Someone on posh Callander Square will kill to keep a secret in this "superior" mystery from the New York Times–bestselling author of Twenty-One Days (The San Diego Union-Tribune).

When two dead infants are dug up in the Callander Square gardens, the upper-class residents dismiss the burials as the desperate act of a low-born girl and resent the intrusion of Inspector Thomas Pitt into their well-ordered lives. Pitt is not convinced that the case should be so easily dropped. Also intrigued by the mystery, Pitt's well-born wife, Charlotte, pursues her own investigation into places Thomas would never have access—the parlors and inner chambers of the mansions on the fashionable square. With her sister Emily, Lady Ashworth, who lives on Callander Square, she delves into the lives and secrets of the residents. Thomas and Charlotte, now expecting their first child, form the perfect sleuthing couple. Elegant closets soon spill their skeletons exposing long-hidden secrets—secrets that could lead even the most upright aristocrat to kill.

But will Pitt's keen investigative skills and Charlotte's insights into the workings of high-class society solve the mystery in time to save the innocent residents of Callander Square from the murderer among them? Callander Square is the 2nd book in the Charlotte and Thomas Pitt Novels, but you may enjoy reading the series in any order.
