My Dear Mr. Holmes: I should be very glad of your immediate assistance in what promises to be a most remarkable case. It is something quite in your line. Except for releasing the lady I will see that everything is kept exactly as I have found it, but I beg you not to lose an instant, as it is difficult to leave Sir Eustace there. Yours faithfully, STANLEY HOPKINS 'Hopkins has called me in seven times, and on each occasion his summons has been entirely justified, ' said Holmes. 'I fancy that every one of his cases has found its way into your collection, and I must admit, Watson, that you have some power of selection, which atones for much which I deplore in your narratives. Your fatal habit of looking at everything from the point of view of a story instead of as a scientific exercise has ruined what might have been an instructive and even classical series of demonstrations. You slur over work of the utmost finesse and delicacy, in order to dwell upon sensational details which may excite, but cannot possibly instruct, the reader.
