Dead Of Winter by Stephen Mack Jones

 August Snow is a native Detroit guy.  A former policeman, Snow is now retired and a millionaire due to a civil settlement leading from an injury on the job.  Snow grew up in Mexicantown and one of his favorite places was Authentico Foods.  Ronaldo Ochoa, the founder of Authentico was a friend from back when the restaurant was just starting.  Now the restaurant has morphed into a company that supplies tortillas to restaurants throughout the area.

Ochoa asks Snow to come meet him.  To Snow's surprise, Ochoa asks Snow to buy his company.  Ochoa is older and ill and wants to assure that his company will survive to provide for his family.  He has been approached by a shadowy figure to buy him out and Ochoa fears that the proposed purchaser wants to raze the company and develop the area for the professionals who are starting to return to Detroit.  Snow isn't interested in buying but agrees to look around.

As he investigates, Snow starts to see that what Ochoa had feared is true and that violence isn't out of the question for the people behind the offer.  Soon Snow and his friends are caught up in a maelstrom of violence with assassins gunning for them.  Can Snow unravel the business and those behind it before he and his friends are killed?

This is the third August Snow novel.  Readers may find the violence a bit over the top and the lack of police follow-up after multiple killings is a sticking point.  Outside of that, the author explores the topic of gentrification in a realistic manner with the results of such development on those who already live in the area and who are forced out.  It is an interesting viewpoint from a detective of color and one whose roots in the black and Hispanic communities are deep.  This book is recommended for mystery readers.
