Kate Foster runs the Summerside Inn (and her life) by well-organized checklists: 

• Make sure the caterers don’t serve devil’s food cake to the Christian Women’s Alliance - check
• Tell my mother that having a séance to get rid of any unwanted spirits in the kitchen during dinnertime is not okay - check
• Send a friendly reminder to all staff that the pens are color coded for everyone’s enjoyment, and therefore it is not a good idea to put them all in one jar in order to “spice things up” as was anonymously suggested - check

But, when an acclaimed hotel critic dies at the inn just before she’s about to publish a scathing review that would ruin the business, Kate’s life and checklists are thrown into disarray. And it doesn’t help matters that the detective assigned to the case is messy, unorganized, and too charming for his own good. 

Now Kate has to prove her innocence and save her inn or else the only thing that she’ll be organizing is the prison’s next bake sale.
