Bernard looked up alertly, and his brow grew dark. "How do you make that out?"
"Well," said Durham, after a pause, "I questioned Jane Riordan again about the possibility of there having been a red light visible!"
"There was," interrupted Gore, decisively. "I saw it myself."
"And Mrs. Webber saw it, although afterwards it disappeared. Well, Jane told me that there was a lamp on the table in front of the window. She saw it when she went up with the cook and Miss Randolph."
"I remember. I was in the grip of the policeman then," said Gore.
"Well, it is strange, seeing that the apartment was lighted by electricity, that a lamp should have stood in front of the window."
"What do you infer?" asked Bernard, doubtfully and uneasily.
"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."
