"Not so impatient," he said. "This is a friend."

Geoffrey asked no questions, though he was puzzled to know why the visitor did not enter the castle by the usual way. At Ralph's request he closed the window and drew the heavy curtains and the lamp was turned up again.

"My nephew," said Ralph. "A fine young fellow, and one that you and I can trust. Geoffrey, this is my old friend, Sergius Tchigorsky."

Geoffrey shook hands with Tchigorsky. To his intense surprise he saw the face of the stranger was disfigured in the same way as that of his uncle. Conscious that his gaze was somewhat rude he looked down. Tchigorsky smiled. Very little escaped him and to him the young man's mind was as clear as a brook.

"My appearance startles you," he said. "Some day you will learn how your uncle and myself came to be both disfigured in this terrible way. That secret will be disclosed when the horror that haunts this house is lifted."

"Will it ever be lifted, sir?" Geoffrey asked.

"We can do so at any time," Tchigorsky replied in his deep voice. "You may be surprised to hear that we can place our hand on the guilty party at a moment's notice and bring the offender to justice. Your eyes ask me why we do not do so instantly. We refrain, as the detectives refrain from arresting one or two of a big gang of swindlers, preferring to spread their nets till they have them all in their meshes. There are four people in this business, and we must take the lot of them, or there will be no peace for the house of Ravenspur. You follow me?"

"Perfectly," Geoffrey replied. "An enemy so marvelously clever must not be treated lightly. Do you propose to make the capture to-night?"

Ralph Ravenspur laughed. It was not a pleasant laugh and was mirthless. His scarred face was full of scornful amusement.

"Not to-night or to-morrow night, or for many nights," he said. "We have all the serpent wisdom of the Old World against us, the occult knowledge of the East allied to the slippery cunning that Western education gives. There will be many dangers before we have finished, and the worst of these dangers will fall upon you."
