The relaxing week away turns nightmarish early on when she startles an intruder at Bob’s family’s bed and breakfast. His aunt confesses that this isn’t the first break-in: it’s the fourth one in as many weeks. She has started to lose business as her guests no longer feel safe in the quaint, rural town.

As Cari pours her attention into finding the intruder, she realizes Bob is becoming increasingly distracted. Once again, she struggles to balance her love of sleuthing and her personal life. Can she save the family business and her relationship?
