"Do you know, Woodhouse, I have a firm belief that the young fellow has been murdered by some woman! We must search the spot early in the morning and see if we can't find some footprints, or other traces.

Fortunately, it's damp in that hollow, and a woman's heel would leave a well-defined mark. Will you be ready at seven to go back there with me?"

The suggestion had never occurred to me, and my heart stood still when I reflected what tell-tale traces might there be left. But I strove to show no dismay, merely answering--

"Certainly. I'll be ready. We may discover something to give the police a clue."

"Police!" he cried. "They're useless. We shall have a swarm of thick-headed bunglers over here to-morrow. If they sent one smart man down from Scotland Yard they might do some good. But the plain-clothes men of the local constabulary haven't sufficient practice in serious crime to pursue any clever methods of investigation."

"Well, then, at seven," I exclaimed, for we had just reached my gate, and I was anxious to get to my own room and ascertain the nature of the paper I had managed to secure from the lining of the dead man's waistcoat.

"That's an appointment," he said, and as I turned and entered my old-fashioned, ivy-covered house with my latch-key, he pursued his way up the short steep hill towards his home.

Within my own cosy sitting-room the green-shaded reading-lamp was still burning, and Mrs Dawson, my attentive housekeeper, had placed my slippers ready in their accustomed corner. But throwing off my light overcoat I cast myself instantly into my favourite grandfather chair, and drew from my pocket the clue I had surrept.i.tiously stolen.

The piece of paper was pale blue, and as I opened it a cry of dismay involuntarily escaped me.

What was inscribed upon it was so strange!

CHAPTER FIVE.

REVEALS THREE CURIOUS FACTS.

There was no writing on the carefully-concealed sc.r.a.p of paper. Only five rows of numerals, written in a fine feminine hand and arranged in the following manner:--

63 26 59 69 65 56 65 33 59 35 65 44 49 55 22 59 57 46 78 63 23 98 59 39 46 67 82 45 58 35 54 45 46 26 78 75 68 75 49 64 22 86 48 73 78 45 62 45 76 47 64 66 85 44 78 48 73 78 58 62

I turned the paper over, utterly puzzled. It was certainly some cipher, but of a kind of which I knew nothing. Ciphers may of course be very easily constructed and yet defy solution. This appeared to be one of those. What hidden message it contained, I had no idea, save that it was certain to be something of importance and that some other person was in possession of the secret of the decipher, or its recipient would not have concealed it where he did.

If I could only read it, a clue to the dead man's ident.i.ty would no doubt be revealed. But as I glanced at those puzzling rows of numerals I felt that to endeavour to learn their secret was but a vain hope. I had expected to find upon that sc.r.a.p of paper some intelligible letter, and was sorely disappointed at what I had discovered.

The further I pushed my inquiries, the more mysterious the affair seemed to become. A dozen times I tried by ordinary methods to turn the numbers into writing, but my calculations only resulted in an unmeaning array of letters of the alphabet, a chaos quite unintelligible, therefore I was at length compelled to abandon my efforts, and after examining the ring and deciding that it was a copy of one of those old Etruscan rings that I had seen in the British Museum, I reluctantly went upstairs to s.n.a.t.c.h an hour's sleep before the dawn.

My brain was awhirl. Following so quickly the strange declarations of Lolita had come this startling tragedy with all its mysterious and suspicious features. As I lay awake, listening to the solemn striking of the hour from the old church tower which told me that daylight was not far off, I recollected that Lolita had probably recognised the shabby stranger in the tap-room of the _Stanchester Arms_ as she drove past. I remembered how he had held back, as though fearing recognition, and also that, as the carriage went by, her head had been half-turned in our direction. If she had detected his presence she had certainly made no sign, yet it must have been that discovery that had caused her to speak so strangely and to seek my aid in the manner she had done.

Warr still had the sealed letter in his possession, therefore the only way she could have known of the return of the bluff fellow who called himself Richard Keene was by the discovery made by herself.

I remembered her fierce desperation and her trembling fear; how cold her hands had been, and how wild that look in her beautiful eyes--a hunted look such as I had never before seen in the eyes of either man or woman.

Then suddenly I recollected what d.a.m.ning evidence might remain on that soft clay in the hollow where the body had been found. The detectives would certainly be able to establish her presence there! I felt that at all risks I must prevent that. I had promised to help her, and although there were dark suspicions within my heart I intended to act loyally as a man should towards the woman he honestly loves. I therefore set my alarm to awaken me in an hour, and just as the grey light was breaking through the clouds eastward over Monk's Wood, I rose, dressed myself, and concealing a small garden trowel in my pocket set forth for the spot before any of the villagers were astir.

The morning air was keen and fresh as I hurried up the avenue and with some trepidation descended into the hollow, fearing lest the report had already been spread in the village and that any of the curious yokels might notice my presence there.

But I was alone, and therefore breathed more freely.

Over an area of fifteen yards or so the gra.s.s was beaten down here and there, and in the cold grey light became revealed the dark stain where the victim had fallen--the stain of his life blood.

I searched around among the gra.s.s and over the soft boggy places bare of herbage, but found no footmarks nor any trace except that of the downtrodden gra.s.s where the struggle had evidently taken place and where the unknown man had apparently fought desperately for his life. After twenty minutes or so, fearing lest some labourers early astir might come to the spot before going to work, I was about to leave when, of a sudden, in a place where no gra.s.s grew upon the clay, I saw something that held me rigid.

In the soft earth was the plain imprint of the small sole of a woman's shoe, with a Louis XV heel!

Lolita wore high heels of exactly that character, and took three's in shoes. Was it possible that the footprint was hers?

As I looked I saw others, both of a person advancing and receding. One was ill-defined, where she had apparently slipped upon the clay. But all of them I stamped out--all, indeed, that I could find. Yet was it possible, I wondered, to efface every one?

If one single one remained, it might be sufficient to throw suspicion upon her.

While engaged in this, something white caught my eye lying upon the gra.s.s about ten yards distant. I picked it up and found it to be a piece of white fur about an inch square that had evidently been torn bodily out of a boa or cape--the same fur that had been found between the dead man's fingers.

This I placed carefully in my cigarette-case and continued my work of effacing the d.a.m.ning footprints. There were other marks, of men's boots, but whether those of the dead man or of our own I could not decide, so I left them as evidence for the police to investigate.

My eyes were everywhere to try and discover the weapon with which the foul deed had been committed, for the a.s.sa.s.sin, I thought, might have cast it away, but my search was in vain. It had disappeared.

Fully twenty distinct marks of those small well-shod feet I effaced by stamping upon them or sc.r.a.ping the surface with the trowel, and was preparing to return and keep the appointment with the doctor when of a sudden I saw, lying close behind the trunk of the giant oak, a half-smoked cigarette, which on taking up I found to be of the same brand as those found in the dead man's pocket. He had therefore kept a tryst at that spot, and had smoked calmly and unsuspiciously in order to while away the time.

Of men's footprints in the soft ground there were a quant.i.ty, but then I remembered how all four of us had tramped about there, in addition to the victim himself, and I was not sufficiently expert in tracking to be able to distinguish one man's tread from another's.

It was already daylight and in the distance I could hear the sound of a reaping machine in one of the fields beyond the park, therefore I was compelled to escape in order that my premature examination should remain secret. So I struck straight across the level sward to the London road, which ran beyond the park boundary, in preference to pa.s.sing straight down the avenue at risk of meeting any of the labourers.

News of the tragedy I knew had not yet reached the Hall, otherwise the servants would have been out to see the spot, therefore I believed myself quite safe from detection until, just as I scaled the old stone wall and dropped into the broad white high road with its long line of telegraph lines, I encountered the innkeeper Warr who, mounted on his bicycle, was riding towards me.

He had approached noiselessly and we were mutually surprised to meet each other in such circ.u.mstances.

"Halloa!" he cried, dismounting. "You've been out again very early-- eh?"

"I've been back to the spot to see if I could find any traces of the dead man's a.s.sailant," was my reply. "I thought I'd go back early, before the crowd trod over the place. Don't say anything, or Knight may consider that I've taken his duty out of his hands."

"Ah, a very good idea, sir," was the man's approving response. "I thought of doing so myself, only they're beginning to cut my bit o'

wheat in the mill-field this morning and I have to go into Thrapston about the machine. I'll be back in an hour."

He was preparing to re-mount, when I stopped him, saying--

"Look here, Warr. You recollect that stranger who called and left the note for Lady Lolita last evening? Well, there seems considerable mystery about the affair, and somehow I feel there's connexion with the fellow's visit with this poor young man's death. If so, her ladyship's name must be rigorously kept out of it, you understand. There's to be an inquest to-morrow, and we shall both be called to give evidence.

Recollect that not a word is said about the man Keene, the note, or the message."

"If you wish it, sir, I'll keep a still tongue," was his reply. "I've told n.o.body up to now--not even the missus."

"Very well. Remember only you and I know of this man's return, and the knowledge must go no further. There's a mystery, but it must have no connexion with her ladyship."

"You may trust me, sir. The family have been too good to me all these years for me not to try and render them a service. I quite agree with you that the stranger was suspicious, and from what he said to me in private it is certain that he must know her ladyship very well indeed."

"You're sure you've never seen that young man before?" I asked, watching his face narrowly.

"Him? No, I don't know him from Adam!" was the landlord's reply, yet uttered in a manner and tone that aroused my distinct suspicions. His a.s.surance was just a trifle too emphatic, I thought.

I paused a moment, half inclined to express my doubt openly, then said at last--

"That letter--what shall you do with it?"

"Give it to her, of course. I'll come up to the Hall when I come back.
