Sheriff Jack Carter is the lone “normal” person in a town full of geniuses.
Henry Deacon is a scientist who serves as Eureka’s mayor/coroner/forensics expert/mechanic.
Crazy things happen in Eureka, and Henry is always on hand to help Carter figure out why things are blowing up.
And he’s always happy to explain to Jack, in plain English, what’s happening.
And over the years, a mutual respect and a deep friendship has grown.
