Characters
Hercule Poirot
The world-renowned Belgian private detective, unsurpassed in his intelligence and understanding of the criminal mind, respected and admired by police forces and heads of state across the globe. Famous as much for his magnificent moustaches as his little grey cells.
Miss Marple
The sweet little old lady from St Mary Mead with an uncanny knack for solving crimes that baffle the police. Her seemingly sheltered village life in fact provides a microcosm of human nature that forms the basis of her intuitive deductions.
Tommy & Tuppence
The two young sleuths who, jobless and restless after the end of World War I, set up the Young Adventurers Ltd and consequently get mixed up with thefts, murders and international spies. The only characters in the Christie canon to age and live their lives in real time.
Ariadne Oliver
A foremost writer of crime and other sensational stories, often stumped by the exploits of her fictional Finnish detective Sven Hjerson. She accompanies Poirot on several of his most famous cases, offering solutions based on her astute female intuition.
Harley Quin
A strange trick of the light? Or a figment of the imagination? The mysterious Mr Quin appears to his friend Mr Satterthwaite at just the right moment to aid him in solving crimes, often with carefully worded but apparently random observations that provide insight into a problem.
Parker Pyne
Parker Pyne is not really a detective at all. In fact, he specialises in detecting and curing unhappiness in the discontented and guilt-ridden. Assisting the lovelorn, he considers himself a “heart specialist”.
