I have been a fan of Rupert Penry-Jones since watching his performance in Persuasion where he played the dashing Captain Frederick Wentworth. In Whitechapel though, Penry-Jones finds himself playing a very different role indeed. He is still dashing, and smartly-dressed in Savile Row suits, but his rank as a newly-minted DI on the fast track inadvertently places him on a case that turns out to be a serial murder mimicking the gruesome crimes of Jack the Ripper.
DI Joseph Chandler is being groomed for the HQ and as part of this training, is expected to pay his dues with a brief stint as a DI on a case that initially appears to be open and shut. The DI finds himself in unfamiliar territory and is looked upon with derision by the cynical DS Ray Miles (Phil Davis) and the other members of the team. The series is broken up into three episodes and each episode sees the team puzzling out the case which gets even more complicated when the team realizes that this is indeed a copycat killing of the Jack the Ripper murders, which means more victims will be targeted soon enough.
