It's a beautiful afternoon in May and set up for The Black Hills Fiber Gathering is in full swing. Martha Williamson, owner of The Spider's Web-a shop specializing in spinning and weaving, is looking forward to four glorious days of selling and talking fiber and fiber tools as she organizes her booth and gets her alpaca settled in their stall. Then Falcor, her Great Pyrenees, finds a body, and she is pulled into the agony of a terrible accident. Or is it? As one person after another seems to have reason for wanting the victim dead, Martha is more and more certain there was no accident. However if it was murder, who did it and why? When there is another attack and Martha is threatened, it becomes obvious that she needs to find the answers. With her steadfast Great Pyrenees, Denali and Falcor, by her side, Martha begins to unravel the mystery, but will she be fast enough to forestall a killer's hand?
