"This much. Your cousin told Sir Simon about the use she made of the Red Window--your cousin Miss Randolph, I mean--and when she was at the Curtain Theatre with Beryl, I believe he put the lamp in the window to attract you." "Had the lamp a red glass?" "No. But a red bandana handkerchief such as Sir Simon used might have been stretched across the window. I daresay he did it." "But he didn't know that I knew the house," objected Gore. "True enough, unless"--here Durham hesitated--"unless it was your grandfather who sent Jerry Moon to lure you to the square." "No! Judas--as Conniston calls him--is Beryl's tool. I would rather believe that Beryl placed the red handkerchief across the window." "There was no handkerchief found," said Durham. "Mrs. Webber saw the red light, yet when Beryl went out to look for it he could see none, neither could she. What do you infer from that, Bernard?" "That the handkerchief must have been removed in the meanwhile by Beryl. No," Bernard recollected, "not by Beryl; Mrs. Gilroy prevented him going up the stairs. But Lucy, the cook and Jane Riordan went up;--one of them must have removed the handkerchief. I tell you what, Mark," added Bernard, thoughtfully, "it was Lucy who placed the lamp by the window and stretched the handkerchief across it." "We don't know that a handkerchief was so stretched," said Durham. "It must have been to cause the red light," insisted Gore. "Lucy always had the idea of the Red Window. She was then friendly with Beryl, and she might have made use of Jerry Moon to bring me to the square in the hope that, seeing the red light, I might venture into the house and interview my grandfather." "Well," said Durham, rising, "we will ask Miss Randolph. Also we can question this young Judas, who is now with Miss Plantagenet." Bernard did not answer. With his head on his hand he was pondering deeply. "One thing I can't understand," he said, after a pause: "Why do you connect my Uncle Guiseppe with the Red Window?" "I don't, but with the Red Lamp. In this especial instance, for lack of red glass a lamp was used. It was not the ordinary lighting of the room, remember. Now, Tolomeo must have been in the room, and he must have seen the lamp to make use of such an expression." "So you believe he was with Sir Simon when Lucy and Beryl were at the theatre?" "Yes," said Durham, looking directly at Gore, "and Tolomeo is Italian." Bernard jumped up nervously. "Do you mean to hint that Tolomeo may have strangled my grandfather?" "Yes, I do. Tolomeo may have come to see him--indeed, he must have done so to make use of such an expression as the 'Red Lamp.' The two quarrelled, and perhaps your uncle, losing his temper----" "No, no! I can't believe that," said Gore, walking anxiously to and fro. "Tolomeo is wild but not wicked."
