Detectives may be born with extra fingers (be polydactyl), eventually duplicating all the fingers (but not the thumb) for a total of eight per hand. All fingers are operational, and each hand will match the other (there is no different number of fingers on each hand). This however affects the Detective so that the only place they can be put (and they go in gladly, unusually) is Riot Control. Riot Control Canmephians are huge, strong, and aggressive. Riot Control Canmephians are banned from drinking any alcohol -- which is taken in stride, because part of their job is to perform executions. Polymorphs are the only ones exempt from the ban.
