Nancy never lacks money, and in later volumes of the series often travels to faraway locations, such as France in "The Mystery of the 99 Steps" (1966), Nairobi in "The Spider Sapphire Mystery" (1968), Istanbul in “The Mysterious Mannequin” (1970), Austria in "Captive Witness" (1981), Japan in "The Runaway Bride" (1994), Costa Rica in "Scarlet Macaw Scandal" (2004), and Alaska in "Curse of The Arctic Star" (2013). Nancy is also able to travel freely about the United States, thanks in part to her car, which is a blue roadster in the original series and a blue convertible in the later books. Despite the trouble and presumed expense to which she goes to solve mysteries, Nancy never accepts monetary compensation; however, by implication, her expenses are often paid by a client of her father's, as part of the costs of solving one of his cases.
