But as they were walking together, after pa.s.sing Northend, a curious thing happened.

Summers started back suddenly and nudged the novelist's arm without a word.

Fetherston, looking in the direction indicated, halted, utterly staggered by what met his gaze.

It was inexplicable--incredible! He looked again, scarcely believing his own eyes, for what he saw made plain a ghastly truth.

He stood rigid, staring straight before him.

Was it possible that at last he was actually within measurable distance of the solution of the mystery?

CHAPTER XXVII

THE RESULT OF INVESTIGATION

AS the expectant trio had come round the bend in the road they saw in front of them, walking alone, a young lady in a short tweed suit with hat to match.

The gown was of a peculiar shade of grey, and by her easy, swinging gait and the graceful carriage of her head Walter Fetherston instantly recognised that there before him, all unconscious of his presence, was the girl he believed to be still in Sicily--Enid Orlebar!

He looked again, to satisfy himself that he was not mistaken. Then, drawing back, lest her attention should be attracted by their footsteps, he motioned to his companions to retreat around the bend and thus out of her sight.

"Now," he said, addressing them, "there is some deep mystery here. That lady must not know we are here."

"You've recognised her, sir?" asked Summers, who had on several previous occasions a.s.sisted him.

"Yes," was the novelist's hard reply. "She is here with some mysterious object. You mustn't approach The Yews till dark."

"Mr. Bailey will then be at home, sir," remarked the sergeant. "I thought you wished to explore the place before he arrived?"

Walter paused. He saw that Enid could not be on her way to visit Bailey, if he were not at home. So he suggested that Summers, whom she did not know, should go forward and watch her movements, while he and the sergeant should proceed to the house of suspicion.

Arranging to meet later, the officer from Scotland Yard lit his pipe and strolled quickly forward around the bend to follow the girl in grey, while the other two halted to allow them to get on ahead.

"Have you ever seen that lady down here before, sergeant?" asked Walter presently.

"Yes, sir. If I don't make a mistake, it is the same lady who asked me the way to The Yews soon after Mr. Bailey took the house--the lady who came with the man whom she addressed as 'Doctor'!"

"Are you quite certain of this?"

"Not quite certain. She was dressed differently, in brown--with a different hat and a veil."

"They came only on that one occasion, eh?"

"Only that once, sir."

"But why, I wonder, is she going to The Yews? Pietro, you say, went up to London this morning?"

"Yes, sir, by the nine-five. And the house is locked up--she's evidently unaware of that."

"No doubt. She'll go there, and, finding n.o.body at home, turn away disappointed. She must not see us."

"We'll take good care of that, sir," laughed the local sergeant breezily, as he left his companion's side and crossed the road so that he could see the bend. "Why!" he exclaimed, "she ain't goin' to Asheldham after all!

She's taken the footpath to the left that leads into Steeple! Evidently she knows the road!"

"Then we are free to go straight along to The Yews, eh? She's making a call in the vicinity. I wonder where she's going?"

"Your friend will ascertain that," said the sergeant. "Let's get along to The Yews and 'ave a peep round."

Therefore the pair, now that Enid was sufficiently far ahead along a footpath which led under a high, bare hedge, went forth again down the high road until, after crossing the brook, they turned to the right into Asheldham village, where, half-way between that place and New Hall, they turned up a short by-road, a cul-de-sac, at the end of which a big, old-fashioned, red-brick house of the days of Queen Anne, half hidden by a belt of high Scotch firs, came into view.

Shut off from the by-road by a high, time-mellowed brick wall, it stood back lonely and secluded in about a couple of acres of well wooded ground. From a big, rusty iron gate the ill-kept, gravelled drive took a broad sweep up to the front of the house, a large, roomy one with square, inartistic windows and plain front, the ugliness of which the ivy strove to hide.

In the grey light of that wintry afternoon the place looked inexpressibly dismal and neglected. Years ago it had, no doubt, been the residence of some well-to-do county family; but in these twentieth-century post-war days, having been empty for nearly ten years, it had gone sadly to rack and ruin.

The lawns had become weedy, the carriage-drive was, in places, green with moss, like the sills of the windows and the high-pitched, tiled roof itself. In the centre of the lawn, before the house, stood four great ancient yews, while all round were high box hedges, now, alas! neglected, untrimmed and full of holes.

The curtains were of the commonest kind, while the very steps leading to the front door were grey with lichen and strewn with wisps of straw. The whole aspect was one of neglect, of decay, of mystery.

The two men, opening the creaking iron gate, advanced boldly to the door, an excuse ready in case Pietro opened it.

They knocked loudly, but there was no response. Their summons echoed through the big hall, causing Walter to remark:

"There can't be much furniture inside, judging from the sound."

"Four motor vanloads came here," responded the sergeant. "The first was in a plain van."

"You did not discover whence it came?"

"I asked the driver down at the inn at Southminster, and he told me that they came from the Trinity Furnishing Company, Peckham. But, on making inquiries, I found that he lied; there is no such company in Peckham."

"You saw the furniture unloaded?"

"I was about here when the first lot came. When the other three vans arrived I was away on my annual leave," was the sergeant's reply.

Again they knocked, but no one came to the door. A terrier approached, but he proved friendly, therefore they proceeded to make an inspection of the empty stabling and disused outbuildings.

Three old hen-coops were the only signs of poultry-farming they could discover, and these, placed in a conspicuous position in the big, paved yard, were without feathered occupants.

There were three doors by which the house could be entered, and all of them Walter tried and found locked. Therefore, noticing in the rubbish-heap some stray pieces of paper, he at once turned his attention to what he discovered were fragments of a torn letter. It was written in French, and, apparently, had reference to certain securities held by the tenant of The Yews.

But as only a small portion of the destroyed communication could be found, its purport was not very clear, and the name and address of the writer could not be ascertained.

Yet it had already been proved without doubt that the mysterious tenant of the dismal old place--the man who posed as a poultry-farmer--had had as visitors Dr. Weirmarsh and Enid Orlebar!

For a full half-hour, while the red-faced sergeant kept watch at the gate, Walter Fetherston continued to investigate that rubbish-heap, which showed signs of having been burning quite recently, for most of the sc.r.a.ps of paper were charred at their edges.
