Dyer Consquences by Maggie Sefton.
In the fifth volume of the Kelly Flynn Knitting mysteries, all sorts of mishaps befall Kelly. Her home has been vandalized, a fire has been set on the ranch she recently purchased, and her dog has been poisoned. Kelly is convinced that someone has a vendetta against her, but when a young woman dies in the basement of the House of Lambspun she begins to reconsider.
I didn't enjoy this as much as the earlier books in the series. Characterization depends too much on the reader's knowledge from descriptions in the previous books. Additionally, the plot seemed to depend waaaay too much on coincidences.
I'm hoping this is an aberration in an otherwise decent series.
