The Battle of Basinghall Street by E. Phillips Oppenheim

At about ten minutes to six that evening a comfortable private car of the ordinary limousine type was brought to a standstill before a small garage in the neighbourhood of Tottenham. A tall, heavily built man, so closely muffled up that he would have been unrecognisable even to his friends and wearing thick motoring glasses, descended and, after a word or two with the chauffeur, who pointed to a car of somewhat similar appearance which was apparently being prepared for use, entered the place. An employee of the garage, who had been in the act of drawing on a heavy driving coat, came down some steps from the office to meet him.

"Are you Mr. Bostock?" the visitor enquired.
