson is always doing something cruel and petty like this, then calling me a madwoman. A madwoman! He wants to take my child away."

"Benson Hagglethorn is long dead, Agatha Hagglethorn," I responded, and gathered back my right hand to throw. "As is your child. As are you. These little ones are not yours to sing to or bear away." I steeled myself to throw, began to bring my arm forward.

The spirit looked at me with an expression of lost, lonely confusion. This was the hard part about dealing with really substantial, dangerous ghosts. They were almost human. They appeared to be able to feel emotion, to have some degree of self-awareness. Ghosts aren't alive, not really-they're a footprint in stone, a fossilized skeleton. They are shaped like the original, but they aren't it.
