Anyway, everything was neat and tidy in Bobby Shaftoe’s mind until he met two of the men in Detachment 2702: Enoch Root and Lawrence Pritchard Waterhouse. He can’t put his finger on what bugs him about those two. During the weeks they spent together on Qwghlm, he spent a lot of time listening to them yammer at each other, and began to suspect that there might be a third category of man, a kind so rare that Shaftoe never met any of them until now.
