"It would be useless for me to come here myself. By bad luck the man who pretends to be your nephew has seen me. If I were to come to stay here, he would suspect something. He would be on his guard." He pondered with closed eyes. "Miss Trimble," he exclaimed.

"I beg your pardon."

"You want Miss Trimble. She is the smartest worker in my office. This is precisely the type of case she could handle to perfection."

"A woman?" said Mrs. Pett doubtfully.

"A woman in a thousand," said Mr. Sturgis. "A woman in a million."

"But physically would a woman be—?"

"Miss Trimble knows more about jiu-jitsu than the Japanese professor who taught her. At one time she was a Strong Woman in small-time vaudeville. She is an expert revolver-shot. I am not worrying about Miss Trimble's capacity to do the work. I am only wondering in what capacity it would be best for her to enter the house. Have you a vacancy for a parlour-maid?"

"I could make one."

"Do so at once. Miss Trimble is at her best as a parlour-maid. She handled the Marling divorce case in that capacity. Have you a telephone in the room?"

Mrs. Pett opened the stuffed owl. The detective got in touch with his office.
