The Secret of Chimneys

Adventurer Anthony Cade takes on a simple courier job delivering a set of memoirs to a London publisher, only to find himself tangled in blackmail, stolen jewels, and a plot involving the fictional Balkan state of Herzoslovakia. When a house party at the country estate of Chimneys turns to murder, Superintendent Battle must untangle a web of secret identities and hidden pasts before the killer strikes again. Blending country-house mystery with international intrigue, this early Christie novel is a lighthearted, fast-moving puzzle full of disguises and double-crosses.
