If hooks could kill / Betty Hechtman.

Enhanced descriptions from Syndetics:

When a television crew comes to Tarzana, Molly Pink and the rest of her crochet group, the Tarzana Hookers, deal with the inconvenience as best they can. But when one of their own goes down, Molly has to figure out who would want to turn a Tarzana residence into a real life crime scene...

With a little showbiz razzle-dazzle, television crime show L.A. 911 has taken some of the community's most mundane locations and turned them into cinematic backdrops, including the yard of Kelly Donahue. The Tarzana Hookers' newest member can't always make the group meetings, so when collecting crocheted items to sell at the local Jungle Days street fair, Molly and the gang know better than to expect an appearance from Kelly. Instead, they decide to visit her at home to pick up her goodies--only to soon be ushered out due to the television crew's commotion.

Kelly's cache of unique crocheted creations is a welcome addition to their fair booty, but the news the Hookers get later that day isn't welcome at all. It seems someone silenced Kelly--permanently--and no one heard a thing. With no solid leads, Molly decides to conduct her own investigation. Now, she and her pals will have to quickly stitch together the clues to catch Kelly's cold-blooded murderer--before someone else dials 911.
