Emile
Emile is a Captain from le Gendarmerie de Quirm, or the Quirmian equivalent of the Ankh-Morpork City Watch.
As part of an exchange program with the Watch (fueled by the high demand for Sam Vimes trained officers), he was sent to Ankh-Morpork and Acting Captain Haddock was sent to replace him in Quirm sometime before the beginning of Snuff. This worked out fairly well for the Ankh-Morpork Watch, because he revolutionised the in-house catering for the Watch, delivering palatable canteen food with a large side-serving of avec.
