Book 4 in the Shady Acres Mysteries series
Right before Christmas, Shelby Hart is visited by the man who ditched her at the altar. It seems he wants the expensive gifts he'd given her to give to his new fiancé. Unfortunately for him, Shelby sold them. When the man shows up dead in a bed of poinsettia's, Shelby is thrust reluctantly into a group of women who call themselves the Second Mistress Club.
