Inspector Gabriel Hanaud is a fictional French detective depicted in a series of five novels, one novella and one short story by the British writer A. E. W. Mason.
[5] He was to be a genial and friendly soul ready, "as the French detective does", to trust his flair or intuition and to take the risk of acting upon it.
Hanaud made his first appearance in the 1910 novel At the Villa Rose set in the south of France.
Hanaud has been portrayed on screen several times – with adaptations of At the Villa Rose and The House of the Arrow.
He has been seen as one of a number of influences on the creation of Agatha Christie's Belgian detective Hercule Poirot.
