OF course every one has heard of the Motor Pirate. No one indeed could help doing so unless he or she, as the case may be, happened to be in some part of the world where newspapers never penetrate; since for months his doings were the theme of every gossip in the country, and his exploits have filled columns of every newspaper from the moment of his first appearance until the day when the reign of terror he had inaugurated upon the roads ended as suddenly and as sensationally as it had begun. Who the owner of the pirate car was? Whence he came? Whither he went? These are questions which have exercised minds innumerable; but though there have been nearly as many theories propounded as there were brains at work propounding them, so far no informed account of the man or his methods has been made public.
