Spring has sprung in Arborville, New Jersey, and Pamela Paterson and Bettina Fraser are keeping busy with their knitting group, Knit and Nibble. But it looks like April showers have brought May murders . . .

Fiber artist Ingrid Barrick has just been found dead in her ransacked house, but the fact that she'd seemed a bit troubled lately—and had been obsessively doodling pictures of bees—has the Knit and Nibblers wondering if this was really a burglary gone bad like the police think. There had been tension with a neighbor who was fuming (and sneezing) over the ragweed in Ingrid's garden—but allergies don't seem like grounds for murder.

As they chat with a local beekeeper, learn more about Ingrid's knitwear-designer ex, and look into a suddenly cancelled tapestry exhibit, Pamela and Bettina are intrigued to find more nature-themed sketches by Ingrid. The question is which of these many threads will lead to the truth about her unnatural death . . .
