From the author of The Girl in the Green Dress comes a delightful and captivating novel about a fictional murder mystery at the iconic Macy's parade leading up to the holidays in historic New York City.

New York, 1932. Grace Verlander is the secret beating heart of Macy's. She's the "assistant to the assistant to the someone who's in charge," the go-to person for keeping everything running smoothly behind the scenes at the famous, bustling store.

It's not every day you get a letter from Santa Claus, but three days before Macy's annual Thanksgiving Day Parade, Grace arrives at work to find a note from the store Santa Claus in her locker: someone has sent him a death threat. Shocked, Grace promises to look into it and speaks to the store detective about the parade's security, confident that they've found a solution that will keep everyone safe. But on the day of the parade, despite all their precautions, a dead body is found on one of the floats.

Using her wits and deep knowledge of the ways of the place, Grace is determined to find the killer and seek justice―not just for the dead man, but to save the reputation of this iconic store from ruin.

Steeped in glittering glamour and nostalgic wonder, this is a remarkable, unpredictable mystery set in the evocative world of one of New York's most memorable institutions.
