Billie, Helen, Mary Alice, and Natalie are back. The killers of a certain age (over 60) are a year into retirement when they discover someone is trying to kill them in repayment for an assignment they conducted for The Museum. What follows is an action-packed adventure full of intrigue, foreign travel, disguises, a live chicken, and lots of laughter amid the serious job of stopping a dangerous killer.
