I looked up from my textbook to see a man in a trenchcoat dash across the library lobby.  His fedora flew off as he ran, and his coat billowed out, revealing a well-fitted two-piece suit.  I spied three policemen slam open the front doors ten yards ahead of him, and he whirled on his heel and headed for the stairs.  I heard running feet on the stairwell, and he must have gone up both flights in five seconds, because the noise changed to feet on carpet.  The police dashed up behind him, shouting for him to stop.  I looked up around the mezzanine, and caught a flash of trenchcoat rounding a corner.  More police had gone up the back stairs, and I was getting more and more curious how this would turn out.  I, and the other students, craned our necks to see.
            POP!  A grapple shot out, broke one of the skylights, and found a purchase somewhere on the roof.  Glass tinkled onto the third table down from me, and some bioengineers ducked their heads.  The man doffed his trenchcoat on a third story balcony, revealing a shoulder holster with a silenced pistol  I couldn't see it very well, but it looked like an H&K Mark 12, a Navy SEAL gun.  He had a flat pack on his back, I hadn't noticed that under the trenchcoat.  He held onto his grapple launcher tightly (and here I thought those were just in cartoons and Bond movies), and gracefully swung out into the mezzanine, being pulled up towards the roof.  He was going pretty fast, but when the police began firing on him he was still able to shoot a few of their guns out of their hands.  I was pretty impressed.
            He got to the skylight and swung himself through.  I could hear him running on the roof, but it was rapidly drowned out by the sound of a helicopter.  The rotor wash blew through the broken skylight, and I grabbed my papers as they fluttered.  The helicopter's shadow darkened the windows, and then the rotor noise faded out.  A librarian was sobbing behind the front desk, and I walked over to her, passing between stunned students and police clutching their hands in pain.
            "What was that all about, miss?"  I asked the pretty, but somewhat plain, librarian.
            "It's gone…it's gone…" she moaned as she rocked back and forth on her stool.  Tears stained her cream blouse and plain skirt.  "He took it…it's gone…and to think…I…"
            The poor girl was verging on hysterics.  "Shh, it's okay.  You're alright, nobody got hurt.  What did he take?"  I patted her on the shoulder, trying to calm her shaking frame.
            "He took the…he took The Development and Growth of the Soybean Industry in Brazil by Philip F. Warnken, it was ISBN-13 978-0813821962…and now it's gone…" she wept bitterly.  I went back to my homework.
