<h2><span>CHAPTER XLV</span> <span class="smaller">BAFFLED</span></h2>
<p>Geoffrey had not long to wait. From where he was standing he could see
down into the vault perfectly well. He would have been better satisfied
had he understood what those people were talking about, but their words
conveyed nothing to him.</p>
<p>On the floor of the vault the queer-looking machinery was spread out,
and to the ends of the india-rubber tubes wires were attached. No sooner
had this been accomplished than the woman, after giving some rapid
instructions to her allies, left the vault. She was so quick that
Geoffrey barely had time to conceal himself behind a pillar before she
passed him.</p>
<p>The woman was masked and disguised beyond recognition, but Geoffrey had
no need to be told who she was. He knew that he was in the presence of
Mrs. May. And, despite his knowledge of her cleverness and resource, he
found himself marveling to see her display so fine a knowledge of the
house.</p>
<p>The woman passed along, dragging a number of fine light wires after her.
The other ends of the wires were attached to the queer-looking apparatus
in the vault.</p>
<p>Mrs. May went along the passages, along the corridor, and up the stairs
as if she had been accustomed to the house all her life. Surely she must
have been here many times before, or she would not have exhibited such
fearless confidence. The idea of the black, gliding figure creeping
about the house in the dead of night filled Geoffrey with loathing.</p>
<p><span class="pagenum"><SPAN name="Page_245" id="Page_245">[Pg 245]</SPAN></span></p>
<p>All the same, he did not neglect his opportunities. He followed swiftly
and silently until he came to the main corridor on the first landing.
Here, to his surprise, the woman turned into one of the bed-rooms, the
room used by the head of the house. She closed the door behind her.</p>
<p>What to do next? But Geoffrey was not long in doubt. Ralph was standing
by his side, a dark lantern in his hand.</p>
<p>"Where did she go?" he whispered.</p>
<p>"You heard her, then?" asked Geoffrey.</p>
<p>"Of course, I heard everything. I see with my ears. Naturally you
guessed who she was. But what room did she go into?"</p>
<p>"My grandfather's."</p>
<p>"So I expected. But she means to visit all the rooms in turn. You need
not be afraid, she will be there for some minutes. What do you see
outside?"</p>
<p>Geoffrey made a close examination with the lantern.</p>
<p>"I see a tangle of small wires on the floor," he said. "They come up
from the vaults."</p>
<p>"Where they are attached to a queer-looking instrument?"</p>
<p>"Yes, yes. I see you know all about it. One of the wires runs under the
door into the room where Mrs. May is engaged."</p>
<p>"And where she will be engaged for some time," said Ralph. "Move that
book ladder and look over the fanlight."</p>
<p>There were books on high shelves in the corridor, and a light
librarian's ladder close at hand. Geoffrey propped this against the door
and looked in through the open fanlight. All the bed-room doors had
fanlights at Ravenspur.</p>
<p>The lantern inside was on the dressing-table and, standing on a chair by
a fireplace, was Mrs. May. She had pinned the thin wire to the wall
cunningly, and had turned the end of it into a plate that stood on the
mantel<span class="pagenum"><SPAN name="Page_246" id="Page_246">[Pg 246]</SPAN></span> shelf. From a flask she poured a little white powder into the
plate.</p>
<p>This done she seemed to be satisfied. Geoffrey whipped the ladder away
and the woman emerged from the room. Once more she went along the
corridor with firm, resolute step, and the air of one who knows what she
is doing and has a definite object in view.</p>
<p>From one bed-room to another she went, leaving a wire in each until
every room occupied by one of the Ravenspur family had been visited.
Geoffrey's room was the last. When she had finished here she took up a
pair of scissors and tapped the wire. Outside the door Geoffrey and
Ralph could hear the noise distinctly.</p>
<p>Ralph's jaws came together with a click.</p>
<p>"The key is outside your room door," he whispered. "Turn it."</p>
<p>Geoffrey wondered, but he hastened to comply. The key turned with an
ease and silence that testified to the fact of its having been carefully
oiled.</p>
<p>"What does it all mean?" Geoffrey whispered.</p>
<p>"She is going to test her machinery," said Ralph with a chuckle. "And
she is going one step farther to her own destruction. Listen."</p>
<p>Again came the faint tap, and then down from far below the purring jar
of electrical apparatus in motion. There was silence inside the room for
a moment and then Geoffrey saw the handle turn. It was turned softly at
first, then more quickly, and finally it was tugged as an angry child
snatches at a toy.</p>
<p>Ralph chuckled. The diabolical mirth seemed to come deep from his
throat.</p>
<p>"She is trying to get out," Geoffrey whispered.</p>
<p>"Of course she is," Ralph replied. "But not quite yet."</p>
<p>The lock was rattling loudly by this time; there was a half-angry,
half-frightened muttering from within. And then there came a long,
piercing, wailing scream, as of a woman in the last agony before death.</p>
<p><span class="pagenum"><SPAN name="Page_247" id="Page_247">[Pg 247]</SPAN></span></p>
<p>Geoffrey would have started back, but Ralph restrained him.</p>
<p>"No, no," he whispered violently. "It is all right; everything is
turning out splendidly."</p>
<p>"But she is a woman and in deadly peril, uncle."</p>
<p>"I know it, lad. Five minutes more and that fiend will be beyond further
mischief. She has been trying the effect of her infernal contrivance and
will be hoist with her own petard. She is scared to death. She imagines
she has fastened herself in and can't get out."</p>
<p>"But this is murder," Geoffrey cried.</p>
<p>"I dare say some people would call it so," Ralph replied coolly. "As a
matter of fact, there never could be homicide more justifiable than to
let that woman perish there. Still, we are not going to do anything of
the kind. When those cries cease, and you hear yonder wretch fall to the
ground, then open the door and drag her out."</p>
<p>The cries were coming wildly from behind the door; there was a hammering
on the panels. The cries rang through the house, they reached the
Asiatics in the vaults and the latter fled in terror into the night.</p>
<p>Something had happened, but what it was they did not care. They had only
themselves to think of.</p>
<p>In spite of his strong nerves, Geoffrey shuddered. It was horrible to be
alone in that grim house of tears, waiting in the darkness, opposed by
grim horrors and, above all, to have that note of agony ringing in his
ears.</p>
<p>Would it never stop? Would the time to act never come? Geoffrey would
have interfered in spite of everything but for the fact that Ralph was
gripping his shoulder in a grasp that at any other time would have been
painful.</p>
<p>Suddenly the noise ceased. There was a moan and the soft, crushing fall
of a body. Ralph's face blazed up instantly.</p>
<p>"Now," he cried, "there is no time to be lost."</p>
<p>Geoffrey darted forward. He had the door opened in<span class="pagenum"><SPAN name="Page_248" id="Page_248">[Pg 248]</SPAN></span> an instant. Mrs. May
lay still and white on the floor. The atmosphere of the room seemed to
have vanished. It was intolerable to breathe there; air there was none.</p>
<p>As the door fell back the room filled as with a sudden strong draught.
Geoffrey dragged the unconscious figure into the corridor.</p>
<p>"Will she die?" he gasped.</p>
<p>"No, she will not die," Ralph said coolly. "Had I intended her to die I
should not have allowed you to open the door. Pick her up and throw her
on one of the beds in a spare room. She will require no attention, but
she will not attain consciousness for some hours. And, after that, she
will be useless for a day or two. You need not worry; our scheme is
working out splendidly. Pick her up."</p>
<p>Ralph indicated the still figure with brutal indifference. He would have
shown more consideration to a sick dog. Geoffrey complied, and presently
made the woman as comfortable as circumstances allowed.</p>
<p>Geoffrey had hardly done so before there was a light footfall in the
corridor, and Tchigorsky appeared, still in disguise.</p>
<p>"I gather that things are well," he said. "Just now I met that
she-devil's accomplices fleeing as if the Father of Lies was behind
them. She was trapped, eh?"</p>
<p>Ralph nodded and chuckled.</p>
<p>"In Geoffrey's room," he explained. "When she was testing her apparatus
I had the key turned on her. And she could not get out. I let her remain
there as long as I considered it safe to do so, and her yells must have
alarmed her confederates. Probably they have fled, leaving things
intact."</p>
<p>"Probably," said Tchigorsky. "I will go and see."</p>
<p>He was back again presently, a pleased expression on his face.</p>
<p>"Nothing has been touched," he said. "I have removed the wires, in case
of danger. We have the lady more or less under our thumb."</p>
<p><span class="pagenum"><SPAN name="Page_249" id="Page_249">[Pg 249]</SPAN></span></p>
<p>"What was she doing?" Geoffrey asked.</p>
<p>"It is an appliance for exhausting air," Tchigorsky explained. "You take
a powder and place it on a hot plate. Directly it begins to burn it
draws up all the air. The thing has been known in the East for thousands
of years. Mrs. May applied electricity to give her greater scope. A
plate of the powder was to be heated in the room of everybody in the
castle when asleep.</p>
<p>"A few minutes and the thing is done. Then the wires are withdrawn and
gradually the different rooms fill with air again. The burnt powder
leaves no trace. Then you are all found dead in your beds and nobody
knows how it is done. The wires are easily drawn back to the battery and
the whole thing is destroyed."</p>
<p>Geoffrey shuddered.</p>
<p>"What a fiend!"</p>
