The Secret of Chimneys

The council chambers at Chimneys, the Brent family estate, holds a dark and intriguing secret and someone will stop at nothing to prevent the monarchy being restored in faraway Herzoslovakia.
A young drifter finds more than he bargained for when he agrees to deliver a parcel to an English country estate. Little did Anthony Cade suspect that a simple errand on behalf of a friend would make him the centrepiece of a murderous international conspiracy. A sinister plot rife with diamonds, oil concessions, exiled royalty, an elusive master criminal and the combined forces of Scotland Yard and the French Sûreté.
“There is more than murder in this story; there is a treasure hunt in it, not for gold but a diamond, and the story is suitably staged for the main part at Chimneys, that historic mansion whose secret will be found.”
