<h2> XVIII. WHAT AM I TO DO NOW </h2>
<p>Early morning saw Sweetwater peering into the depths of his closet. The
hole was hardly visible. This meant that the book he had pushed across it
from the other side had not been removed.</p>
<p>Greatly re-assured by the sight, he awaited his opportunity, and as soon
as a suitable one presented itself, prepared the hole for inspection by
breaking away its edges and begriming it well with plaster and old dirt.
This done, he left matters to arrange themselves; which they did, after
this manner.</p>
<p>Mr. Brotherson suddenly developed a great need of him, and it became a
common thing for him to spend the half and, sometimes, the whole of the
evening in the neighbouring room. This was just what he had worked for,
and his constant intercourse with the man whose secret he sought to
surprise should have borne fruit. But it did not. Nothing in the eager but
painstaking inventor showed a distracted mind or a heavily-burdened soul.
Indeed, he was so calm in all his ways, so precise and so self-contained,
that Sweetwater often wondered what had become of the fiery agitator and
eloquent propagandist of new and startling doctrines.</p>
<p>Then, he thought he understood the riddle. The model was reaching its
completion, and Brotherson's extreme interest in it and the confidence he
had in its success swallowed up all lesser emotions. Were the invention to
prove a failure—but there was small hope of this. The man was of too
well-poised a mind to over-estimate his work or miscalculate its place
among modern improvements. Soon he would reach the goal of his desires, be
praised, feted, made much of by the very people he now professedly
scorned. There was no thoroughfare for Sweetwater here. Another road must
be found; some secret, strange and unforeseen method of reaching a soul
inaccessible to all ordinary or even extraordinary impressions.</p>
<p>Would a night of thought reveal such a method? Night! the very word
brought inspiration. A man is not his full self at night. Secrets which,
under the ordinary circumstances of everyday life, lie too deep for
surprise, creep from their hiding-places in the dismal hours of universal
quiet, and lips which are dumb to the most subtle of questioners break
into strange and self-revealing mutterings when sleep lies heavy on ear
and eye and the forces of life and death are released to play with the
rudderless spirit.</p>
<p>It was in different words from these that Sweetwater reasoned, no doubt,
but his conclusions were the same, and as he continued to brood over them,
he saw a chance—a fool's chance, possibly, (but fools sometimes win
where wise men fail) of reaching those depths he still believed in,
notwithstanding his failure to sound them.</p>
<p>Addressing a letter to his friend in Twenty-ninth Street, he awaited reply
in the shape of a small package he had ordered sent to the corner
drug-store. When it came, he carried it home in a state of mingled hope
and misgiving. Was he about to cap his fortnight of disappointment by
another signal failure; end the matter by disclosing his hand; lose all,
or win all by an experiment as daring and possibly as fanciful as were his
continued suspicions of this seemingly upright and undoubtedly busy man?</p>
<p>He made no attempt to argue the question. The event called for the
exercise of the most dogged elements in his character and upon these he
must rely. He would make the effort he contemplated, simply because he was
minded to do so. That was all there was to it. But any one noting him well
that night, would have seen that he ate little and consulted his watch
continually. Sweetwater had not yet passed the line where work becomes
routine and the feelings remain totally under control.</p>
<p>Brotherson was unusually active and alert that evening. He was anxious to
fit one delicate bit of mechanism into another, and he was continually
interrupted by visitors. Some big event was on in the socialistic world,
and his presence was eagerly demanded by one brotherhood after another.
Sweetwater, posted at his loop-hole, heard the arguments advanced by each
separate spokesman, followed by Brotherson's unvarying reply: that when
his work was done and he had proved his right to approach them with a
message, they might look to hear from him again; but not before. His
patience was inexhaustible, but he showed himself relieved when the hour
grew too late for further interruption. He began to whistle—a token
that all was going well with him, and Sweetwater, who had come to
understand some of his moods, looked forward to an hour or two of
continuous work on Brotherson's part and of dreary and impatient waiting
on his own. But, as so many times before, he misread the man. Earlier than
common—much earlier, in fact, Mr. Brotherson laid down his tools and
gave himself up to a restless pacing of the floor. This was not usual with
him. Nor did he often indulge himself in playing on the piano as he did
to-night, beginning with a few heavenly strains and ending with a bang
that made the key-board jump. Certainly something was amiss in the quarter
where peace had hitherto reigned undisturbed. Had the depths begun to
heave, or were physical causes alone responsible for these unwonted
ebullitions of feeling?</p>
<p>The question was immaterial. Either would form an excellent preparation
for the coup planned by Sweetwater; and when, after another hour of
uncertainty, perfect silence greeted him from his neighbour's room, hope
had soared again on exultant wing, far above all former discouragements.</p>
<p>Mr. Brotherson's bed was in a remote corner from the loop-hole made by
Sweetwater; but in the stillness now pervading the whole building, the
latter could hear his even breathing very distinctly. He was in a deep
sleep.</p>
<p>The young detective's moment had come.</p>
<p>Taking from his breast a small box, he placed it on a shelf close against
the partition. An instant of quiet listening, then he touched a spring in
the side of the box and laid his ear, in haste, to his loop-hole.</p>
<p>A strain of well-known music broke softly, from the box and sent its
vibrations through the wall.</p>
<p>It was answered instantly by a stir within; then, as the noble air
continued, awakening memories of that fatal instant when it crashed
through the corridors of the Hotel Clermont, drowning Miss Challoner's cry
if not the sound of her fall, a word burst from the sleeping man's lips
which carried its own message to the listening detective.</p>
<p>It was Edith! Miss Challoner's first name, and the tone bespoke a shaken
soul.</p>
<p>Sweetwater, gasping with excitement, caught the box from the shelf and
silenced it. It had done its work and it was no part of Sweetwater's plan
to have this strain located, or even to be thought real. But its echo
still lingered in Brotherson's otherwise unconscious ears; for another
"Edith!" escaped his lips, followed by a smothered but forceful utterance
of these five words, "You know I promised you—"</p>
<p>Promised her what? He did not say. Would he have done so had the music
lasted a trifle longer? Would he yet complete his sentence? Sweetwater
trembled with eagerness and listened breathlessly for the next sound.
Brotherson was awake. He was tossing in his bed. Now he has leaped to the
floor. Sweetwater hears him groan, then comes another silence, broken at
last by the sound of his body falling back upon the bed and the troubled
ejaculation of "Good God!" wrung from lips no torture could have forced
into complaint under any daytime conditions.</p>
<p>Sweetwater continued to listen, but he had heard all, and after some few
minutes longer of fruitless waiting, he withdrew from his post. The
episode was over. He would hear no more that night.</p>
<p>Was he satisfied? Certainly the event, puerile as it might seem to some,
had opened up strange vistas to his aroused imagination. The words "Edith,
you know I promised you—" were in themselves provocative of strange
and doubtful conjectures. Had the sleeper under the influence of a strain
of music indissolubly associated with the death of Miss Challoner, been so
completely forced back into the circumstances and environment of that
moment that his mind had taken up and his lips repeated the thoughts with
which that moment of horror was charged? Sweetwater imagined the scene—saw
the figure of Brotherson hesitating at the top of the stairs—saw
hers advancing from the writing-room, with startled and uplifted hand—heard
the music—the crash of that great finale—and decided, without
hesitation, that the words he had just heard were indeed the thoughts of
that moment. "Edith, you know I promised you—" What had he promised?
What she received was death! Had this been in his mind? Would this have
been the termination of the sentence had he wakened less soon to
consciousness and caution?</p>
<p>Sweetwater dared to believe it. He was no nearer comprehending the mystery
it involved than he had been before, but he felt sure that he had been
given one true and positive glimpse into this harassed soul which showed
its deeply hidden secret to be both deadly and fearsome; and happy to have
won his way so far into the mystic labyrinth he had sworn to pierce, he
rested in happy unconsciousness till morning when—</p>
<p>Could it be? Was it he who was dreaming now, or was the event of the night
a mere farce of his own imagining? Mr. Brotherson was whistling in his
room, gaily and with ever increasing verve, and the tune which filled the
whole floor with music was the same grand finale from William Tell which
had seemed to work such magic in the night. As Sweetwater caught the
mellow but indifferent notes sounding from those lips of brass, he dragged
forth the music-box he held hidden in his coat pocket, and flinging it on
the floor stamped upon it.</p>
<p>"The man is too strong for me," he cried. "His heart is granite; he meets
my every move. What am I to do now?"</p>
