The Secret of Chimneys is a work of detective fiction by British writer Agatha Christie, first published in the UK.
A young drifter finds more than he bargained for when he agrees to deliver a parcel to an English country house. Little did Anthony Cade suspect that a simple errand on behalf of a friend would make him the center piece of a murderous international conspiracy.
The combined forces of Scotland Yard and the French Surete can do no better than go in circles - until the final murder at Chimneys, the great country estate that yields up an amazing secret.
