Dial P For Poison (Movie Club Mysteries, Book 1)

"My career in the San Francisco PD ended the day I arrested my husband."
Maggie Doyle gives her cheating ex and crumbling career in the San Francisco PD the proverbial middle finger, and moves to the Wild West...of Ireland.
Lured by her aunt's promise of a restful Irish vacation, Maggie agrees to help out at the Movie Theater Café in exchange for bed and board. Things are looking up-until the most hated woman on Whisper Island is poisoned at the café. With her aunt as the prime suspect, Maggie and her rock-hard muffins are hurled into the murder investigation.
With the help of her UFO-enthusiast friend, a nun, and a feral puppy, Maggie is determined to clear her aunt's name. Can she catch the murderer before they strike again? Or will her terrible baking skills burn down the cafe first?
