View source for Extra Fingers

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.  [[Polymorph]]s are the only ones exempt from the ban.
