Thank Goodness It's Fiber: That's the name of the spunky group of fiber and needlework artists founded by Ivy McClellan, Kath's beloved grandmother. Though Ivy has recently passed on, the members still meet regularly at her fiber and fabric shop, The Weaver's Cat, which Kath has now inherited.

It turns out the specter has just as much interest in solving the murder as Kath. So, with a little help from the members of TGIF—and a stubborn spirit from beyond—she sets out to unravel the clues and hook the real killer . . .
