Murders in the Cascades

During a lucid moment, an Alzheimer's patient tells amateur sleuth Biodina d'Angelo that 40 years ago he killed his lumberyard partner in the Cascades of Washington state. Biodina begins searching historical records, and a clever fraud scheme is uncovered, along with news articles about a missing lumberyard owner. Along the way, her intuitive nature and nosiness helps her uncover another murder of a well-respected record producer. Will the murderess be a starstruck performer, a jealous wife, or a vindictive assistant?
