Thank goodness, they are all safe under lock and key.Either the fear of the law or the Duke's purse will certainly get out of them all that they know.""So far, so good," said Holmes, when the doctor had at last left the room."It at least bears out the theory that it is on the side of the Lower Gill Moor that we must hope for results.
The police have really done nothing locally, save the arrest of these gipsies.Look here, Watson! There is a watercourse across the moor.You see it marked here in the map.In some parts it widens into a morass.This is particularly so in the region between Holdernesse Hall and the school.It is vain to look elsewhere for tracks in this dry weather; but at THAT point there is certainly a chance of some record being left.I will call you early to-morrow morning, and you and I will try if we can throw some little light upon the mystery."The day was just breaking when I woke to find the long, thin form of Holmes by my bedside.He was fully dressed, and had apparently already been out.
"I have done the lawn and the bicycle shed," said he.
"I have also had a ramble through the Ragged Shaw.Now, Watson, there is cocoa ready in the next room.I must beg you to hurry, for we have a great day before us."His eyes shone, and his cheek was flushed with the exhilaration of the master workman who sees his work lie ready before him.
A very different Holmes, this active, alert man, from the introspective and pallid dreamer of Baker Street.I felt, as I looked upon that supple figure, alive with nervous energy, that it was indeed a strenuous day that awaited us.
And yet it opened in the blackest disappointment.With high hopes we struck across the peaty, russet moor, intersected with a thousand sheep paths, until we came to the broad, light-green belt which marked the morass between us and Holdernesse.
Certainly, if the lad had gone homewards, he must have passed this, and he could not pass it without leaving his traces.
But no sign of him or the German could be seen.With a darkening face my friend strode along the margin, eagerly observant of every muddy stain upon the mossy surface.Sheep-marks there were in profusion, and at one place, some miles down, cows had left their tracks.Nothing more.
"Check number one," said Holmes, looking gloomily over the rolling expanse of the moor."There is another morass down yonder and a narrow neck between.Halloa! halloa! halloa!
what have we here?"
We had come on a small black ribbon of pathway.In the middle of it, clearly marked on the sodden soil, was the track of a bicycle.
"Hurrah!" I cried."We have it."
But Holmes was shaking his head, and his face was puzzled and expectant rather than joyous.
"A bicycle, certainly, but not THE bicycle," said he.
"I am familiar with forty-two different impressions left by tyres.
This, as you perceive, is a Dunlop, with a patch upon the outer cover.
Heidegger's tyres were Palmer's, leaving longitudinal stripes.
Aveling, the mathematical master, was sure upon the point.
Therefore, it is not Heidegger's track."
"The boy's, then?"
"Possibly, if we could prove a bicycle to have been in his possession.But this we have utterly failed to do.This track, as you perceive, was made by a rider who was going from the direction of the school.""Or towards it?"
"No, no, my dear Watson.The more deeply sunk impression is, of course, the hind wheel, upon which the weight rests.
You perceive several places where it has passed across and obliterated the more shallow mark of the front one.It was undoubtedly heading away from the school.It may or may not be connected with our inquiry, but we will follow it backwards before we go any farther."We did so, and at the end of a few hundred yards lost the tracks as we emerged from the boggy portion of the moor.Following the path backwards, we picked out another spot, where a spring trickled across it.Here, once again, was the mark of the bicycle, though nearly obliterated by the hoofs of cows.After that there was no sign, but the path ran right on into Ragged Shaw, the wood which backed on to the school.From this wood the cycle must have emerged.Holmes sat down on a boulder and rested his chin in his hands.I had smoked two cigarettes before he moved.
"Well, well," said he, at last."It is, of course, possible that a cunning man might change the tyre of his bicycle in order to leave unfamiliar tracks.A criminal who was capable of such a thought is a man whom I should be proud to do business with.
We will leave this question undecided and hark back to our morass again, for we have left a good deal unexplored."We continued our systematic survey of the edge of the sodden portion of the moor, and soon our perseverance was gloriously rewarded.Right across the lower part of the bog lay a miry path.Holmes gave a cry of delight as he approached it.
An impression like a fine bundle of telegraph wires ran down the centre of it.It was the Palmer tyre.
"Here is Herr Heidegger, sure enough!" cried Holmes, exultantly.
"My reasoning seems to have been pretty sound, Watson.""I congratulate you."
"But we have a long way still to go.Kindly walk clear of the path.Now let us follow the trail.I fear that it will not lead very far."We found, however, as we advanced that this portion of the moor is intersected with soft patches, and, though we frequently lost sight of the track, we always succeeded in picking it up once more.
"Do you observe," said Holmes, "that the rider is now undoubtedly forcing the pace? There can be no doubt of it.
Look at this impression, where you get both tyres clear.
The one is as deep as the other.That can only mean that the rider is throwing his weight on to the handle-bar, as a man does when he is sprinting.By Jove! he has had a fall."There was a broad, irregular smudge covering some yards of the track.Then there were a few footmarks, and the tyre reappeared once more.
"A side-slip," I suggested.
