Book ~ "Black and Blue" (2019) David Rosenfelt

From Goodreads ~ Doug Brock hasn't had it easy since his getting shot in the line of duty as a New Jersey state police officer. Between the amnesia and having to solve two murder cases, it hasn't been the most restful recovery. He's slowly earning back the trust of his girlfriend, Jessie, since he doesn't remember their breakup, and has focused on new crimes with his partner, Nate.

But now an old case of Doug's has resurfaced and it's up to Doug to retrace his steps - steps he can't remember - to solve the case. Eighteen months ago, Walter Brookings was shot through the heart. With no clear motive and no similar murders, the investigation stalled and became a cold case.

When another man is murdered in the same fashion and the ballistics come back as a match, Doug begins to reinvestigate, and starts to question his own actions from the previous investigation.

Finally, what Doug uncovers may be more dangerous than any case he's faced yet.

Doug Brock is a state police officer suffering from amnesia after being shot ... he can't remember anything from the last ten years.  He is back to work, partnered again with Nate, and living with his former fiancée, Jessie, who is also a police officer.

A fairly well-to-do lawyer is fatally shot in the chest.  This is similar to the murder of a man who was shot 18 months ago.  Doing some research, Jessie determines a potential suspect is a man named Danny Phelan ... he was a sharp shooter in the army and has just gotten out of prison after spending about 18 months there on drug charges.  The murdered lawyer was Phelan's ex-wife's lawyer.  Then other people connected to Phelan in one way or another start getting murdered and Phelan seems to be on the run.  Doug and Nate don't think it's a coincidence.

I liked the writing style as it was funny, sarcastic and amusing at times.  It was written in first person perspective in Doug's voice but switches over to third person perspective when Doug isn't part of the action.  I liked Doug, Nate and Jessie and their humorous interactions with each other.

This is the third in the Doug Brock series and you don't have to have read the first ones as it works as a stand alone.  The author also writes a series featuring lawyer Andy Carpenter ... I've read and enjoyed all in that series.  It was fun to have Andy cross over into this book ... he is Phelan's lawyer and believes his client is innocent. 

I look forward to more in this series.
