But no one’s inside. Just in case, I step over to the closest rack, where the smallest guns are stored. At the top are tiny pistols. I wasn’t kidding when I taunted Luthor. My father raised me to know what a gun is and how to use it. I pick up one of the red protection plastic bags and slide my finger through the seal. Gun oil wafts around me as I tip the bag open and the revolver falls into my hand. It has a small frame and a snubbed barrel, but it can hold .38 caliber bullets. The bullets are stored in a separate box, sealed with plastic. I press the grip into my palm as I load the gun. My hand’s too small to fit it comfortably, but the gun’s a double action, and all I’ve got to reach is the trigger.

I look closer, behind the shelves, the gun firmly in my hand. But no one is here.

Then I remember—I came here because I heard a door slam shut. Whoever was here may have started in the armory, but he slammed another door—on this hallway full of doors that are supposed to be locked.

I go back out and check the hatch through the bubble window, then open the room with the space suits. Nothing. I press my ear against the big door at the end of the hall, the last locked door, but it’s too heavy for me to hear anything.

What’s behind that door anyway? I briefly consider staying here to guard it. Whoever went in will have to go out. No one passed me as I raced through the hallway, and the only doors that can slam shut rather than zip open are these. Whoever it is has to be here.

Except . . . if this person knows how to unlock the doors, then whoever it is must also know about the stairs I found behind the walls . . . they go down too. They must reach the cryo level. And since there are no stairs here—they have to come out behind this last locked door. If I go up to the Feeder Level right now and run down the stairs, maybe I can catch whoever’s been tampering with Orion’s clues and discover what else is behind the locked door! If only Elder were here with me. . . .

I’m halfway down the hall when I remember the armory’s still open, and even with a gun in hand, it’s still not safe. I turn back and start to shut the door when I notice something: a floppy flashing near the shelf of explosives. I set the gun down and pick up the floppy.

Orion’s face fills the screen.
