47496    Long afterwards when I had fallen into a light sleep I heard a key turn somewhere in a lock, but I could not tell whence the sound came.

47497    What it all means I cannot guess, but there is some secret business going on in this house of gloom which sooner or later we shall get to the bottom of.

47498    I do not trouble you with my theories, for you asked me to furnish you only with facts.

47499    I have had a long talk with Sir Henry this morning, and we have made a plan of campaign founded upon my observations of last night.

47500    I will not speak about it just now, but it should make my next report interesting reading.

47501    CHAPTER 9 : The Light upon the Moor

47502    [Second report of Dr Watson] Baskerville Hall, Oct. 15th

47503    My Dear Holmes, If I was compelled to leave you without much news during the early days of my mission you must acknowledge that I am making up for lost time, and that events are now crowding thick and fast upon us.

47504    In my last report I ended upon my top note with Barrymore at the window, and now I have quite a budget already which will, unless I am much mistaken, considerably surprise you.

47505    Things have taken a turn which I could not have anticipated.

47506    In some ways they have within the last forty-eight hours become much clearer and in some ways they have become more complicated.

47507    But I will tell you all and you shall judge for yourself.

47508    Before breakfast on the morning following my adventure I went down the corridor and examined the room in which Barrymore had been on the night before.

47509    The western window through which he had stared so intently has, I noticed, one peculiarity above all other windows in the house - it commands the nearest outlook on to the moor.

47510    There is an opening between two trees which enables one from this point of view to look right down upon it, while from all the other windows it is only a distant glimpse which can be obtained.
