Mr. Harley Quin
|First appearance||The Mysterious Mr Quin|
|Created by||Agatha Christie|
Harley Quin is a fictional character created by Agatha Christie and the most mysterious of all her detectives. His name is a word play on "Harlequin" which may be a clue to his personality. Mr. Quin helps his older friend Mr. Satterthwaite to solve crimes using his extraordinary skills and instincts. He appears in the short stories collection The Mysterious Mr Quin first published in 1930. Two short stories The Love Detectives and The Harlequin Tea Set (from Problem at Pollensa Bay and Other Stories) also feature Mr. Quin.
In her Autobiography Agatha Christie wrote that Mr. Quin and Mr. Satterthwaite (whom she called Quin's emissary) became her favourite characters. The reason was that she did not exploit them as much - she refused to make series of books about them, writing only when she felt like it. Here is how she described the protagonist: "Mr Quin was a figure who just entered into a story - a catalyst, no more - his mere presence affected human beings. There would be some little fact, some apparently irrelevant phrase, to point him out for what he was : a man shown in a harlequin-coloured light that fell on him through a glass window; a sudden appearance or disappearance."
