Ladies to Kill

Billie, Mary Alice, Helen and Natalie have worked for The Museum, an elite network of assassins, for forty years. Now, their talents are considered obsolete, and in an era that relies on technology rather than human skill, no one appreciates what they have to offer.

When the four women are sent on an all-inclusive luxury cruise to celebrate their retirement, they become the target of an attack by one of their own. An order to eliminate a field agent can only come from the highest authority in The Museum, and the women realise they have been marked for death.
To get out alive, they must turn against their own organisation, relying on their experience and, above all, on each other. The secret to their survival is cooperation, and they are determined to teach their superiors what it really means to be a killer lady.
