I tried my most authoritative voice.
"Lieutenant Botoes," I ordered, "put on a suit, and come out here."
He laughed.
"Think you've got me, don't you? You toppled the ship over, and killed Raul, then you pushed Geoff out of himself, and took him over. I'm the only obstacle now, aren't I? But you haven't got me yet. I'll soon show you."
Then there was a clang that hurt my ears. I guessed he had been holding the helmet to speak into its radio, and had now dropped it. Then I saw the outer door of the lock swing shut. I ran to it, and battered on it, telling him not to be a fool.

Even encumbered with the suit, I covered the ground with great, leaping strides a dozen yards long, and was some eighty yards away in a few seconds, before I misjudged my step, and fell.
Still sprawling, I looked back at the Figurao. A cloud of dust and sand was spurting from beneath her forepart. Some of the grit was pattering on my helmet. As I watched, the forepart swayed, and then lifted clear of the
