The story kicks off when Reverend Bob Knudson and his wife, Claire, embark on a long-awaited honeymoon. To fill in during their absence, Bob's childhood friend, Matthew Walters, a Lutheran minister with a penchant for sweets, arrives in town. However, the serene setup takes a dark turn when Hannah discovers Matthew dead in the rectory, face-down in a plate of Devil’s Food Cake, a single bullet wound marking his demise. The only witness? A mynah bird that cryptically squawks, “The wages of sin is death.” Determined to uncover the truth, Hannah delves into Matthew’s past, uncovering secrets that suggest his life was far from saintly. As she navigates a web of suspects, including a paroled convict cousin and a mysterious dollar coin, Hannah must sift through the clues to find the killer before they strike again.
