Second series of this historical crime drama begins tonight on RTE, where the memory of Jack the Ripper is fading but the streets of east London are still as lawless as ever. Even a sergeant becomes the victim of a crime tonight, as Det. Insp. Reid struggles to keep order. Investigations lead to the newly emergent Chinatown, where Jackson discovers evidence of a devastatingly powerful opiate that could create havoc if released onto the streets. Those 'streets' by the way, may look familiar to you, as the show was filmed in Dublin.
