<h3> CHAPTER XIII </h3>
<h3> THE WHITE BEAM </h3>
<p>That night the deviltry began. Mr. Mostyn found himself wholly
unable to sleep. Many relics have curious histories, and the
experienced archaeologist becomes callous to that uncanniness which
seems to attach to some gruesome curios. But the slipper of the
Prophet was different. No mere ghostly menace threatened its
holders; an avenging scimitar followed those who came in contact
with it; gruesome tragedies, mutilations, murders, had marked its
progress throughout.</p>
<p>The night was still—as still as a London night can be; for there
is always a vague murmuring in the metropolis as though the
sleeping city breathed gently and sometimes stirred in its sleep.</p>
<p>Then, distinct amid these usual nocturnal noises, rose another,
unaccountable sound, a muffled crash followed by a musical tinkling.</p>
<p>Mostyn sprang up in bed, drew on a dressing-gown, and took from the
small safe at his bed-head the Museum keys and a loaded revolver.
A somewhat dishevelled figure, pale and wild-eyed, he made his way
through the private door and into the ghostly precincts of the
Museum. He did not hesitate, but ascended the stairs and unlocked
the door of the Assyrian gallery.</p>
<p>Along its ghostly aisles he passed, and before the door which gave
admittance to the Burton Room paused, fumbling a moment for the
key.</p>
<p>Inside the room something was moving!</p>
<p>Mostyn was keenly alarmed; he knew that he must enter at once or
never. He inserted the key in the lock, swung open the heavy door,
stepped through and closed it behind him. He was a man of
tremendous moral courage, for now,—alone in the apartment which
harboured the uncanny relic, alone in the discharge of his duty,
he stood with his back to the door trembling slightly, but with
the idea of retreat finding no place in his mind.</p>
<p>One side of the room lay in blackest darkness; through the
furthermost window of the other a faint yellowed luminance (the
moonlight through the blind) spread upon the polished parquet
flooring. But that which held the curator spell-bound—that which
momentarily quickened into life the latent superstition, common to
all mankind, was a beam of cold light which poured its effulgence
fully upon the case containing the Prophet's slipper! Where the
other exhibits lay either in utter darkness or semi-darkness this
one it seemed was supernaturally picked out by this lunar
searchlight!</p>
<p>It was ghostly-unnerving; but, the first dread of it passed, Mostyn
recalled how during the day a hole inexplicably had been cut in
that blind; he recalled that it had not been mended, but that the
damaged blind had merely been rolled up again.</p>
<p>And as a dawning perception of the truth came to him, as falteringly
he advanced a step toward the mystic beam, he saw that one side of
the case had been shattered—he saw the broken glass upon the floor;
and in the dense shadow behind and under the beam of light, vaguely
he saw a dull red object.</p>
<p>It moved—it seemed to live! It moved away from the case and in
the direction of the eastern windows.</p>
<p>"My God!" whispered Mostyn; "it's the Prophet's slipper!"</p>
<p>And wildly, blindly, he fired down the room. Later he knew that he
had fired in panic, for nothing human was or could be in the place;
yet his shot was not without effect. In the instant of its flash,
something struck sharply against the dimly seen blind of one of the
east windows; he heard the crash of broken glass.</p>
<p>He leapt to the switch and flooded the room with light. A fear of
what it might hold possessed him, and he turned instantly.</p>
<p>Hard by the fragments of broken glass upon the floor and midway
between the case and the first easterly window lay the slipper. A
bell was ringing somewhere. His shot probably had aroused the
attention of the policeman. Someone was clamouring upon the door
of the Museum, too. Mostyn raced forward and raised the blind—that
toward which the slipper had seemed to move.</p>
<p>The lower pane of the window was smashed. Blood was trickling down
upon the floor from the jagged edges of the glass.</p>
<p>"Hullo there! Open the door! Open the door!"</p>
<p>Bells were going all over the place now; sounds of running footsteps
came from below; but Mostyn stood staring at the broken window and
at the solid iron bars which protected it without, which were intact,
substantial—which showed him that nothing human could possibly
have entered.</p>
<p>Yet the case was shattered, the holy slipper lay close beside him
upon the floor, and from the broken window-pane blood was
falling—drip-drip-drip...</p>
<p>That was the story as I heard it half an hour later. For Inspector
Bristol, apprised of the happening, was promptly on the scene; and
knowing how keen was my interest in the matter, he rang me up
immediately. I arrived soon after Bristol and found a perplexed
group surrounding the uncanny slipper of the Prophet. No one had
dared to touch it; the dread vengeance of Hassan of Aleppo would
visit any unbeliever who ventured to lay hand upon the holy, bloody
thing. Well we knew it, and as though it had been a venomous
scorpion we, a company of up-to-date, prosaic men of affairs, stood
around that dilapidated markoob, and kept a respectful distance.</p>
<p>Mostyn, an odd figure in pyjamas and dressing-gown, turned his pale,
intellectual face to me as I entered.</p>
<p>"It will have to be put back ... secretly," he said.</p>
<p>His voice was very unsteady. Bristol nodded grimly and glanced at
the two constables, who, with a plain-clothes man unknown to me,
made up that midnight company.</p>
<p>"I'll do it, sir," said one of the constables suddenly.</p>
<p>"One moment"—Mostyn raised his hand!</p>
<p>In the ensuing silence I could hear the heavy breathing of those
around me. We were all looking at the slipper, I think.</p>
<p>"Do you understand, fully," the curator continued, "the risk you
run?"</p>
<p>"I think so, sir," answered the constable; "but I'm prepared to
chance it."</p>
<p>"The hands," resumed Mostyn slowly, "of those who hitherto have
ventured to touch it have been"—he hesitated—"cut off."</p>
<p>"Your career in the Force would be finished if it happened to you,
my lad," said Bristol shortly.</p>
<p>"I suppose they'd look after me," said the man, with grim humour.</p>
<p>"They would if you met with—an accident, in the discharge of your
duty," replied the inspector; "but I haven't ordered you to do it,
and I'm not going to."</p>
<p>"All right, sir," said the man, with a sort of studied truculence,
"I'll take my chance."</p>
<p>I tried to stop him; Mostyn, too, stepped forward, and Bristol
swore frankly. But it was all of no avail.</p>
<p>A sort of chill seemed to claim my very soul when I saw the
constable stoop, unconcernedly pick up the slipper, and replace it
in the broken case.</p>
<p>It was out of a silence cathedral-like, awesome, that he spoke.</p>
<p>"All you want is a new pane of glass, sir," he said—"and the
thing's done."</p>
<p>I anticipate in mentioning it here; but since Constable Hughes
has no further place in these records I may perhaps be excused for
dismissing him at this point.</p>
<p>He was picked up outside the section house on the following evening
with his right hand severed just above the wrist.</p>
