When Murder Comes Home (Aileen and Callan Murder Mysteries Book 1) by Shana Frost

Running her gran’s loss-making inn is a huge responsibility. Aileen Mackinnon has the business skills, but she needs to learn—hospitality for when the guests check in; murder investigation for when they die. Dying guests are bad for business, especially when the inspector claims you’re housing a murderer. With her gran’s precious inn at stake, Aileen Mackinnon goes on a crusade—to find the killer & annoy the frustrating (very handsome) inspector while she’s at it.
