Brewer certainly comes across as the strangest and least sympathetic character in Kolker's book (and that includes the Dr, even). In the book he sounds like he's trying to work some angle that will make him money- whether or not he actually knows what happened that night, he drops hints that for the right price he'll be willing to tell his tale. Super unsavory, and as presented in Lost Girls, definitely edging toward sociopathic (imo).
