Without waiting for anything further, Field slipped out by the way he had come. Once in the road, he glanced back at the house, but the whole place seemed to be in pitchy darkness. There was nothing for it now but to make his way to the nearest police station, and get all the assistance possible. There was no trouble at the station across the Common, the mere mention of Field's name being sufficient. A few minutes later half a dozen constables in silent shoes were on their way to the scene of action. There was to be no fuss and bother; they decided to enter quietly and unostentatiously by the larder window, which was done without any noise whatever. Once the exits were guarded, there was no necessity for further concealment. But though the lights were turned up all over the house and the most careful search made, not a sign of human life could be seen. Everybody had vanished, as if the whole thing had been a dream. Field, standing in the hall and biting his nails, was fain to admit that he was beaten. How on earth had those people managed to efface themselves in that amazing manner? They had all apparently vanished off the face of the earth. And there was that bulky package too, that Field believed contained the body of Sir Charles. It was long past midnight before Field left the house, having taken precautions not to disturb anything, but even those precautions might have been in vain. For all he knew to the contrary, the place might be watched by its late occupants who were laughing in their sleeves. "No use staying here any longer, Macklin," he said disgustedly. "I shall have to go back on my tracks once more. Never do I take an amateur into my business plans again. But it looks as if he has paid for his indiscretion. Good night." It was late into the following afternoon before Field saw Beatrice Darryll again. When he did so, he had nothing to report save failure. Beatrice listened with the greatest interest to what had taken place the night before, but her interest gave place to grave anxiety when she heard what had been the result of Colonel Berrington's daring action. "Do you suppose that he is in real danger?" Beatrice asked.
