Green Eye had seen a great light as a result of the butler’s incautious revelations, and all his previous plans had been discarded. In their place a new one was growing—a plan that promised to set a record for daring, and to bring the detective nearer to professional shipwreck than he had been in all of his career.
The new plan did not involve an interview with Nick. On the contrary, it was built upon the fact that the detective was hundreds of miles away, buried in the woods.
Therefore, as may be guessed, Green Eye did not make use of the address the butler had given him. He was quite satisfied to have created the impression that he intended to communicate with Nick at once, and that the latter might return in the course of a day or two.
The following morning an individual climbed the stairs leading to one of Nick’s “halfway houses,” that particular one being on One Hundred and Twenty-fifth Street.
Nick Carter maintained a number of these places in different parts of the city, and in each of them he kept several complete changes of clothing and a supply of wigs, false mustaches, beards, make-up articles, and the like.
Their mission is perfectly obvious. Under ordinary circumstances, it was safe enough for the detective and his assistants to disguise themselves at home, and to return to their headquarters at their pleasure. When they were handling an unusually delicate case, however, or dealing with exceptionally clever lawbreakers, they found it necessary to take further precautions, and these so-called halfway houses then came in handy.
In other words, the secret bases of supplies—each of which had two exits—made it possible for them to leave and return to their headquarters openly, and without disguise, although the intervening hours might be devoted to the most relentless shadowing, carried on under all sorts of guises.
The man who climbed the stairs at the One Hundred and Twenty-fifth Street place, therefore, might easily have been Nick in the act of returning from some such expedition. He did not look in the least like the great detective, but that proved nothing, and his actions went far to indicate that he was Nick or one of the latter’s assistants.
He boldly approached the door of the room, the location of which did not seem to give him the slightest trouble, despite the fact that there was nothing on the door to guide him. He seemed to have some little difficulty in getting the door open, to be sure; but, after working at the lock for two or three minutes, he gained entrance.
