“Who’s that?”

“It is I—Violet Christie. Is that you, Laurence?”

“Hush! All right!” he whispered back. “Let me in.”

He got in softly through the window, and, rather to my alarm, a middle-aged man in plain clothes, also with a lantern, followed him. Laurence himself looked more alarming than any thief. His face was ghastly white with fatigue, and dirtier than ever through long watching in the fog. He listened for a minute to the violin, then said quickly, but still in a low voice—

“Who is that playing?”

“Mr. Rayner,” I answered.

He turned sharply to the other man, who nodded as if to say it was just what he had expected.

“How long has he been playing?” asked Laurence.

“Ever since half-past seven.”

He turned to the other man again.
