He hugged his shoulders in, as if to contain a shudder. "Look, Greta," he said, "it's the Snakes who are the warpers and destroyers. We're restoring the past. The Spiders are trying to keep things as first created. We only kill when we must."

I shuddered then, for bursting out of my memory came the glittering, knife-flashing, night-shrouded, bloody image of my lover, the Spider soldier-of-change Erich von Hohenwald, dying in the grip of a giant silver spider, or spider-shaped entity large as he, as they rolled in a tangled ball down a flight of rocks in Central Park.

But the memory-burst didn't blow up my mind, as it had done a year ago, no more than snapping the black thread from my sweater had ended the world. I asked Martin, "Is that what the Snakes say?"

"Of course not! They make the same claims we do. But somewhere, Greta, you have to trust." He put out the middle finger of his hand.

I didn't take hold of it. He whirled it away, snapping it against his thumb.

"You're still grieving for that carrion there!" he accused me. He jerked down a section of white curtain and whirled it over the stiffening body. "If you must grieve, grieve for Miss Nefer! Exiled, imprisoned, locked forever in the past, her mind pulsing faintly in the black hole of the dead and gone, yearning for Nirvana yet nursing one lone painful patch of consciousness. And only to hold a fort! Only to make sure Mary Stuart is executed, the Armada licked, and that all the other consequences flow on. The Snakes' Elizabeth let Mary live ... and England die ... and the Spaniard hold North America to the Great Lakes and New Scandinavia."

Once more he put out his middle finger.

"All right, all right," I said, barely touching it. "You've convinced me."

"Great!" he said. "'By for now, Greta. I got to help strike the set."

"That's good," I said. He loped out.
