<p>The distant chime of Little Bradley church had struck one o'clock, when
T. B. Smith stepped from the shadow of the hedge on the east side of the
Secret House, and walked slowly toward the road. Two men, crouched in
the darkness, rose silently to meet him.</p>
<p>"I think I have found a place," said T. B., in a low voice. "As I
thought, there are electric alarms on the top of the walls, and electric
wires threaded through all the hedges. There is a break, however, where,
I think, I can circumvent the alarm."</p>
<p>He led the way back to the place from which he had been making his
reconnaissance.</p>
<p>"Here it is," said T. B.</p>
<p>He touched a thin twine-like wire with his finger. The third man put the
concentrated ray of an electric lamp upon it.</p>
<p>"I can make another circuit for this," he said,<span class='pagenum'><SPAN name="Page_161" id="Page_161"></SPAN></span> and pulled a length of
wire from his pocket. Two minutes later, thanks to quick manipulation of
his wire, they were able to step in safety across the wall and drop
noiselessly into the grounds.</p>
<p>"We shall find a man on duty," whispered T. B.; "he is patrolling the
house, and I have an idea that there are trip-wires on the lawn."</p>
<p>He had fixed a funnel-like arrangement to the head of his lamp, and now
he carefully scrutinized the ground as he walked forward. The funnel was
so fixed that it showed no light save on the actual patch of ground he
was surveying.</p>
<p>"Here is one," he said, suddenly.</p>
<p>The party stepped cautiously over the almost invisible line of wire,
supported a few inches from the ground by steel uprights, placed at
regular intervals.</p>
<p>"They fix these every night after sunset; I have watched them doing it,"
said T. B. "There is another line nearer the house."</p>
<p>They found this, too, and carefully negotiated it.</p>
<p>"Down!" whispered T. B. suddenly, and the party sank flat on the turf.</p>
<p>Ela for a moment could not see the cause for alarm, but presently he
discerned the slow moving<span class='pagenum'><SPAN name="Page_162" id="Page_162"></SPAN></span> figure of the sentry as it passed between
them and the house. The man was walking leisurely along, and even in the
starlight they could see the short rifle slung at his shoulder. They
waited until he had disappeared round the corner of the house, and then
crossed the remaining space of lawn. T. B. had been carrying a little
canvas bag, and now he put his hand inside and withdrew by the ears a
struggling rabbit.</p>
<p>"Little friend," he whispered, "You must be sacrificed in the cause of
scientific criminal investigation."</p>
<p>He mounted the steps which led to the entrance hall. The steel-beaded
curtain still hung before the door almost brushing the mat as he had
seen it. He released the rabbit, and the startled beast, after a vain
attempt to escape back to the lawn, went with hesitating hop on to the
mat, and then, at a threatening gesture from T. B., pushed his nose to
the hanging curtain to penetrate his way to safety. Instantly as he
touched it there was a quick flicker of blue light, and the unfortunate
animal was hurled back past T. B. to the gravel path below. The
detective descended hastily and picked it up. It was quite dead. He felt
the singed hair about its head, and murmured a sympathetic "vale."</p>
<p><span class='pagenum'><SPAN name="Page_163" id="Page_163"></SPAN></span></p>
<p>"As I suspected," he said in a low voice, "an electric death-trap for
anybody trying to get into the house that way. Now, Johnson."</p>
<p>The third man was busy pulling out a pair of rubber boots; he took from
his pocket a pair of thick rubber gloves, and made his way with
confidence up the steps. He leant down and tried to pull the mat from
its place, but that was impossible. He gathered up the beads cautiously
with his hands; he was free, by reason of his boots and his
hand-covering, from the danger of a shock, but he took good care that no
portion of the curtain touched any other part of his body. Very
cautiously he drew the bead "chick" aside, looping it back by means of
strong rubber bands, and then T. B. went forward. In the meantime he had
followed the other's example, and had drawn stout rubber goloshes over
his feet and had put on gloves of a similar material. The lock that he
had noticed earlier in the day was of a commonplace type; the only
danger was that the inmates had taken the precaution of bolting or
chaining the door, but apparently they were content with the protection
which their electric curtain might reasonably be expected to afford. The
door opened after a brief manipulation of keys, and T. B. stepped into
the hall. He listened, all his senses strained, for the<span class='pagenum'><SPAN name="Page_164" id="Page_164"></SPAN></span> sound of a
warning bell, but none came. Ela and the other man followed.</p>
<p>"Better remain in the hall," said T. B. "We shall have to chance the
guard not noticing what has happened to the curtain, anyway; perhaps he
will not be round for some time," he added, hopefully.</p>
<p>They made a quick scrutiny of the hall, and found no indication of
cables or of wires which would suggest that an alarm had been fixed. T.
B. stole carefully up the stairs, leaving the two men to guard the hall
below. At every landing he halted, and listened, but the house was
wrapped in silence, and he searched the third floor without mishap.</p>
<p>He recognized the corridor, having taken very careful note of certain
peculiarities, and a scratch on the side of the lift door, which he had
mentally noted for future reference, showed him he was on the right
track.</p>
<p>Unerringly and swiftly he passed along the passage till he came to the
big rosewood doors which opened upon the invalid's bedroom. He turned
the handle gently, it yielded, and he stepped noiselessly through the
door, and pushed the inner door cautiously. The room was dimly
illuminated, evidently by a night light, thought T. B., and he pressed
the door<span class='pagenum'><SPAN name="Page_165" id="Page_165"></SPAN></span> farther open that he might secure a better view of the
apartment, and then he gasped, for this was not the room he had been in
before.</p>
<p>It was a sumptuously arranged bureau, panelled in rosewood, and set
about with costly furniture. A man was sitting at the desk, busily
writing by the light of a table lamp; his back was toward T. B. The
detective pushed the door farther open, and suddenly the man at the desk
leapt up, and turning round, confronted the midnight visitor.</p>
<p>T. B. had only time to see that his face was hidden behind a black mask
which extended from his forehead to his chin. As soon as he saw T. B.
standing in the doorway, he reached out his hand. Instantly the room was
in darkness, and the door, which T. B. was holding ajar, was suddenly
forced back as if by an irresistible power, flinging the detective into
the corridor, which almost simultaneously was flooded with light. T. B.
turned to meet the smiling face of Dr. Fall.</p>
<p>The big man, with his white, expressionless countenance, was regarding
him gravely, and with amused resentment.</p>
<p>Where he had come from T. B. could only conjecture; he had appeared as
if by magic and was fully dressed.</p>
<p><span class='pagenum'><SPAN name="Page_166" id="Page_166"></SPAN></span></p>
<p>"To what do I owe the honour of this visit, Mr. Smith?" he said, in his
dry, grim way.</p>
<p>"A spirit of curiosity," said T. B., coolly. "I was anxious to secure
another peep at your Mr. Moole."</p>
<p>"And how did he look?" asked the other, with a faint smile.</p>
<p>"Unfortunately," said T. B., "I have mistaken the floor, and instead of
seeing our friend, I have unexpectedly and quite unwittingly interrupted
a gentleman who, for reasons best known to himself, has hidden his
face."</p>
<p>Dr. Fall frowned.</p>
<p>"I do not quite follow you," he said.</p>
<p>"Perhaps if I were to follow you back to the room," said T. B.
good-humouredly, "you might understand better."</p>
<p>He heard a strange wailing sound and a shivering motion beneath his
feet, as though a heavy traction engine were passing close to the house.</p>
<p>"What is that?" he asked.</p>
<p>"It is one of the unpleasant consequences of building one's house over a
disused coal-mine," said the doctor easily; "but as regards your strange
hallucination," he went on, "I should rather like to disabuse your mind
of your fantastic vision."</p>
<p>He walked slowly back to the room which T. B.<span class='pagenum'><SPAN name="Page_167" id="Page_167"></SPAN></span> had quitted, and the
inner door yielded to his touch. It was in darkness. Dr. Fall put his
hand inside the room and there was a click of a switch.</p>
<p>"Come in," he said, and T. B. stepped into the room.</p>
<p>It was the room he had left in the earlier part of the day. There was
the blue square of carpet and the silver bedstead, and the same yellow
face and unwinking eyes of the patient. The walls were panelled in
myrtle, the same electrolier hung from the ceiling as he had seen on his
previous visit. Smith gasped, and passed his hand over his forehead.</p>
<p>"You see," said the secretary, "you have been the victim of a peculiar
and unhappy trick of eyesight; in fact, Mr. Smith, may I suggest that
you have been dreaming?"</p>
<p>"You may suggest just what you like," said T. B. pleasantly. "I should
like to see the room below and the room above."</p>
<p>"With pleasure," said the other; "there is a storeroom up above which
you may see if you wish."</p>
<p>He led the way upstairs, unlocked the door of the room immediately over
that which they had just left, and entered. The room was bare, and the
plain deal floor, the distempered walls, and the high skylight showed it
to be just as the doctor had described, a typical storeroom.</p>
<p><span class='pagenum'><SPAN name="Page_168" id="Page_168"></SPAN></span></p>
<p>"You do not seem to use it," said T. B.</p>
<p>"We are very tidy people," smiled the doctor; "and now you shall see the
room below."</p>
<p>As they went down the stairs again they heard the curious wail, and T.
B. experienced a tremulous jar which he had noted before.</p>
<p>"Unpleasant, is it not?" said Dr. Fall. "I was quite alarmed at that at
first, but it has no unpleasant consequences."</p>
<p>On the second floor he entered the third room, immediately below that in
which the sick Mr. Moole was lying. He unlocked this door and they
entered a well-furnished bedroom; on a more elaborate scale than that
which T. B. had seen before.</p>
<p>"This is our spare bedroom," said Dr. Fall, easily; "we seldom use it."</p>
<p>T. B. slipped into the apartment and made a quick scrutiny. There was
nothing of a suspicious character here.</p>
<p>"I hope you are satisfied now," said Dr. Fall as he led the way out,
"and that your two friends below are not growing impatient."</p>
<p>"You have seen them, then," said T. B.</p>
<p>"I have seen them," said the other gravely. "I saw them a few moments
after you entered the hall. You see, Mr. Smith," he went on, "we do not
employ anything so vulgar as bells to alarm<span class='pagenum'><SPAN name="Page_169" id="Page_169"></SPAN></span> us. When the entrance door
opens, a red light shows above my bed. Unfortunately, the moment you
came in I happened to be in an adjoining room at work. I had to go into
my bedroom to get a paper, when I saw the light. So, though I am perhaps
inaccurate in saying that I have been keeping you under observation from
the moment you arrived, there was little you did which was not
witnessed. I will show you, if you will be good enough to accompany me
to my room."</p>
<p>"I shall be delighted," said T. B.</p>
<p>He was curious to learn anything that the house or its custodian could
teach him. Dr. Fall's room was on the first floor, immediately over the
entrance hall, a plain office with a door leading to a cosily, though
comparatively expensively furnished bedroom. By the side of the doctor's
bed was a round pillar, which looked for all the world like one of those
conventional and useless articles of furniture which the suburban
housewife employs to balance a palm upon.</p>
<p>"Look down into that," said the doctor.</p>
<p>T. B. obeyed. It was quite hollow, and a little way down was what
appeared to be a square sheet of silver paper. It was unlike any other
silver paper because it appeared to be alive. He could see figures
standing against it, two figures that he<span class='pagenum'><SPAN name="Page_170" id="Page_170"></SPAN></span> had no difficulty in
recognizing as Ela and Johnson.</p>
<p>"It is a preparation of my own," said the doctor. "I thought of taking
out a patent for it. An adjustment of mirrors throws the image upon a
luminous screen which is so sensitive to light that it can record an
impression of your two friends even in the semi-darkness of the hall."</p>
<p>"Thank you," said T. B.</p>
<p>There was nothing to do but to accept his defeat as graciously as
possible. For baffled he was, caught at every turn, and puzzled,
moreover, by his extraordinary experience.</p>
<p>"You will find some difficulty in opening the door," said the pleasant
Doctor Fall.</p>
<p>"In that I think you are mistaken," smiled T. B.</p>
<p>The doctor stopped to switch on the light, and the two discomforted
detectives watched the scene curiously.</p>
<p>"We have left the door ajar."</p>
<p>"Still I think you will find a difficulty in getting out," insisted the
other. "Open the door."</p>
<p>Ela pulled at it, but it was impossible to move the heavy oaken panel.</p>
<p>"Electrically controlled," said the doctor; "and you can neither move it
one way nor the other. It is an ingenious idea of mine, for which I may
also apply for a patent one of these days."</p>
<p><span class='pagenum'><SPAN name="Page_171" id="Page_171"></SPAN></span></p>
<p>He took a key from his pocket and inserted it in an almost invisible
hole in the oak panelling of the hall; instantly the door opened slowly.</p>
<p>"I wish you a very good night," said Doctor Fall, as they stood on the
steps. "I hope we shall meet again."</p>
<p>"You may be sure," said T. B. Smith, grimly, "that we shall."</p>
