Part 1 - Bryher (first section)

Timing follows on from Far from the Spaceports. It opens with Mitnash and Slate back on the Scilly Isles asteroids, after an inconclusive venture to Callisto. They become aware of a recurrence of the same problem. this time on the Martian moon Phobos. At the same time blackmail demands appear, from a group identifying itself as Robin's Rebels. Are the two connected? And if so, is this an old adversary, or a new one?

The investigation will go from asteroidal Bryher, to Mars and its unusual moon Phobos. and finally back to the Scilly Isles for the culmination.
