While looking for books written by local authors, I found a mystery series by an Oregonian, Arlene Sachitano. It's the Loose Threads Mystery series and tells the tales of Harriet Truman and her quilting group. There are 8 books in the series at this point, and I've recently read and thoroughly enjoyed the first 3.
Quilt As Desired is the first book and soon after Harriet arrives, her house and studio are trashed during a break-in. The thief was looking for something and apparently didn't find whatever it was. Then Aunt Beth's best friend and fellow quilter is murdered. Harriet begins to investigate with the help of her aunt's quilting friends, the Loose Threads.
The second book is Quilter's Knot and the Loose Threads are off to a quilting retreat at Angel Harbor Folk Art School to learn new techniques. One of their group, Lauren, has been attending a two-year program at the school and has a special exhibition. However, among accusations of design copying and fraud, Harriet and the Threads have to try to salvage Lauren's reputation. It doesn't help that the school's founder collapses during a class and is found to have been poisoned.
In the third book, Quilt As You Go, Harriet has helped organize a Civil War re-enactment and festival as part of the local merchant's group. During the event, a man is found dead and it's discovered that he is closely connected with Loose Threads member, Mavis. Secrets are revealed that have been hidden for over 20 years and Harriet and the Threads are right in the middle of things.
