Private investigator Marlo takes a case that seems ridiculous: a frantic man claims his elderly aunt was kidnapped over a legendary brownie recipe. But beneath the feud between two rival baking families lies something much deeper—a century-old secret, a code hidden in plain sight, and a war that was never really about dessert. As Marlo digs through family lies and long-buried truths, he discovers that some mysteries aren't meant to be solved, only savored. A witty, warm-hearted detective story about love, legacy, and the perfect brownie.
