Police Procedurals, Women Sleuths 

In Everyone Lies by AD Garrett, DCI Kate Simms is on the fast track to nowhere. Five years ago she helped a colleague when she shouldn't have, and she's been clawing her way back from a demotion ever since. Professor Nick Fennimore is a successful gambler, crime scene officer, chemistry graduate, toxicology specialist and one-time scientific advisor to the National Crime Faculty. He is the best there is, but ever since his wife and daughter disappeared he's been hiding away in Scotland, working as a forensics lecturer. In Manchester, drug addicts are turning up dead and Simms' superior is only too pleased to hand the problem to her. Then a celebrity dies and the media gets interested. Another overdose victim shows up, but this time the woman has been systematically beaten beyond identification. The evidence doesn't add up; Simms' superiors seem to be obstructing her investigation; everyone lies; and the one person she can't afford to associate with is the one man who can help: Fennimore. - from Amzon
