<h2><SPAN name="page205"></SPAN><span class="pagenum"></span>CHAPTER XVIII<br/> THE ANONYMOUS LETTERS</h2>
<p><span class="smcap">The</span> first thing I had to settle was
as regards the entrance to White Towers of which Kitty Clevedon
had spoken. We had to pick up Billy Clevedon’s tracks
after he left Midlington, and if he really had gone to White
Towers, it would probably be by that route. At all events
there was absolutely no evidence he had been seen at any of the
usual entrances. Kitty agreed to guide us, and told us to
meet her the following morning at the main gates to White Towers;
and she advised us also to put on some old clothes as we should
have to creep part of the way on hands and knees.</p>
<p>We were prompt to time and Kitty took us through the park to
some very rough ground at the rear of the house, though not far
away from it, and there she showed us a narrow cleft in a mass of
rock and told us that was the entrance. It was partly
choked by a jumble of fallen boulders overgrown with the rough <SPAN name="page206"></SPAN><span class="pagenum"></span>vegetation
of the moor, probably rank enough at some periods of the year,
but lying now for the most part dry and dead. I looked for
any sign of recent entrance, especially for footmarks; but the
ground was too hard and revealed nothing, though the rubbish at
the entrance seemed to have some appearance of being
trampled. I took out my flash lamp and pushed my way into
the opening, followed by the others, though it was a very tight
fit for Thoyne.</p>
<p>A wall of rock confronted us at about four feet, but Kitty
bade us turn to the left and there I saw an opening low down
which seemed to lead to a passage that descended somewhere into a
mass of pitch darkness. We had to get on hands and knees
and crawl along so for quite a long distance through a low,
narrow tunnel that appeared to be for the most part natural,
though here and there, it had evidently been widened at least, if
not entirely pierced by human agency.</p>
<p>Presently, after going steadily downwards for many yards, it
went forward on the level, and was there a little higher and
wider; but at no point did it enable us to stand erect. It
was a case of creeping all the way. I understood now why
Kitty had advised the oldest possible <SPAN name="page207"></SPAN><span class="pagenum"></span>clothing. It meant ruin to the
knees of one’s trousers. And then the tunnel ended
abruptly against a wall of solid rock; but Kitty cried out that
there was an iron ring close to my right hand, and that I must
take hold of it and pull hard.</p>
<p>I obeyed; there was a grinding and groaning as of rusty
machinery and then the rock in front swung back and we found
ourselves in an open chamber with walls and floor of natural
rock, but a roof of worked stone formed of square flags, all save
one supported by pillars of rusty iron. There were nine
stone flags, each six feet by four, and eight pillars, and the
dimensions of the cellar or cave were thus eighteen feet by
twelve. The height would probably be about eight
feet. We could at least stand upright. I took my
flash lamp and carefully examined every corner, not, as it turned
out, quite unremuneratively. I dropped my hat and then
stooped to pick it up again—and with it something I had
noticed lying there.</p>
<p>My find was a hairpin still fresh and bright and with no sign
of rust about it.</p>
<p>If Kitty Clevedon had passed that way I should have supposed
that she had dropped it. Ladies shed things of that sort as
they go. But she had assured us that she had not been near
<SPAN name="page208"></SPAN><span class="pagenum"></span>the
spot; in which case a knowledge of the existence of the passage,
supposed to be confined to Kitty and her brother, was shared by
someone else, and that a woman.</p>
<p>“Which is the way out?” I asked, saying nothing of
the hairpin which, at a favourable opportunity, I thrust into my
waistcoat pocket.</p>
<p>Kitty pointed to the one unsupported flagstone and told us
that it worked on a swivel and could be pushed up if one could
reach it, whereupon Thoyne swarmed up the nearest pillar and
tried to move the stone but failed, though whether because the
axle was rusty or because there was some fastening on the other
side we could not say. Thoyne selected another pillar and
once more gave the stone a push, but with no more success than
before. From his position, clinging monkey-like to the
pillar, he could exert very little leverage. He slid down
again and suggested that I should mount his shoulders so as to be
right under the stone, a manœuvre which was promptly
attempted with satisfactory results.</p>
<p>The stone moved, though slowly and stubbornly and with much
creaking and, swinging myself up through the opening thus
disclosed, I found myself in a cellar full of a miscellaneous
collection of rubbish, baskets, boxes, barrels, <SPAN name="page209"></SPAN><span class="pagenum"></span>chairs,
broken furniture of all sorts, books and papers and so on.
I fixed the stone in position, because left to itself it would
simply have swung back again into its place, and then I passed
down to the others a short ladder which I found lying against one
of the walls of the cellar.</p>
<p>When the others had joined me, Kitty explained that we were
under the older portion of White Towers, the East Wing, which was
partly in ruins and uninhabited.</p>
<p>I was easily able to explain the tunnel—I had seen
something of the sort in other old houses. It was simply a
way of escape for those inside if enemies became too
pressing. Peakshire had played a strenuous part in the
Civil War, most of the big men being on the side of the King and
White Towers, the older part of which dated back beyond
Elizabeth, had probably been a Royalist stronghold and meeting
place. If enemies, in the shape of Cromwell’s men,
came along, the Cavaliers would only have to creep through the
tunnel in order to escape the Roundheads. Or it may have
been constructed in even earlier days for the benefit of Roman
Catholic refugees.</p>
<p>That, however, was mere speculation, though not without
interest. For many years evidently it had been unused and
forgotten until it was <SPAN name="page210"></SPAN><span class="pagenum"></span>rediscovered by the two children who
had kept it a delightful secret to themselves and had, no doubt,
brought it into many exciting games. The question for us,
however, was—had Clevedon used it recently, and if so, for
what purpose? It was certainly interesting and possibly
significant that somebody evidently had been that way not so very
long before. But Clevedon at all events did not use
hairpins.</p>
<p>“There seems to be no evidence that your brother ever
came this way,” I said, as we stood looking round us.
“True, the vegetation at the entrance to that passage bore
some appearance of having been trampled down, though that may
have been the weather or—”</p>
<p>“I did that,” Thoyne broke in quickly.
“Kitty told me about this before I saw you and I went to
look for myself.”</p>
<p>I glanced at him casually. It was quite likely he spoke
the truth.</p>
<p>“Did you get as far as this?” I asked.</p>
<p>“Oh, no, I didn’t get beyond the
entrance.”</p>
<p>“And you think you trampled that brushwood?”</p>
<p>“I—it is possible I may have done.”</p>
<p>“You did not notice its condition
before—?”</p>
<p>“No, I didn’t, I wasn’t looking for
that. I see you still distrust me,” he added quickly,
<SPAN name="page211"></SPAN><span class="pagenum">p.
211</span>“but I am perfectly honest about it. I am
sorry I came.”</p>
<p>“Oh, it doesn’t matter,” I returned
carelessly. “If you hadn’t been there, the
signs might have proved that Clevedon hadn’t either,
whereas now it is an open question. But the fact that
somebody may have been there is of minor importance unless there
is accompanying evidence that the somebody was Clevedon
himself. Of course, there is the fact that he alone knew of
the entrance—he and one other. I suppose you
haven’t been here lately?”</p>
<p>I turned suddenly on Kitty Clevedon and rapped out the
question with the abruptness of a pistol shot. She started
a little, then shook her head.</p>
<p>“Not since I was a child,” she replied.</p>
<p>“Can we get out of this without returning by that
passage?” I asked.</p>
<p>“Yes, through that door is a flight of stone steps
leading to what used to be the kitchen of the old White
Abbey.”</p>
<p>“We’ll go that way,” I decided.</p>
<p>When I had parted from my two companions, with a promise to
see them again later in the day, or, possibly on the following
morning, I went into the post office and from my waistcoat pocket
produced a hairpin.</p>
<p><SPAN name="page212"></SPAN><span class="pagenum">p.
212</span>“Have you any of that sort in stock?” I
asked, then, noting her look of surprise, I added, “I hope
you won’t give me away if I tell you that I use them to
clean my pipe. They are the best things I know for
that.”</p>
<p>“Well, I didn’t suppose you wanted them for your
hair,” she said pertly. “Yes, we have plenty of
that sort in stock. Indeed, I don’t think we have any
others.”</p>
<p>“Then I suppose every lady in the Dale uses them,”
I remarked jestingly.</p>
<p>“Most of them,” she agreed. “I
do—see, here is one”—and she extracted a
specimen from her own abundant head-covering. “A few
may get some others when they go into Midlington, but most come
here for them. Lady Clevedon had three boxes only a week
ago.”</p>
<p>“Lady Clevedon,” I echoed, “then they must
be an aristocratic brand. Does her ladyship do her own
shopping?”</p>
<p>“Oh, they are good enough. No, Lady Clevedon
didn’t come for them—Miss Kitty fetched them.
She said they were for Lady Clevedon, but she took some for
herself too, so I suppose she wears them.”</p>
<p>Evidently the hairpin was not going to be of much use to me,
at all events as a means of <SPAN name="page213"></SPAN><span class="pagenum"></span>identification. There would be
too many of them about the Dale for that.</p>
<p>When I reached Stone Hollow again I found Detective Pepster
awaiting me, looking, for him, a little disconsolate.</p>
<p>“Well,” was my greeting, “how has Fate
treated you?”</p>
<p>“No luck, none at all,” Pepster said
gloomily. “I am just back from Dublin with no
news. Clevedon went to Dublin on February 20th, but there
all trace of him ended. I could learn nothing.”</p>
<p>“I have been more fortunate than you,” I returned
smilingly. “I can carry him a bit farther than
that. He was in Midlington on February 22nd and left there
on the morning of the 23rd.”</p>
<p>“Do you <i>know</i> that?”</p>
<p>“Yes, for certain.”</p>
<p>“Did he go to Cartordale—to White
Towers?”</p>
<p>“I can’t say for that.”</p>
<p>“And where is he now?”</p>
<p>“Nobody knows.”</p>
<p>“And his sister—?”</p>
<p>“Is as ignorant as you or I.”</p>
<p>“She is bluffing?”</p>
<p>“No.”</p>
<p>“She really doesn’t know where he is?”</p>
<p>“She really doesn’t.”</p>
<p><SPAN name="page214"></SPAN><span class="pagenum">p.
214</span>“But—anyway we must find him.”</p>
<p>“I am busy at it now.”</p>
<p>“Any traces?”</p>
<p>“None.”</p>
<p>“It is a weird development. Did he do it? Is
he keeping out of the way because—?”</p>
<p>“It is impossible to say. We know that he came to
Midlington, but that he came to Cartordale or ever had any
prussic acid in his possession—”</p>
<p>“Yes, you’re right. We must bring him a
little nearer than Midlington. But if he didn’t do
it, or, for the matter of that, if he did, he is a fool for
keeping out of the way.”</p>
<p>Which at least was a self-evident proposition.</p>
<p>“And now that we have disposed of Billy Clevedon for the
time being,” Pepster went on, “tell me what you think
of this.”</p>
<p>With great deliberation he took a letter-case from his pocket
and from it extracted a sheet of paper which he handed over to
me. It was lined paper, torn evidently from a notebook, and
on it was printed in capitals:</p>
<blockquote><p style="text-align: center">YOU ARE ON THE WRONG<br/>
TRAIL ALTOGETHER. IF<br/>
YOU WANT TO KNOW WHO<br/>
KILLED CLEVEDON KEEP<br/>
YOUR EYE ON THOYNE.</p>
</blockquote>
<p><SPAN name="page215"></SPAN><span class="pagenum">p.
215</span>“That is No. 1,” Pepster said.
“Here is No. 2.”</p>
<p>He handed me a second document, but this time it was a plain
white paper on which the ink had run rather badly, though the
letters were quite legible. It was, too, much shorter,
simply reading:</p>
<blockquote><p style="text-align: center">THOYNE MURDERED
CLEVEDON.</p>
</blockquote>
<p>“Anonymous letters by some crank, who thinks he has made
a discovery,” I remarked.</p>
<p>“Yes,” Pepster agreed, “but here is No.
3.”</p>
<p>The third communication was written in red ink on a
buff-coloured slip of paper, such as Government offices use, and
read:</p>
<blockquote><p style="text-align: center">YOU ARE MISSING YOUR<br/>
LIFE’S CHANCE. ARREST<br/>
THOYNE AND I WILL PRODUCE<br/>
THE EVIDENCE.<br/>
TRUST ME.</p>
</blockquote>
<p>“Were they addressed to you personally?”</p>
<p>“Yes, and to my private address.”</p>
<p>“Apparently somebody who knows you.”</p>
<p>“Looks like it.”</p>
<p>“Come by post?”</p>
<p><SPAN name="page216"></SPAN><span class="pagenum">p.
216</span>“Yes.”</p>
<p>“Postmark?”</p>
<p>“Two Cartordale, the third Midlington. Now, is the
writer merely a crank, or has he something up his
sleeve?”</p>
<p>“If you do nothing he’ll probably write again and
may be more explicit.”</p>
<p>“Well, of course, Thoyne is very deep in this thing, but
there is nothing definite connecting him with the murder—is
there?”</p>
<p>But I merely shook my head vaguely at that. In this
curious case one never knew what a day might bring forth.
The changes and developments were as rapid as a cinema show.</p>
