sitting on a stool moving plastic tubes around. A guy I hadnât seen before was standing at the desk where Jaya had been. He had reddish-blond hair, shallow eyes, and a tiny mouth that made him look like an angry doll.
âMay I help you?â he asked.
Make that reddish-blond hair and an English accent.
âYeah, I wanted to know . . . um . . . whereâs Jaya Rao?â I asked.
âDownstairs on Stack 5. Why?â He didnât sound too friendly.
âNothing, really, itâs just . . . she put some objects on reserve for me.â
âI can get those for you. Last name?â
âNovikov.â
âBe right back.â He pushed a wooden cart over to the reserve shelves, loaded it with my robots, and started pushing it back to the window.
âThanks,â I said. âSo how do I get to Stack 5?â
âYou donât. The public isnât allowed in the stacks.â
âOh well. I just wanted to say hi to Jaya.â
The guy shrugged unhelpfully, but the girl said, âAre you a friend of hers? I can send down a message if you like.â
âCool. Just tell her Leo says hi,â I said. Would she even remember me?
âHere, why donât you write her a note?â The girl handed me a blank call slip and one of the stubby little pencils.
âOkay, thanks.â What to write? I bit the end of the pencil.
âAbigail, the pneums are piling up,â said the English guy. He sounded like we were wasting his valuable time.
âAll right,â said the girlâAbigail. âJust give it to me when youâre finished,â she told me.
I took the robots over to one of the library tables, where I stared at the blank slip for a while. Finally I wrote
Schist, youâre not here! Iâm upstairs in the Main Exam Room. I just wanted to say hi. Leo N. (The guy with the robots.)
I folded it over, wrote
Jaya Rao
on the flap, and went back to the desk.
âYes?â said the guy.
âMy note,â I explained, waving it at Abigail, who came over and took it. I watched her tuck the message into a plastic can and stuff the can into one of the pipes.
âWhat are those things?â I asked the guy.
âWhat things?â
âThose plastic cans that Abigail put my note in.â
âYouâve never seen pneumatic tubes?â His voice dripped with disdain, like Iâd never heard of an airplane.
âObviously not,â I said. âWhat are they?â
âThe pneumatic tubes carry papers and small objects around the building from floor to floor.â
âI figured thatâs what they did. But how do they work?â
âIâm sorry, I would love to talk some more, but there are people waiting,â he said.
Maybe he didnât want to admit he didnât know.

I decided I was done with the Da Vinci knight, so I put it on the returns cart and gave the rest of my call slips to the snobby English page. Then I turned my attention to John Deeâs mechanical beetle.
Iâd looked Dr. Dee up the night before. He sounded really cool. He was an English alchemist, mathematician, and spy in the sixteenth century, back when nobody quite knew the difference between science and sorcery.
I kind of wish I could have been a scientist then. My sister is always calling my experiments âalchemy,â and she doesnât mean it as a compliment. But I think I would have had a better time with science back when nobody objected if your invention had extra powers that nobody asked for or if you couldnât always explain exactly how youâd gotten them to work.
Dr. Deeâs beetle was the size of my fist, made of carved wood crammed with incredibly complicated clockwork. It kept doing things that shouldnât have been physically possibleâlike flying. The wings should be way too small for that heavy body. When I wound it up, though, it leapt out of
