"I believe," she said at last, "that you are a private detective. I come to ask for your help in a matter of some difficulty. Some papers of the utmost importance, not only to me but to others, are in the possession of a person who intends to profit by the information contained in them to do myself and my friends an irreparable injury. You can imagine how anxious we are to obtain them from him."
"Do I understand that this person threatens you with blackmail?" asked Gimblet.
The lady hesitated.
"Something of the kind," she replied after a moment's pause.
"And you have so far given in to his demands?"
"Yes," admitted the visitor. "Up till now we have been obliged to submit."
"Has he proposed any terms on which he will be willing to return you the papers?" asked the detective.
"No," she replied. "I do not think any terms are possible."
"How did this person obtain possession of the papers?" Gimblet asked after a moment. "Did he steal them from you?"
"No."
"From your friends?"
She hesitated.
"No--not exactly."
"From whom, then?" asked Gimblet in surprise. "I suppose they were yours in the first place?"
"He has always had them," she said reluctantly; "but they must not remain his."
"Do you mean they are his own?" exclaimed Gimblet. "In that case it is you who propose to steal them!"
"No," replied the strange lady calmly. "I want you to do that."
"I'm sorry," said Gimblet; "that is not in my line of business. I'm afraid you made a mistake in coming to me. I cannot undertake your commission."
"Money is no object; we shall ask you to name your own price," urged his visitor.
But the detective shook his head.
"It is a matter of life and death," she said, and her voice betrayed an agitation which could not have been inferred from her motionless shrouded figure. "If you refuse to help me, not one life, but many, will be endangered."
"If you can offer me convincing proof of that," said Gimblet, "I might feel it my duty to help you. I don't say I should, but I might. In any case I can do nothing unless you are perfectly open and frank with me. Expect no assistance from me unless you tell me everything, and then only if I think it right to give it."
