on that wall. Two vases of flowers were up on the mantel. I went for one and could just reach it. I dumped the flowers and ran over to the window. The curtains were gone, but the flames had jumped to the bookcase. When the fire hit shellac, it went wild and spread over the books. I let fly with a vase full of water. Aaron came up with another. We were both breathing hard. I wasnât sure the bookcase was doused, but we were out of vases. Flowers were everywhere.
âWho do you think you are?â came Cuthbertâs voice behind us.
âUntie me at once!â Lysander howled in a higher voice. But he was all tied up and too busy screaming to notice us.
Aaron and I stood there panting. Then we heard foot-steps running down a hall that isnât there now. A big double door began to open. We whirled around, but I was having shooting pains all over like you canât believe. I reached out for Aaron, and his shoulder felt like a Baggie full of bees. We heard buzzing and a voice, but I blacked out for a moment. Hard fluorescent light hit us.
âWhat in the world!â Mrs. Newbery was standing there with her hands on her hips. âI didnât see you two at first. Have you been in this room all along?â
âYep,â Aaron said, lightning-quick.
âWell, cut along home,â Mrs. Newbery said, âand let me lock up. And shut down the computers.â
I was ready to pull their plugs permanently.
We filed out. My head felt like a melon. You can get jet lag from this kind of behavior. We were walking out over the crummy tile floors of the Vanderwhitney part of school. Outside, raw winter weather hit us. There was some snow in the air, and the last buses had gone. We turned toward Fifth Avenue, trudging, silent.
Â
âAnyway, now we know who extinguished the blaze before the hook and ladder company got there,â Aaron said.
âUs,â I said, totally psyched.
âHow you got to go along, Josh, I canât figure at all,â he said. âYou were standing too close or something.â
âAaron, please,â I said. âIâve got a headache the size of Lincoln Center.â
âNo pain, no gain,â he said. âJosh, we both did it. We cellular-reorganized back like seventy-five years. Weâre not talking information superhighway here. Weâre talking a toll-free ten-lane expressway. And weâre on itâin both directions. Talk about interactive.â
I let him rattle on. What choice did I have? He tried to walk out into traffic at the Eighty-sixth Street intersection. Part of me was still back in the Vanderwhitneysâ library all those thousands and thousands of afternoons ago. I thought I could smell smoke in my dress code, under the Bulls warm-up jacket.
âKids.â Aaron shook his head. âIf that was Cuthbertâs idea of playing, thank heaven for Wolfenstein and Sim City 2000. When you get right down to it, thereâs nothing safer and more user-friendly than a video game.â
But I couldnât get my mind away from where weâd been. âIf we hadnât put out that fire, the room would have gone up like a torch. Curtains, rugs, polish on everythingâthat room was totally ...â
âCombustible,â Aaron said.
The whole idea that we saved Cuthbert and Lysander Vanderwhitneyâs lives, especially Lysanderâs, all those years before we were even born was still a hard concept for me. Now Aaron was quiet.
âThereâs more to this process than I thought,â he said after a while.
âMeaning?â
âWell, Iâve made three trips, right? The first time I saw Heather practically wiped out on a horse in traffic. The second time, when I went backward, I saw that girl and that guy doing all that worried kissing. They were like really furtive. This time it was a kid trying to barbecue his brother. Think about it.â
âLike theyâre all
