Castillo not to come with us." He took the others to the roof, where he walked to the edge and looked over the low parapet. A narrow, dark street divided Sarmiento's house from the next, but a lattice in a high wall was open, and Grahame imagined that he made out a man's head, which was, however, promptly withdrawn. "Once or twice a guest of mine has reached the[Pg 19] calle by a rope, but the President's friends take precautions to-night," Don Martin remarked.
