For a moment Mrs. Brooke stared at the girl in blank astonishment; then a look flashed from Margery's eyes into hers and she understood.

"Of whom are you speaking, girl?" asked Drumley sternly.

"O lor! I didn't see you, sir.--Why, who should I be speaking of but Muster Geril?"

"She refers to my husband, Mr. Gerald Brooke," remarked Clara.

The two men retired down the room a little way and talked together in low tones. "I ain't so sure that this is anything more than a clever dodge," said Drumley, "and that the gent we want isn't still somewhere about. However, you had better take Tomlinson with you and drive as hard as you can to Woodberry Station. The London train will be gone before you get there; but you can set the telegraph to work and make whatever inquiries you may think necessary. You've got the description?"--The sergeant nodded.--"Of course you've got to bear in mind that he may be disguised. Do the best you can, and then hurry back.--Send Simcox to me. I'll have the house thoroughly searched while you are away."

The man saluted and went; and presently Simcox appeared in his stead.

Drumley drew a little nearer Mrs. Brooke. "Without wishing in the least, ma'am, to doubt what you have told me about Mr. Brooke's departure," he said, "I consider it my duty to search the premises."

The piece of music Clara was holding fell to the ground. "To search the premises!" she exclaimed as she stooped to pick it up. She deliberately replaced the music on the piano before she spoke again. Then turning to Drumley with her most dignified air, she said: "You forget, sir, that you have not yet enlightened me as to the nature of your business at Beechley Towers."

"It is my painful duty to inform you, ma'am, that the Baron von Rosenberg was murdered this afternoon in his own grounds at Beaulieu."

"Murdered! The Baron von Rosenberg!" exclaimed both the ladies in a breath.
