Love, Lies & Liquor by M.C. Beaton
17th Agatha Raisin mystery
Agatha still carries a torch for her ex-husband, James Lacey, who is once again living next door. He invites her to a terrible bbq with his snobby friends. For once Agatha stands up for herself with James and leaves him with his rude friends. He then invites her on holiday to make up for the bbq. Unfortunately, the surprise destination is a rundown British seaside town, Snoth-on-Sea, in which James has fond memories of visiting as a child.
After an altercation a fellow guest at their hotel is murdered, strangled with Agatha's scarf. So Agatha is determined to clear her name. But fefore Agatha can make much headway in her investigation, two more guests are killed.
Typical Agatha style but for once stands up for herself when it comes to James and the other men in her life. While Agatha will never be perfect, she is starting to value her self worth.
