In this delightful new mystery our heroine Kat Stanford stumbles upon a hidden room in an abandoned wing at Honeychurch Hall.

However, Kat's initial excitement soon ends in horror. There, lying on the cold, stone floor, Kat comes across the body of a young woman dressed in an Egyptian toga and wearing a tawdry fairground trinket around her broken neck.

Suspicion falls on some of those who live at the Hall - both upstairs and down and even those who are just been passing through.

Matters come to a head as a killer lurks amid the aristocracy, and Downton Abbey fans will want more Killer Balls at Honeychurch Hall.
