When I say I am called Valmont, the name will convey no impression to the reader, one way or another. My occupation is that of private detective in London, but if you ask any policeman in Paris who Valmont was he will likely be able to tell you, unless he is a recent recruit. If you ask him where Valmont is now, he may not know, yet I have a good deal to do with the Parisian police. For a period of seven years I was chief detective to the Government of France, and if I am unable to prove myself a great crime hunter, it is because the record of my career is in the secret archives of Paris.
