Three women have been strangled in their homes, and it appears to be the work of the same sadistic killer.

The victims' neighbors and friends don't seem to remember anything unusual or suspicious, and Maeve is almost at a loss about how to move forward with the investigation.Then the evidence starts to point to a shocking suspect: DCI Josh Derwent, Maeve's partner on the police force.
