Author Lee Child has written a series of fictional novels which feature Jack Reacher, a former Major in the United States Army Military Police Corps.
Since leaving the Army, Reacher has been a drifter. He wanders throughout the U.S. because he was accustomed to being told where to go, when to go and what to do for every day of his life from military childhood to military adulthood. He also felt he never got to know his own country, having spent much of his youth living overseas on military bases and at West Point. He usually travels by hitchhiking or bus. As a drifter, the only possessions he carries are money, a foldable toothbrush and, after 9/11, an expired passport and an ATM debit card.
He wears his clothing for 2–3 days before discarding it, usually purchasing new clothing cheaply from chain outlets. He has no steady income and lives on savings in his bank account and part-time jobs. Since he has no fixed address, Reacher often eats in diners and other inexpensive restaurants.
