Harley Granger has a gift for seeing things that others miss. He wasn't much of a novelist, but his work as a true crime author and podcaster has earned him fame and wealth—and some serious criticism for his various unethical practices. Still, visiting Little Valley to be closer to his dying father has caused him to look into a case that many people think is closed—and some want reopened.

It’s the most wonderful time of the year...but not for Maelyn Jones. She’s living with her parents, hates her going-nowhere job, and has just made a romantic error of epic proportions. But perhaps worst of all, this is the last Christmas Mae will be at her favorite place in the world - the snowy Utah cabin where she and her family have spent every holiday since she was born, along with two other beloved families.

Fiona, Sue, and Daisy, three retired ladies who volunteer at the local charity shop, Dogs Need Nice Homes, can’t believe their favorite customer is dead. Eighty-six-year-old Sarah Brown was found murdered in her hallway by her delivery man, a domino clutched in her hand—with a name scratched on it. When another person is found dead with a domino in their hand, and with the police making no progress, the ladies will need to help unmask a serial killer. At least they have Fiona’s scruffy-haired terrier cross to assist them.

To solve an impossible murder, you need an impossible hero … Seventy-seven-year-old Judith Potts is blissfully happy. She lives alone in a faded mansion in Marlow, sets crosswords for The Times, and there's no man in her life to tell her what to do or how much whisky to drink. One evening, while out swimming in the Thames, Judith witnesses a brutal murder. When the local police don't believe her story, Judith and two unlikely friends decide to investigate for themselves. Together, they are the Marlow Murder Club.

Maisie Dobbs got her start as a maid in an aristocratic London household when she was thirteen. Her employer, suffragette Lady Rowan Compton, soon became her patron, taking the remarkably bright youngster under her wing. Lady Rowan’s friend, Maurice Blanche, often retained as an investigator by the European elite, recognized Maisie’s intuitive gifts. The outbreak of war changed everything. Ten years after the Armistice, in the spring of 1929, Maisie sets out on her own as a private investigator, one who has learned that coincidences are meaningful, and truth elusive.
