This is the third book in the Aggie Morton, Mystery Queen series, inspired by the life of Agatha Christie as a child and her most popular creation, Hercule Poirot. Aspiring writer Aggie Morton is ready to enjoy an invigorating trip to a Yorkshire spa, where her widowed mother can take the waters and recover from a long mourning period. Having solved yet another murder - not to mention rescuing her best friend Hector from certain death - over Christmas, Aggie is looking forward to more splendid adventures with Hector, who has joined Aggie, her mother and Grannie Jane on this trip.
