'From a View to a Kill' (1960) by Ian Fleming

Bond investigates the murder of a motorcycle dispatch-rider and the theft of his top-secret documents by a motorcycle-riding assassin. The dispatch-rider was en-route from SHAPE, the Supreme Headquarters Allied Powers Europe – at that time located in Versailles – to his base, Station F, in Saint-Germain, France.

Given that Bond is already in Paris, his superior, M, sends him to assist in the investigation in any way he can. Bond disguises himself as a dispatch-rider and follows the same route to Station F as the previous rider. As expected, the assassin attempts to kill Bond. Bond, however, is ready, and kills the assassin. He then uncovers the assassin's hidden base of operations.
