Mrs. Gilroy laughed again. "I am coming to that. You will be much surprised when I tell you all. Bernard was in town as a soldier; Beryl got Michael to masquerade. I never knew it was my own son who courted Jane Riordan. Had I known, I should have put a stop to the business. I really thought from the description given, that Jane's lover was Bernard. I wanted Sir Simon, whom I told, to throw over Bernard and let my son have the property. He would have done so, but that Michael had forged a check----" "I know about that also." "Very good. We will pass that," said the woman. "Well, Sir Simon was angry. I saw there was no chance for my boy, and cast about how else to get the money for him. Beryl informed me that he intended by means of the Red Window and Jerry to lure Bernard to the Square, in the hope that when he saw the red light he would come up and have a quarrel with his grandfather." "What about?" asked Durham. "About Bernard's supposed courting of the housemaid. That was why Beryl employed my son to masquerade. He knew that Sir Simon was a proud man, and would not readily forgive such a thing. He knew Sir Simon was regretting his quarrel with Bernard, and wished to give it renewed life. Well, then, Beryl arranged to go to the theatre. He said he would come round after ten or near eleven to see if the old man had quarrelled with Bernard. He hoped that he would be able to get the order to turn Bernard out. He did not know, though, at what time Bernard would arrive. But when he did, I was to open the door to him." "Jerry's whistle was to be the signal," said the lawyer. "Yes. Then I was to show Bernard up, and the quarrel would then take place." "Beryl did not really intend murder, then?" "Mr. Durham, you will harp on that," said Mrs. Gilroy, impatiently. "Wait till I speak out. You see how matters were arranged for that night. Miss Randolph and Beryl went to the theatre so that they should not be mixed up in the quarrel." "But Miss Randolph knew nothing?" "Of course not. Beryl knew she was friendly to Bernard, and wished her out of the way. For that reason, he took her to the theatre. I then suggested to Sir Simon that probably Bernard knew of the house from you, and might come back. Sir Simon had sent for him to the kitchen, but my son, being afraid, ran away. Sir Simon laughed at the idea of the red lamp, but he did not forbid my arranging it. I got a lamp and placed it before the window. Then I placed across the window a red bandana of Sir Simon's. From the outside the signal could be plainly seen." "What happened next?" asked Durham, while the typewriter clicked in a most cheerful manner. "Various things," retorted Mrs. Gilroy, "and not those you expect to hear. I sat downstairs, waiting and working. Sir Simon was in the room with the red light showing through the window. The trap was laid. It only remained for Jerry to bring Bernard to fall into it. Shortly before ten an Italian called." "Bernard's uncle, Signor Tolomeo?"
