Her voice choked silent. Her face froze-as if some inner reflex held her expression immobile so we couldn't guess what was going through her mind. An instant later, she whirled to face the three of us at the window. "This Sebastian was a powerful psychic?"

We all nodded.

"What was his power?"

Impervia and the Caryatid looked at me to answer. I chose my words carefully. "Our psionics teacher says Sebastian can talk to the world: as if land, sea, and air are full of happy puppies, eager to fulfill the boy's tiniest wish. So his powers cover the whole spectrum."

"The boy talks directly to nanites? And he's headed for Niagara Falls?" Dreamsinger's voice had gone shrill. "With a creature that can make itself look like Rosalind?"

Mother Tzekich stirred at her daughter's name, but didn't have a chance to speak. Dreamsinger surged toward the window where Impervia, the Caryatid, and I still crouched. The Spark Lord grabbed me by the jacket and heaved me up as if I weighed no more than a rag doll. "Fool!" she whispered, so softly no one else could hear. "Those curds weren't a bioweapon. They were cast-off cellules from a Lucifer."

"But I thought…" Opal had said the flake-away bits of Lucifer were like grains of black gunpowder. Dark and dry. I suddenly remembered that both Dreamsinger and her brother had asked if I was sure the curds I'd seen were white and wet, not dark and dry. They both must have suspected there was a Lucifer in our neighborhood, but my talk of a bioweapon had made it seem like something else. "It looked like cottage cheese," I said. "Honestly…"

"The Lucifer mutated," Dreamsinger told me in another furious whisper. "It's been trying to do that for decades. It knows Spark Royal can track its life-signs… so the blasted thing finally managed to change its metabolism. And now it's going to Niagara Falls with a psychic?"

She tossed me aside in disgust. Pure luck let me grab a corner of the window frame and catch my balance; otherwise, I would have fallen onto the broken glass that littered the floor. Dreamsinger didn't care-she was already stepping over the sill, out onto the dark lawn. At the same time, she tapped her pearl necklace: the one that was actually a radio transmitter. "Spark Royal, attend," she snapped. "I need immediate pick-up, this location."

"Please activate anchor," a metallic voice said from the necklace.

"Give me ten seconds."

Dreamsinger reached toward her waist. To my eyes, she was grabbing at nothingness a short distance in front of her bare navel. A belt pack, I thought; her armor must have pouches and attachments that I couldn't see because of the Chameleon spell. A moment later, she pulled a small device from thin air-a black plastic box the size of a book, with four metallic gold horseshoes arranged in a diamond on its top face.

"Dearest sister," she called to the Caryatid, "could you come here, please?"

The Caryatid hurried forward.

"Do you see this switch?" Dreamsinger pointed to a toggle on the box's side. "When I'm gone, please push that; it turns the anchor off. Be careful not to turn it on again-just keep the anchor safe, and I'll come for it someday."

"Yes, milady."

"Good. Keep faith with me." Dreamsinger kissed the Caryatid lightly on the lips. Then she whirled and told the rest of us, "Only my sister on the Burdensome Path may touch the device. Everyone else stand clear."

Without waiting for an answer, she stepped away from the Caryatid, pushed the toggle-switch herself, and laid the box on the ground. "Spark Royal, attend," she said to empty air. "The anchor is active. Take me home."

A tube of creamy white lashed down from the sky: the same ectoplasmic smoke we'd seen at Death Hotel. It glinted with color, buffed gold, sea green, peacock blue… and again I tried to imagine what it might be. An energy beam projected from an orbiting satellite? Ionized particles like the Aurora Borealis, curled in a shimmering sleeve? Or perhaps a living creature, some ethereal worm hundreds of kilometers long, ready to lower its tail whenever a Spark commanded?

The thing stabbed down like a lightning bolt, straight for Dreamsinger's anchor. The device must have worked like a magnet, for the instant the smoke-tail made contact, its tip adhered to the box; then the tail's mouth spread wider, until its edges touched all four golden horseshoes on the anchor's top surface.

The tip was locked down and secure. But the rest of the smoke-tail flapped wildly, making no sound but whipping through the darkness in ghostly frenzy. A fluttering wraith reaching high out of sight.

Beyond the house, dogs began to bark-Xavier's guard pack, finally noticing something was amiss. Why hadn't they come running when Dreamsinger made the windows explode? Idiotic beasts. Then I realized the explosion had taken place inside the antiscrying shield; since the dogs were outside, the antiscrying sorcery would make them ignore the din of smashing glass. They wouldn't react till something became visible on their side of the shield.

Something like a big smoky tube sprouting from the lawn to the stratosphere.

Three German Shepherds dashed snarling into view; then they stopped in a doggy double-take. They paid no attention to those of us still within the antiscrying shield: all they saw was a pillar of ghost-smoke flicking around the yard, sweeping past the bare-branched trees, occasionally billowing out over the bluffs before whisking back to the house again. The tube's random swooping soon took it in the dogs' direction… and they backed off, whining in their throats. The smoke didn't touch them-it didn't touch anything, not the house, not the trees, not a single blade of winter-parched grass-but it came within a hair of grazing everything in sight, skimming past my face, darting at the Caryatid's feet, even looping once around Impervia's neck before uncoiling again and careening off. As if it were stalking each of us in turn, trying to make us flinch.

Flinch we did… and the smoke-tail wagged itself happily, heading off to scare the dogs again.

The metallic voice spoke from Dreamsinger's necklace. "Anchor established. Ready for transport to Spark Royal."

"Dear sister, I must go," Dreamsinger told the Caryatid. "Turn off the switch when I'm gone."

The Caryatid nodded. Dreamsinger smiled back, then squatted beside the anchor box. She slid one finger under the tethered end of the smoke-tail, slipping her fingertip into the mouth of the tube… and suddenly her whole body was sucked inside, her bones, her flesh turning as malleable as clay. It looked like something from a comic drawing, a woman's body pulled thin as a garter snake, then rammed into an aperture no bigger than a mouse hole; but there was no humor in seeing such grisly distortion for real. The whole thing lasted less than a second, and made no sound except a soft swish of air-otherwise, I might have been sick on the spot.

The Caryatid, looking equally queasy, forced herself to press the anchor's toggle-switch. Click. Immediately, the smoke-tail slipped free, jerking loose from its tether and bounding high into the sky like a taut rope suddenly cut. It soared halfway to the clouds, dropped down once more to the treetops, then flew straight up out of sight.

Mission accomplished. The tube had removed Dreamsinger to Spark Royal-whence, presumably, she'd ride a similar tube to Niagara Falls. There'd have to be an anchor device somewhere in the Niagara area, ready to catch hold of the tube's tail end… but I suspected there were anchors all over the world, planted in out-of-the-way corners, waiting for the day a Spark Lord needed to get somewhere in a hurry.

There'd been one in Death Hotel-a place the small device could lie undisturbed for centuries. It was probably radio-controlled, ready to activate itself when a signal came…
