Adieu, and thank you, again and
   again, for all your kindness and consideration to me. "ARABELLA MARSH." Adam was surprised by this effusive epistle, but he determined to say
nothing of it to Sir Nathaniel until he should have thought it well over. When Adam met Sir Nathaniel at breakfast, he was glad that he had taken
time to turn things over in his mind. The result had been that not only
was he familiar with the facts in all their bearings, but he had already
so far differentiated them that he was able to arrange them in his own
mind according to their values. Breakfast had been a silent function, so
it did not interfere in any way with the process of thought. So soon as the door was closed, Sir Nathaniel began:

"I see, Adam, that something has occurred, and that you have much to tell
me." "That is so, sir. I suppose I had better begin by telling you all I
know--all that has happened since I left you yesterday?" Accordingly Adam gave him details of all that had happened during the
previous evening. He confined himself rigidly to the narration of
circumstances, taking care not to colour events by any comment of his
own, or any opinion of the meaning of things which he did not fully
understand. At first, Sir Nathaniel seemed disposed to ask questions,
but shortly gave this up when he recognised that the narration was
concise and self-explanatory. Thenceforth, he contented himself with
quick looks and glances, easily interpreted, or by some acquiescent
motions of his hands, when such could be convenient, to emphasise his
idea of the correctness of any inference. Until Adam ceased speaking,
having evidently come to an end of what he had to say with regard to this
section of his story, the elder man made no comment whatever. Even when
Adam took from his pocket Lady Arabella's letter, with the manifest
intention of reading it, he did not make any comment. Finally, when Adam
folded up the letter and put it, in its envelope, back in his pocket, as
an intimation that he had now quite finished, the old diplomatist
carefully made a few notes in his pocket-book. "Your narrative, my dear Adam, is altogether admirable. I think I may
now take it that we are both well versed in the actual facts, and that
our conference had better take the shape of a mutual exchange of ideas. Let us both ask questions as they may arise; and I do not doubt that we
shall arrive at some enlightening conclusions." "Will you kindly begin, sir? I do not doubt that, with your longer
experience, you will be able to dissipate some of the fog which envelops
certain of the things which we have to consider." "I hope so, my dear boy. For a beginning, then, let me say that Lady
Arabella's letter makes clear some things which she intended--and also
some things which she did not intend. But, before I begin to draw
deductions, let me ask you a few questions. Adam, are you heart-whole,
quite heart-whole, in the matter of Lady Arabella?" His companion answered at once, each looking the other straight in the
eyes during question and answer. "Lady Arabella, sir, is a charming woman, and I should have deemed it a
privilege to meet her--to talk to her--even--since I am in the
confessional--to flirt a little with her. But if you mean to ask if my
affections are in any way engaged, I can emphatically answer 'No!' --as
indeed you will understand when presently I give you the reason. Apart
from that, there are the unpleasant details we discussed the other day." "Could you--would you mind giving me the reason now? It will help us to
understand what is before us, in the way of difficulty." "Certainly, sir. My reason, on which I can fully depend, is that I love
another woman!" "That clinches it. May I offer my good wishes, and, I hope, my
congratulations?" "I am proud of your good wishes, sir, and I thank you for them. But it
is too soon for congratulations--the lady does not even know my hopes
yet. Indeed, I hardly knew them myself, as definite, till this moment." "I take it then, Adam, that at the right time I may be allowed to know
who the lady is?" Adam laughed a low, sweet laugh, such as ripples from a happy heart. "There need not be an hour's, a minute's delay. I shall be glad to share
my secret with you, sir. The lady, sir, whom I am so happy as to love,
and in whom my dreams of life-long happiness are centred, is Mimi
Watford!" "Then, my dear Adam, I need not wait to offer congratulations. She is
indeed a very charming young lady. I do not think I ever saw a girl who
united in such perfection the qualities of strength of character and
sweetness of disposition. With all my heart, I congratulate you. Then I
may take it that my question as to your heart-wholeness is answered in
the affirmative?" "Yes; and now, sir, may I ask in turn why the question?" "Certainly! I asked because it seems to me that we are coming to a point
where my questions might be painful to you." "It is not merely that I love Mimi, but I have reason to look on Lady
Arabella as her enemy," Adam continued. "Her enemy?" "Yes. A rank and unscrupulous enemy who is bent on her destruction." Sir Nathaniel went to the door, looked outside it and returned, locking
it carefully behind him. CHAPTER XX--METABOLISM


"Am I looking grave?" asked Sir Nathaniel inconsequently when he
re-entered the room. "You certainly are, sir." "We little thought when first we met that we should be drawn into such a
vortex. Already we are mixed up in robbery, and probably murder, but--a
thousand times worse than all the crimes in the calendar--in an affair of
ghastly mystery which has no bottom and no end--with forces of the most
unnerving kind, which had their origin in an age when the world was
different from the world which we know. We are going back to the origin
of superstition--to an age when dragons tore each other in their slime. We must fear nothing--no conclusion, however improbable, almost
impossible it may be. Life and death is hanging on our judgment, not
only for ourselves, but for others whom we love. Remember, I count on
you as I hope you count on me." "I do, with all confidence." "Then," said Sir Nathaniel, "let us think justly and boldly and fear
nothing, however terrifying it may seem. I suppose I am to take as exact
in every detail your account of all the strange things which happened
whilst you were in Diana's Grove?" "So far as I know, yes. Of course I may be mistaken in recollection of
some detail or another, but I am certain that in the main what I have
said is correct." "You feel sure that you saw Lady Arabella seize the negro round the neck,
and drag him down with her into the hole?" "Absolutely certain, sir, otherwise I should have gone to her
assistance." "We have, then, an account of what happened from an eye-witness whom we
trust--that is yourself. We have also another account, written by Lady
Arabella under her own hand. These two accounts do not agree. Therefore
we must take it that one of the two is lying." "Apparently, sir."
