Billie, Mary Alice, Helen, and Natalie have worked for the Museum, an elite network of assassins, for forty years. Now their talents are considered old-school and no one appreciates what they have to offer in an age that relies more on technology than people skills.
When the foursome is sent on an all-expenses paid vacation to mark their retirement, they are targeted by one of their own. Only the Board, the top-level members of the Museum, can order the termination of field agents, and the women realize they've been marked for death.
Now to get out alive they have to turn against their own organization, relying on experience and each other to get the job done, knowing that working together is the secret to their survival. They're about to teach the Board what it really means to be a woman--and a killer--of a certain age.
This is an entertaining story. Four woman in their sixties who are trying to figure out why they've been targeted for death and what to do about it. What I feel is really well done is how they constantly have to deal with the limitations of their age. Not being agile as they once were, hot flashes, taking longer than usual to recover from aches and pains, plus their limited ability in a hand to hand fight.
Killers of a Certain Age, is a terrific escapist read.
