The curtain had risen on the fourth act, and Patty squeezed herself into the somewhat close quarters behind the balcony. There was fortunately—or rather unfortunately—a window in the rear of the building at this point, and Patty opened it and perched herself at one end of the sill, with the lamp-chimney ready for use at the other end. The crash was not due for some time, and Patty, having lately elected astronomy, whiled away the interval by examining the stars.

On the stage matters were approaching a climax. Lord Bromley was making an excellent lover, as was proved by the fact that the audience was taking him seriously instead of laughing through the love scenes as usual.

"Cynthia," he implored, "say that you will be mine, and I will brave all for your sake. I will follow you to the ends of the earth." He gazed tenderly into her eyes, and waited for the crash. A silence as of the tomb prevailed, and he continued to gaze tenderly, while a grin rapidly spread over the audience.

"Hang Patty!" he murmured savagely. "Might have known she'd do something like this.—What was that? Did you hear a noise?" he asked aloud.

"No," said Cynthia, truthfully; "I did not hear anything."

"Pretend you did," he whispered, and they continued to improvise. After some five minutes of hopeless floundering, the prompter got them back on the track again, and the act proceeded, with the audience happily unaware that anything was missing.

Ten minutes later Lord Bromley was declaiming: "Cynthia, let us flee this place. Its dark rooms haunt me; its silence oppresses me—" And the crash came.

For the first moment the audience was too startled to notice that the actors were also taken by surprise. Then Lord Bromley, who was getting used to emergencies, pulled himself together and ejaculated, "Hark! What was that sound?"

"I think it was a crash," said Cynthia.

He grasped her hand and ran back toward the balcony. "Give us our lines," he said to the prompter, as he went past.
