It's springtime in Foggy Point, and the parks and recreation department is hosting a festival in conjunction with a local birdwatching organization. Harriet Truman and her quilting group, the Loose Threads, have been recruited to create items to raise money for the birdwatchers and teach classes to the youngsters attending the event. What could possibly go wrong?

Before the event begins, however, Harriet and Lauren find volunteer Maylene Harris dead on one of the forest hiking trails; a victim of a fentanyl overdose-and that's only the beginning!

Who is bringing drugs into Foggy Point? Harriet and the Loose Threads are determined to find out, but will this be the investigation they won't survive?
