RIPPER STREET
BBC America, 9:00 p.m. ET
In this third episode of this new British import (already renewed for a Season 2, by the way), there’s a killer on the loose, stacking up bodies in the East London morgue. But this time the serial killer in this period drama isn’t a Jack the Ripper-type madman – it’s cholera. Even so, its source is a case our intrepid detectives desperately rush to solve.
