DEAR SIR—Having now been favored with the necessary instructions from Sergeant Bulmer, I beg to remind you of certain directions which I have received relating to the report of my future proceedings which I am to prepare for examination at headquarters.

The object of my writing, and of your examining what I have written before you send it to the higher authorities, is, I am informed, to give me, as an untried hand, the benefit of your advice in case I want it (which I venture to think I shall not) at any stage of my proceedings. As the extraordinary circumstances of the case on which I am now engaged make it impossible for me to absent myself from the place where the robbery was committed until I have made some progress toward discovering the thief, I am necessarily precluded from consulting you personally. Hence the necessity of my writing down the various details, which might perhaps be better communicated by word of mouth. This, if I am not mistaken, is the position in which we are now placed. I state my own impressions on the subject in writing, in order that we may clearly understand each other at the outset; and have the honor to remain your obedient servant,

MATTHEW SHARPIN. FROM CHIEF INSPECTOR THEAKSTONE TO MR. MATTHEW SHARPIN.

London, 5th July, 18—.

SIR—You have begun by wasting time, ink, and paper. We both of us perfectly well knew the position we stood in toward each other when I sent you with my letter to Sergeant Bulmer. There was not the least need to repeat it in writing. Be so good as to employ your pen in future on the business actually in hand.

You have now three separate matters on which to write me. First, you have to draw up a statement of your instructions received from Sergeant Bulmer, in order to show us that nothing has escaped your memory, and that you are thoroughly acquainted with all the circumstances of the case which has been intrusted to you. Secondly, you are to inform me what it is you propose to do. Thirdly, you are to report every inch of your progress (if you make any) from day to day, and, if need be, from hour to hour as well. This is your duty. As to what my duty may be, when I want you to remind me of it, I will write and tell you so. In the meantime, I remain yours,

FRANCIS THEAKSTONE. FROM MR. MATTHEW SHARPIN TO CHIEF INSPECTOR THEAKSTONE.

London, 6th July, 18—.

SIR—You are rather an elderly person, and as such, naturally inclined to be a little jealous of men like me, who are in the prime of their lives and their faculties. Under these circumstances, it is my duty to be considerate toward you, and not to bear too hardly on your small failings. I decline, therefore, altogether to take offense at the tone of your letter; I give you the full benefit of the natural generosity of my nature; I sponge the very existence of your surly communication out of my memory—in short, Chief Inspector Theakstone, I forgive you, and proceed to business.

My first duty is to draw up a full statement of the instructions I have received from Sergeant Bulmer. Here they are at your service, according to my version of them.
