When her beloved nanny, Hannah, left without a trace in the summer of 1988, seven-year-old Jocelyn Holt was devastated. Haunted by the loss, Jo grew up bitter and distant, and eventually left her parents and Lake Hall, their faded aristocratic home, behind.

Thirty years later, Jo returns to the house and is forced to confront her troubled relationship with her mother. But when human remains are accidentally uncovered in a lake on the estate, Jo begins to question everything she thought she knew.

Then an unexpected visitor knocks on the door and Jo’s world is destroyed again. Desperate to piece together the gaping holes in her memory, Jo must uncover who her nanny really was, why she left, and if she can trust her own mother…

In this compulsively readable tale of secrets, lies, and deception, Gilly Macmillan explores the darkest impulses and desires of the human heart. Diabolically clever, The Nanny reminds us that sometimes the truth hurts so much you’d rather hear the lie.


[A] devastating psychological thriller. Macmillan expertly ratchets up the tension as long-held secrets come to light. Readers will have a tough time putting this one down.

Publishers Weekly

Classism, fragile memories and a family torn apart by misunderstandings and jealousy haunt an aristocratic British family in “The Nanny,” Gilly Macmillan’s enthralling fifth novel. Sophisticated plotting and believable characters elevate “The Nanny” as a solid family drama... the real strength of “The Nanny” is the mother-daughter relationship and how feelings can be manipulated... Macmillan wisely doles out clues leading to a surprising finale in the character-driven “The Nanny”.

Associated Press

Macmillan fills the story with unreliable characters and red herrings. There’s also delicious British suspense tropes on display: rural resentment of the local rich people, closets full of skeletons, shady business dealings, false memories, fake identities. Who could ask for more?
