I dropped my flitterboat on the landing field and looked around without any hope of seeing anything. I didn't. The field was about the size of a football field, a bright, shiny expanse of rough-polished metal, carved and smoothed flat from the nickel-iron of the planetoid itself. It not only served as a landing field, but as a reflector beacon, a mirror that flashed out the sun's reflection as the planetoid turned slowly on its axis. I'd homed in on that beacon, and now I was sitting on it.

There wasn't a soul in sight. Off to one end of the rectangular field was a single dome, a hemisphere about twenty feet in diameter and half as high. Nothing else.

I sighed and flipped on the magnetic anchor, which grabbed hold of the metal beneath me and held the flitterboat tightly to the surface. Then I cut the drive, plugged in the telephone, and punched for "Local."

The automatic finder searched around for the Ravenhurst tickler signal, found it, and sent out a beep along the same channel.

I waited while the thing beeped twice. There was a click, and a voice said: "Raven's Rest. Yes?" It wasn't Ravenhurst.

I said: "This is Daniel Oak. I want to talk to Mr. Ravenhurst."

"Mr. Oak? But you weren't expected until tomorrow."

"Fine. I'm early. Let me talk to Ravenhurst."

"But Mr. Ravenhurst wasn't expecting you to—"

I got all-of-a-sudden exasperated. "Unless your instruments are running on secondhand flashlight batteries, you've known I was coming for the past half hour. I followed Ravenhurst's instructions not to use radio, but he should know I'm here by this time. He told me to come as fast as possible, and I followed those instructions, too. I always follow instructions when I'm paid enough.
