This book is number 17 in the Death on Demand Mystery series.
I really enjoy this who-done-it series by Carolyn Hart and number 17 is another hit. Most books in this series has some focus on Annie Darling's book store, but this one has less focus on the book shop when Annie goes undercover to do some investigating and set up a trap.
Annie's PI husband, Max, accepts a new case
and fails to come home, she's frantic and calls in all her friends,
including the police. The authorities organize an effective search that
leads to the body of an attractive woman near Max's abandoned car; in
the trunk is the murder weapon. Portrayed by the press as an unfaithful
husband and killer, Max is arrested as soon as he surfaces. That's when Annie and her friends go to work to hunt down a killer.
