Afternoons, the suspect followed a more or less regular itinerary. He visited the manicure girl at the new barber shop; he patronized one or both of the moving picture places in the vicinity, but usually both, and then he went for a solitary walk through the park, and along toward dusk he returned to the boarding house, ate his supper and went to his room. He had no friends, apparently; certainly he had no callers. He received no letters and seemingly wrote none. Cassidy was convinced; he burned with eagerness to make the arrest without further delay. For this would be more than a feather in the Cassidy cap; it would be a whole war bonnet. "You kin stay in the background if you want to," he said. "Believe me, I'm perfectly willing to take all the credit for pulling off this pinch." As he said this they were passing along Broadway just above the subway terminal. The straggling line of new shops was on one side and the park stretched away on the other. Green was on the inner side of the pavement. Getting no answer to his suggestion, Mr. Cassidy started to repeat it. "I heard you," said Green, stopping now dead short, directly in front of the resplendent front of the Regal Motion Picture Palace. He contemplated with an apparently unwarranted interest the illuminated and lithographed announcements of the morrow's bill. "I'm perfectly willing to stay in the background," he said. "But--but I've just this very minute thought of a plan that ought to make us absolutely sure of our man--providing the plan works! Are you at all familiar with the tragedy of 'Macbeth'?" "I don't know as I am," admitted Mr. Cassidy honestly. "When did it happen and who done it?" Again his employer seemed not to hear him. "Let's go into this place," he said, turning in towards the hospitable portals of the Regal. "I want to have a business talk with the proprietor of this establishment, if he's in." The manager was in, and they had their talk; but after all it was money--which in New York speaks with such a clarion-loud and convincing voice--that did most of the talking. As soon as Judson Green had produced a bill-roll of august proportions, the proprietor, doubtful until that moment, showed himself to be a man open to all reasonable arguments. Moreover, he presently scented in this enterprise much free advertisement for his place. VI
