All the Way Gone (Detective Annalisa Vega #4) by Joanna Schaffhausen
For fans of ex-cops turned PIs, multiple suspects, and thrillers!
Annalisa Vega has left the Chicago Police Department and is now a PI with a big case: Mara Delaney has written a book, soon to publish, arguing that there are good sociopaths and neurosurgeon Craig Canning is her proof. That is, until a woman in Canning’s building falls to her death, and Delaney starts to question her own beliefs. Now she needs to know if Canning is a murderer before the book’s publication date. Vega is on it, except she finds that even though the cops ruled this an accident, she’s suddenly in a cat-and-mouse game for answers.
If you want to start at the beginning of this series, pick up Gone for Good — Schaffhausen is one of the authors I reach for any time I want a solid mystery to get sucked into. She’s very good at characters and pacing.
