I've mentioned before the excellent French crime series Spiral which was shown a couple of times on BBC4. There are rumours that the second series will be on in the autumn (though it's autumn now, so...). In the meantime, the BBC have released a 2 disc box set of the first series. The going rate is £22.99.
When the badly beaten body of a young Romanian woman is discovered on a Parisian rubbish dump, the investigation plunges us deep into the murky worlds of prostitution, drugs, business, politics and justice...
The investigation is led by Pierre Clement, a young recently-named public prosecutor, who teams up with Police Captain Laure Bathaud and investigating magistrate Judge Roban - three indomitable characters with their own methods, beliefs, demons and visions of justice. As the young woman's identity and past life are gradually uncovered, it soon becomes apparent that her story is tied to a network of corruption touching the very people charged with uncovering the truth about her.
The BBC website for Spiral is here but doesn't mention the next series.
