Steve's lips twitched downwards, not seeing what Stark was looking so pleased about. It didn't seem nearly so obvious to him. Still, he didn't want Stark to think he hadn't been paying attention. As near as he could tell the thief had to be either a member of the crew or wa stow away.
"Well," he began, "The thief has targeted both the upper and lower classes, so his motive would likely be oppertunity. They've stolen from the crew and well, even the Captain, meaning they have been able to move about the ship freely. The only persons of note that have not been touched would be Lord Bordeaux and his daughter, but they have been cleared. Old family, criminal background, but nothing was ever proven and their cabins have been searched repeatedly. So I've no idea who to suspect, though apparently it is quite plain to you."
