Maggie Messina, beloved owner of the Black Sheep Knitting Shop, is thrilled to be hosting a workshop for one of her former students, now a celebrity in the knitting world. But the celebration is upstaged when Amanda Goran, the owner of the rival Knitting Nest, is found dead in her shop on the other side of town.

Maggie had reasons to dislike Amanda, a thorn in her side ever since Maggie's shop surpassed Amanda's in popularity. Then again, it wasn't hard to dislike Amanda -- the contentious woman, whose marriage was on the rocks, seemed to specialize in causing misery all over town. But the pointed evidence has a detective casting a suspicious eye on Maggie. She may be a whiz at knitting, but can she keep the police from needling her before her shop, her reputation, and her circle of friends become unraveled?
