Whitechapel will be broadcast on ITV at 9pm from the 2nd of February for three weeks. Alex plays Commander Anderson.
"A series of bloody, tragic and impossible crimes suggest someone is carrying out copycat Jack the Ripper murders 120 years after the killer first struck..." So not one for the faint hearted then.
There are more details on the ITV minisite for the programme. The press release with details of the first two episodes can be found here.
