The next morning Maitland walked in upon us. He had found both of Mr. Darrow's former servants and satisfied himself that they were in San Francisco on the night of the murder. So that ended my Chinese clue. While Alice and Gwen were discussing the matter, I took occasion to draw Maitland aside, and told him of Gwen's appointment to take charge of the Cleopatra night, and how necessary it was to her health that she should be aroused from her torpor. It doesn't take long for Maitland to see a thing, and before I had whispered a dozen sentences he had completely grasped the situation. He crossed the room, drew a chair up beside Gwen, and sat down. "Miss Darrow," he began, "I am afraid you will have a poor opinion of me as a detective. This is the second time I have failed. I feel that I should remind you again of our compact, at least, that part of it which permits you to dispense with my services whenever you shall see fit to do so, and, at the same time, to relieve you from your obligation to let me order your actions. I tell you frankly it will be necessary for you to discharge me, if you would be rid of me, for, unless you do so, or I find the assassin, I shall never cease my search so long as I have the strength and means to conduct it. What do you say? Have I not proved my uselessness?" This was said in a tentative, half-jesting tone. Gwen answered it very seriously.

I do not know much of the abilities of Messrs. Osborne and Allen, but I understand that M. Godin has the reputation of being the cleverest detective in America. I cannot learn that he has made any progress whatsoever in the solution of this terrible mystery. I do not feel, therefore, that you have any right to reproach yourself. Such hope as I have that my father's murderer may ever be brought to justice rests in your efforts; else I should feel bound to relieve you of a task, which, though self-imposed, is, none the less, onerous and ill-paid. Do not consider me altogether selfish if I ask that you still continue the search, and that I--that I still be held to my covenant. I am aware that I can never fully repay the kindness I am asking of you, but--"
