At 69 years old, Claire Reynolds is changing things up. She’s volunteering. She's learning to rollerblade. She’s rescued a shelter dog. And today, she’s killed a man. It wasn’t on her to-do list, but stuff happens. Besides, the man in question was strangling her good friend, Daphne, so what’s a gal to do? Scream, possibly. Call the cops. Or --- at retired officer Daphne’s insistence --- call in the rest of their senior gal pals, roll up the body in a blanket, and toss it off a cliff. The dead man is a member of the local crime family, and if the police get involved, it’s not just Daphne at risk, it’s all of them. But the body is just the start. Soon the Alphabet Girls --- Atsuko, Barbara, Claire and Daphne --- must transform into the Alphabet Sleuths if they’re to keep their liberty...and their lives.

1934, Dorset. Nothing gives postmistress Hester Smith greater joy than cycling through the idyllic village of Puddlington, delivering the mail to her neighbors. Bookish Hester has always felt privileged to witness the highs and lows a single letter can bring. But when war comes to Puddlington’s shores five years later, Hester suddenly finds herself in the devastating position of delivering news that no one should hear. As the community is directly impacted by tragedy on the battlefield and a shocking death occurs in the village, Hester’s spirit and resolve are tested like never before. Can she and her fellow Puddlington women, including the vicar’s wife and the bohemian lady of the manor, find the courage to face their darkest times and come through a storm that will change their lives forever?
