THIRD LEFT, pulsed the optic chip, Wintermute overriding her time display. FIVE DOWN. But she opened the top drawer first. It was no more than a shallow tray. Empty. The second was empty as well. The third, which was deeper, contained dull beads of solder and a small brown thing that looked like a human fingerbone. The fourth drawer held a damp-swollen copy of an obsolete technical manual in French and Japanese. In the fifth, behind the armored gauntlet of a heavy vacuum suit, she found the key. It was like a dull brass coin with a short hollow tube braised against one edge. She turned it slowly in her hand and Case saw that the interior of the tube was lined with studs and flanges. The letters CHUBB were molded across one face of the coin. The other was blank.
