CSI - Georgian London.
No that's not what they call it. It's really called City of Vice and its on Channel 4 at moment. As a criminologist i'm not able to comment on the historical accuracy and many would take issues with whether the work of the Fielding brothers amounted to a police force. From one episode though I like the apparently very modern nature of the crimes and lifestyles depicted. This sits well with my belief there was no 'golden age' that was crime free. In the week the Ipswich murders of prostitutes coming to trial it is a sad coincidence that the first episode ws about just that.
