Surprised that author Monica Ferris, mystery writer has not been mentioned. Her main character owns and operates a knitting shop...Blackwork (was not familiar with that craft, interesting) Knitting Bones; Frammed in Lace; Embroidered truths; Hanging by a thread; A murderous yarn; Unravedled sleeve; Sins and needles.
And Maggie Sefton: Knit one, kill two; A deadly yarn; A killer stitch; Needled to death.
Laura Childs: the Teaberry strangler; gunpower green; dragonwell dead; chamolile morning. ( Main character runs a tea shop).
And Emily Brightwell: Mrs. Jefferies a victorian mystery series: Mrs. J & the feast of St Stephen;...holds the trump.
First in a new series by Kirsta Davis: the Diva runs out of thyme.
