With never a moment to rest, the pursuit through space felt like a game of hounds and hares ... or was it follow the leader? After all, was it right for a single second, a single insignificant second, to destroy a man's life and his dream? So now he sat searching for a perhaps nonexistent red-bearded giant, and hoping and doubting and fearing, all at once.
