"Well, we're bound to take you on your own terms," said the inspector; "but when it comes to telling us to abandon the case- why in the name of goodness should we abandon the case?"
"For the simple reason, my dear Mr. Mac, that you have not got the first idea what it is that you are investigating."
"We are investigating the murder of Mr. John Douglas of Birlstone Manor."
"Yes, yes, so you are. But don't trouble to trace the mysterious gentleman upon the bicycle. I assure you that it won't help you."
"Then what do you suggest that we do?"
"I will tell you exactly what to do, if you will do it."
"Well, I'm bound to say I've always found you had reason behind all your queer ways. I'll do what you advise."
"And you, Mr. White Mason?"
The country detective looked helplessly from one to the other.
Holmes and his methods were new to him. "Well, if it is good enough for the inspector, it is good enough for me," he said at last.
"Capital!" said Holmes. "Well, then, I should recommend a nice, cheery country walk for both of you. They tell me that the views from Birlstone Ridge over the Weald are very remarkable. No doubt lunch could be got at some suitable hostelry, though my ignorance of the country prevents me from recommending one. In the evening, tired but happy-"
"Man, this is getting past a joke!" cried MacDonald, rising angrily from his cheir.
"Well, well, spend the day as you like," said Holmes, patting him cheerfully upon the shoulder. "Do what you like and go where you will, but meet me here before dusk without fail- without fail, Mr. Mac."
"That sounds more like sanity."
"All of it was excellent advice; but I don't insist, so long as you are here when I need you. But now, before we part, I want you to write a note to Mr. Barker."
"I'll dictate it, if you like. Ready?
"Dear Sir:
"It has struck me that it is our duty to drain the moat, in the hope that we may find some-"
"It's impossible," said the inspector. "I've made inquiry."
"Tut, tut! My dear sir, please do what I ask you."
"Well, go on."
"-in the hope that we may find something which may bear upon our investigation. I have made arrangements, and the workmen will be at work early to-morrow morning diverting the stream-"
"Impossible!"
"-diverting the stream; so I thought it best to explain matters beforehand.
Now sign that, and send it by hand about four o'clock. At that hour we shall meet again in this room. Until then we may each do what we like; for I can assure you that this inquiry has come to a definite pause."
Evening was drawing in when we reassembled. Holmes was very serious in his manner, myself curious, and the detectives obviously critical and annoyed.
"Well, gentlemen," said my friend gravely, "I am asking you now to put everything to the test with me, and you will judge for yourselves whether the observations I have made justify the conclusions to which I have come. It is a chill evening, and I do not know how long our expedition may last; so I beg that you will wear your warmest coats. It is of the first importance that we should be in our places before it grows dark; so with your permission we shall get started at once."
We passed along the outer bounds of the Manor House park until we came to a place where there was a gap in the rails which fenced it.
Through this we slipped, and then in the gathering gloom we followed Holmes until we had reached a shrubbery which lies nearly opposite to the main door and the drawbridge. The latter had not been raised.
Holmes crouched down behind the screen of laurels, and we all three followed his example.
"Well, what are we to do now?" asked MacDonald with some gruffness.
"Possess our souls in patience and make as little noise as possible," Holmes answered.
"What are we here for at all? I really think that you might treat us with more frankness."
Holmes laughed. "Watson insists that I am the dramatist in real life," said he. "Some touch of the artist wells up within me, and calls insistently for a well staged performance. Surely our profession, Mr. Mac, would be a drab and sordid one if we did not sometimes set the scene so as to glorify our results. The blunt accusation, the brutal tap upon the shoulder- what can one make of such a denouement? But the quick inference, the subtle trap, the clever forecast of coming events, the triumphant vindication of bold theories- are these not the pride and the justification of our life's work? At the present moment you thrill with the glamour of the situation and the anticipation of the hunt. Where would be that thrill if I had been as definite as a timetable? I only ask a little patience, Mr. Mac, and all will be clear to you."
"Well, I hope the pride and justification and the rest of it will come before we all get our death of cold," said the London detective with comic resignation.
We all had good reason to join in the aspiration; for our vigil was a long and bitter one. Slowly the shadows darkened over the long, sombre face of the old house. A cold, damp reek from the moat chilled us to the bones and set our teeth chattering. There was a single lamp over the gateway and a steady globe of light in the fatal study. Everything else was dark and still.
"How long is this to last?" asked the inspector finally. "And what is it we are watching for?"
"I have no more notion than you how long it is to last," Holmes answered with some asperity. "If criminals would always schedule their movements like railway trains, it would certainly be more convenient for all of us. As to what it is we-- Well, that's what we are watching for!"
