Sarah Grayson owns Second Chance, a shop that sells lovingly refurbished items, in the charming town of North Harbor, Maine. But she couldn't run the store without the help of her right-hand man, Mac - or her dashing rescue cat, Elvis. Mac's life before North Harbor has always been a little bit mysterious, but it becomes a lot more intriguing when a woman from his past shows up in town, and then turns up dead. Suspicion falls on Mac, but Sarah - and Elvis - know he can't be the killer, and they hope they can prove his innocence quick as a whisker.
