This series keeps getting better and better! This is the fourth book, and Laurel now lives in the apartment above the funeral home. Since moving out, her mother decided to open her house as a B&B for extra income. In her own confusing way she has rented to 3 couples who are writers of ghost stories and thinks they are Theologians. (Well, they are interested in spirits...) Her disappointment is so keen that she decides to take a little road trip. Laurel is concerned she will get lost, and suggests she get a GPS specifically calling it a "Tom Tom." So what does Thelma do? She hires an escort and requests one named Tom, and accuses Laurel of stuttering! Wait! It gets better...but I guess you had better read this for yourself and find out about nude jumping wobbly bits. You will be glad you did, because this series has a lot of funny bits and progress between Laurel and Basil.
If you haven't read the others in the series, you owe it to yourself to read them now in order. Although the books are independent stories, they make a lot more sense when read in order and you meet the characters gradually.
