The Patient by Tim Sullivan

In this third book in the DS Cross series, George and his colleagues Ottey and Mackenzie investigate the death of a young woman named Flick after her mother, Sandra, repeatedly tries to tell the authorities that she was murdered rather than having died of a drug overdose. The team finds evidence that seems to support her claim, along with several suspects that deserve a look. The Patient is a satisfying police procedural that continues to develop the personal relationship between George, Ottey, and Mackenzie. Give to readers who enjoy Ann Cleeves and Peter Robinson.
