If only this were a real TV show. I'd definitely watch crime solving librarians, wouldn't you?
Several years ago, when BCR's auditors kept pushing us to not be so dependent on OCLC revenue, we thought that a possible new service would be "assassin librarians." Who would ever suspect a librarian? We could send in a covert team, do the job and leave town -- a sort of L-Team (instead of A-Team).
