Avery Black used to be a top-notch defence lawyer. The best. Too good. She even managed to get a serial killer acquitted when it was obvious to everyone he was as guilty as Hell.
When he killed again, she was distraught. She had convinced not only the jurors but herself that he was innocent - or at least had not been proven guilty.
She gave up her career as a lawyer and enlisted as a cop with the Boston Police Department. Where of course she was scorned and sneered at by one and all. However, her ultra-sharp mind and her conscientious approach carry her slowly but surely up through the ranks to Detective. Now she has been transferred to the Homicide Squad, given a handsome new partner - the only one who would agree to work with her, the Chief tells her - and assigned as Lead-Detective to a staged murder that bears all the marks of being the first in a series of such staged murders. Or maybe the killer has already struck elsewhere, in another State.
I like Avery, and of course identified with her from the word Go. Which meant I was put through the wringer alongside her as Blake Pierce took great pleasure in applying the Kurt Vonnegut dictum to his leading lady.
