Tommy & Evelyn Christie were hoping for a break from solving murders when they agreed to host Aunt Victoria and her daughters, Madeleine and Elise at their London home in Belgrave Square.

Recently widowed Victoria has returned from France for the London Season and to mend bridges with her estranged family.

None of them were prepared for the doubly shocking sight of a newborn baby and a dead body on the back doorstep of their imposing London residence.

Tommy & Evelyn face a race against time to solve the murder and the mystery of the abandoned baby before cousin Madeleine's London Season is ruined.
