Played by William Sanderson
Eustace Bailey Farnum runs the Grand Central hotel, one of the main hubs of Deadwood. Just about every visitor to Deadwood ends up in Farnum's establishment at one time or another.
Appointed by the town's fathers as the default mayor - no one else wanted the job-Farnum has grandiose ideas about his prospects. The hotelier also has connections to Swearengen and is often involved in Al's swindles and schemes, but he has a difficult time getting Swearengen to take him seriously.
