Mr. Martin had long ago abandoned cigarettes for cigars, but he felt a momentary impulse to go in and renew the old acquaintance. Sam Copperdock had been a good customer of his, he remembered. Many a bottle of whiskey had he sold him. But on second thoughts he refrained. Perhaps it would be just as well, in the light of what might happen during the next half hour or so, that his visit to Praed Street remained unsuspected.
