Mary Minor "Harry" Haristeen is back with sleuthing cats Mrs. Murphy and Pewter, and corgi Tee Tucker. And this time they must catch a killer determined to turn a birthday party into a funeral.Harry's beloved and tart-tongued Aunt Tally is about to turn the big 1-0-0. The alumnae association of her alma mater sees an opportunity to honor the event and make some loot off the centennial as well. The plan is to hold a big fund-raiser in Aunt Tally's honor to recoup some of the school revenue lost in the cratered economy. But soon there's more at risk than investments and endowments.
