Having bought and shown the excellent The Killing (still to be completed in this household at the time of writing), BBC Four are following it up with double episodes of series 3 of...Spiral.
The Butcher of La Villette begins next Saturday at 9pm on BBC Four.
When the body of a young woman is found murdered and mutilated, police captain Laure Berthaud seizes the opportunity to redeem a tarnished reputation and leads her squad on the hunt for the sadistic killer. Meanwhile, Judge Roban's investigation into the case of a child being bitten by a dog might turn out to have broader implications, and even public prosecutor Pierre Clement is not immune from the resulting pressure.
The first two series can be bought on DVD as a boxed set for £16 on amazon.co.uk or play.com.
