This is part three of Blue Ice. Anton deGama is in the rings of Saturn, preparing a harvest of yellow plants on a chunk of ice the size of a football field, when his colleague Kellerman reports that she can see a patch of blue - and that it is moving...
Kellerman's comment made no sense. All round him the ice shone with yellow petals, drinking in the thin sunlight. He could see no hint of anything amiss. Except... the equator had a faint cyanic tinge that had not been there before.
His helmet hissed again. "DeGama? I've got my scope on your rock. That blue colour is definitely moving."
Anton swore unthinkingly into his mike, evoking a sharp protest from Kellerman. Nothing – in his not inconsiderable experience – could make a chunk of ice change colour, except human action. And no one else had any right to be on this fragment.
"DeGama, that blue is moving your way." Kellerman's usually calm voice was carrying more than a trace of worry. A corner of Anton's mind registered that she did care about him, after all, but he was more concerned about avoiding his flowers as he walked across the ring chunk towards the mystery.
As always, comments appreciated!
