Mrs. Potter visits the Medicine Wheel Archaeological Camp near Cortez, Colorado, where she hopes to glean the wisdom of the ancients, and see some exciting ruins to boot. There's lots to see at the camp, and treats galore from Bingo, the cook, like Cream Cheese Corn Bread and Uncle Dick's Chicken. But trouble looms when a busload of youngsters disappears without a trace, drawing an eerie connection with the lost Anasazi tribe of so many years before. Then two women at Medicine Wheel end up dead. Are their deaths connected in some way? Who would want to harm them, and why? Mrs. Potter must take matters into her own hands as she investigates, hoping to avert another murder before it's too late.
