"Do, I beg of you, tell me more of this affair, Mr. Kirk," I urged,
speaking quickly. "If you are really my friend, if you really wish me
to assist you, why not instruct me how to act? If you will tell me the
truth, I will keep a still tongue."
"You will be more silent if you remain in ignorance," was his response.
"Listen! I must get away," and before I could prevent him he had closed
the door quietly behind him. I noticed that he was attired in clothes
quite different from his usual habit. Indeed, he was smartly dressed,
wearing a black overcoat with a velvet collar, and well-ironed silk hat.
"Stay and face Langton," I urged. "Take him into your confidence.
Surely no good can be served by this elusiveness."
"You don't know what you're saying, man!" he cried. "Let me pass. I've
been listening to all you told the young man. Your story was quite a
feasible one. Keep it up, and affect entire ignorance of me. It is the
only way if we are to place our hand upon poor Greer's assassin."
"The proper course for me to pursue, Mr. Kirk, is to--"
"Footsteps! I must go!" he cried hoarsely, in a voice which plainly
betrayed his intense agitation and anxiety not to come face to face with
the dead girl's lover. "I'll try and see you to-morrow or next day.
Remain in patience till you hear from me. Good-bye."
And the next instant he ran lightly down the steps and sped away to the
left, out of sight. All this had happened within three minutes.
Scarce had he disappeared, when Langton, accompanied by two constables,
turned the corner, and found me on guard at the door. I felt
bewildered. Kirk's sudden appearance at the door of that house of
mystery had taken me so aback that I had scarcely yet recovered. Did
not his admission that the faithful Antonio had left bear out Langton's
story of having seen the fellow passing through the buffet at Calais
station?
The young man had, I saw, been explaining his suspicions to the
constables on their way to the house. I was glad that there was only a
blank wall opposite, otherwise my action in allowing Kirk to leave the
place might easily have been observed and misconstrued.
What, I wondered, was the reason of my strange friend being in there
alone? Why had the lights been so suddenly extinguished when Langton
had rung the bell? That he feared Langton was evident.
Why?
Within myself I resolved to put some guarded questions and ascertain, if
possible, what Ethelwynn's lover knew of this man who had so ingeniously
drawn me into that maelstrom of doubt and grim tragedy.
The two constables were instantly on the alert. They examined the lock
of the front door, conversing in low whispers, then, after a brief
consultation, one of the pair left hurriedly, in order to place a guard
upon the front of the premises, overlooking the garden, which divided
the crescent from the park.
Presently he returned, accompanied by a brown-bearded sergeant, who
recognised Langton as having been witness in a motor-car accident in
Cumberland Terrace a couple of months before.
The sergeant pressed the button of the electric bell for a long time,
and though we waited anxiously there was, of course, no response.
"I'm certain somebody is within," declared Langton excitedly; "I saw the
light quite distinctly."
"Very well, sir, if you're certain," replied the sergeant gruffly,
"we'll have to force an entry. But remember, if you're mistaken, it
will be a trifle awkward. The owner might come upon you for damage."
"I'll stand the racket of all that," declared the young man readily.
"There are thieves in here, I'm certain."
"It may be only a maid who has a visitor, and who believes her master,
or young mistress, has returned," I suggested, full of apprehension at
the alarming discovery which must be made as soon as the police entered
and searched the place.
"Then all the worse for her, sir," answered one of the constables
grimly.
And again they banged at the door and continued ringing. All, however,
was silence and darkness.
What would they have thought had they known that I had allowed the
mysterious Kirk, who had been lurking there, to escape?
Had I acted foolishly in doing so? I was forced to the conclusion that
I had.
While sergeant and constables were in counsel as to what course should
be adopted, an inspector, who had been warned by the constable on guard
at the front, arrived, and was told Langton's story.
"This is Professor Greer's," he remarked; "I think we'd better force an
entry, sergeant. That basement window down there looks easy of access,"
and he pointed to a window of the back-kitchen.
"Yes," replied the bearded man addressed, as a constable shone his
lantern down upon it, "we could break the glass and turn back the catch.
There are no bars there."
This course was quickly adopted. The inspector, taking one of the men's
truncheons, tapped the glass lightly until he had cracked it, and then
pulled the pieces forward till he could insert his hand and release the
catch.
The window thus opened, the two constables, truncheons in hand and
lights turned on, crept into the kitchen and disappeared, while we stood
waiting anxiously without, our ears strained in listening.
A few moments later, one of the men threw open the front door, and
together we entered the dark and silent house of mystery.
I stood back, passing into the wide hall last of all. There was now no
hiding the grim, astounding truth from police and public.
I held my breath, awaiting the sensation that must be caused by the
discovery.
As I anticipated, a discovery was made very quickly.
But, strangely enough, it was not at all what I had looked for. It only
added further mystery to the altogether inscrutable problem.
