Blue Murder

This is the first in a two-part crime drama, starring Caroline Quentin as detective and single mother Janine Lewis, who is forced to put her family concerns aside to investigate the murder of a deputy headmaster found disemboweled on his allotment.

Janine faces increasing pressure from her boss to conserve resources, narrow her investigation to one of three suspects, and conclude the case. But when her team turns up drug deals and homemade pornographic videos of the most violent sort, Janine insists on following the evidence and her instincts.
