The Secret of Bow Lane (A Below Stairs Mystery)

In Victorian-era London, amateur sleuth and cook Kat Holloway must solve a murder to claim an inheritance she didn’t know she had in a riveting new historical mystery from the New York Times bestselling author of Death at the Crystal Palace
A stranger who appears on Kat's doorstep turns out to be one Charlotte Bristow, legal wife of Joe Bristow, the man Kat once believed herself married to—who she thought died at sea twelve years ago. Kat is jolted by Charlotte’s claims that not only was Joe murdered, but he had amassed a small fortune before he died. Charlotte makes the cook an offer she cannot refuse—if Kat can discover the identity of Joe's murderer, Charlotte will give her a share of the fortune Joe left behind.
With the help of Daniel McAdam, her attractive and charismatic confidante, Kat plunges into her own past to investigate. When it becomes apparent that the case of Joe’s death goes far deeper than simple, opportunistic theft, Kat and Daniel's relationship is put to the test, and Kat herself comes under scrutiny as her connection to Joe is uncovered. She must race to catch the real killer before she loses her job and possibly her life.
