Clatclit leading the way, we sidled through the right-hand gap, then he pressed the mammoth stone back into place.

"You're coming with me all the way?" I asked, surprised. Somehow, I'd thought his guideship ended at the same place the tunnel did.

Clatclit nodded vigorously.

"Is it that the Ancients don't trust me?"

Headshake.

"You have nothing better to do?"

Negative.

"Okay, I'll bite. Why?"

Clatclit stepped toward me, placed a hand on my shoulder, then placed his free hand over my heart, moved it over his own, held up two fingers and crossed them.

"Because we're friends," I said softly.
