Posson was the engineer in the Bean’s team that salvaged the Adjan hulk.

She wasn’t impressed with his appearance.  I went through to the dining room, where Posson was lounging at the table behind a lot of dirty plates, with a mug in his hand.  He was a small man, who looked as if he hadn’t shaved, or combed his greying hair, for several days.  His Scientist’s uniform had streaks of dirt all over, and food stains down the front. See the Bean’s Report A.

Elizana told the Bean:  He looks a bit of a slob, but he’s an excellent engineer.  He knows all about ships. Elizana, in the Bean’s Report A.
