Series 3 is set in 1894. The crime-fighting team of Reid, Drake and Jackson has fallen apart, and each man gone their separate way. Drake has moved to Manchester in search of a new life and a better existence as a man of the law; Jackson has reverted back to the man Reid found hopeless in a Tenter Street brothel; and Reid has retreated deep into his own mind, policing Whitechapel with a level of obsession that leads even his chief inspector to fear for him.
