"I consider it inadvisable to make any arrest at the present stage of my investigations," he said, with cold official dignity.

"Do you think you know who did it?" asked the girl.

"It is my business to find out," replied the inspector, in a voice that indicated confidence in his ability to perform the task.

The girl was too unsophisticated to follow the subtle workings of official pride. "The papers call it a mysterious crime. Do you think it is mysterious?"

"There are certainly some mysterious features about it," said the inspector. "But I do not regard them as insoluble. Nothing is insoluble," he added, in a sententious tone.

"If there are mysteries to be solved you ought to have help," said the young lady.

She glanced at Mrs. Hewson significantly, and then proceeded to explain to Inspector Chippenfield what she meant.

"I have asked Mr. Crewe, the celebrated detective, to assist you. Of course you know Mr. Crewe—everybody does. I know you are a very clever man at your profession, but in a thing of this kind two clever men are better than one. I hope you will not mind—there is no reflection whatever on your ability. In fact, I have the utmost confidence in you. But it is due to my father's memory to do all that is possible to get to the bottom of this dreadful crime. If money is needed it will be forthcoming. That applies to you no less than to Mr. Crewe. But I hope you will be able to carry out your investigations amicably together, and that you will be willing to assist one another. You will lose nothing by doing so. I trust you will place at Mr. Crewe's disposal all the facilities that are available to you as an officer of the police."

This statement was so clear that Inspector Chippenfield had no choice but to face the conclusion that Miss Fewbanks had more faith in the abilities of a private detective to unravel the mystery than she had in the resources of Scotland Yard. He would have liked to have told the young lady what he thought of her for interfering with his work, and he determined to avail himself of the right opportunity to do so if it came along. But the statement that money was not to be spared had a soothing influence on his feelings. Of course, officers of Scotland Yard were not allowed to take gratuities however substantial they might be, but there were material ways of expressing gratitude which were outside the regulations of the department.

"I shall be very pleased to give Mr. Crewe any assistance he wants," said
Inspector Chippenfield, bowing stiffly.
