Did I Infect The Ghost?

Or, Space Eggz

A foreign visitor on a spaceship tells the captain and his crew a made up story about their own efforts to solve a disaster or mystery which nobody can identify.

This is not a series; it is the only book with this title. The captain of a spaceship listens to a long, condescending, made up story about himself, which poses questions about the construction of one’s identity and the world.
