"Like as not you're so brave you wouldn't mind goin' across the Fens," he said. "Them there flames wouldn't be scarin' such a 'ero as Mr. James Collins. Oh no! You'll find it a mile or so less than the three miles by road. It's the shortest cut, but I don't recommend it. 'Owever, that lies with you. I'll tell Sir Nigel where you're gone if 'e asks me, you may be sure!"

"Orl right! Across the Fens is the shortest, you says. Well, I'll try it ternight and see. You're right fer once. I ain't afraid. It tykes more'n twiddley little bits er lights ter scare James Collins, I tells yer. So long."

Borkins, standing at the window in the dining room and peering through the dusk at Collins' st.u.r.dy figure as it swung past him down the drive, bit his lip a moment, and made as if to go after him.

"No, I'll be danged if I do!" he said suddenly. "If 'e knows such a lot, well, let 'im take the risk. I warned 'im anyhow, so I've done my bit. The flames'll do the rest." And he laughed.

But James Collins did not come back, when he ought to have done, and the evening papers arrived before him, brought by the station-master's son Jacob. Jacob had seen nothing of Collins, and Merriton, who did not know that the man had gone on this errand, made no remark when the hours went slowly by, and no sign of Collins appeared.

At eleven o'clock the household retired. Merriton, still ignorant of his man's absence, went to bed and slept soundly. The first knowledge he received of Collins' absence was when Borkins appeared in his bedroom in the morning.

"Where the deuce is Collins?" Merriton said pettishly, for he did not like Borkins, and they both knew it.

"That's exactly what I 'ave been tryin' ter find out, sir," responded Borkins, bravely. "'E 'asn't been back since last night, so far as I could make out."

"Last night?" Merriton sat bolt upright in bed and ran his fingers through his hair. "What the d.i.c.kens do you mean?"

"Collins went out last night, sir, to fetch your papers. Leastways that was what he said he was goin' for," responded Borkins patiently, "and so far as I knows he 'asn't returned yet. Whether he dropped into a public 'ouse on the way or not, I don't know, or whether he took the short cut to the station across the Fens isn't for me to say. But-'e 'asn't come back yet, sir!"

Merriton looked anxious. Collins had a strong hold upon his master's heart. He certainly wouldn't like anything to happen to him.

"You mean to say," he said sharply, "that Collins went out last night to fetch my papers from the station and was fool enough to take the short cut across the Fens?"

"I warned him against doin' so," said Borkins, "since 'e said 'e'd probably go that way. That no Frozen Flames was a-goin' ter frighten 'im, an'-an' 'is language was most offensive. But I've no doubt 'e went."

"Then why the devil didn't you tell me last night?" exclaimed Merriton angrily, jumping out of bed. "You knew the-the truth about Mr. Wynne's disappearance, and yet you deliberately let that man go out to his death. If anything's happened to James Collins, Borkins, I'll-I'll wring your d.a.m.ned neck. Understand?"

Borkins went a shade or two paler, and took a step backward.

"Sir Nigel, sir-I-"

"When did Collins go?"

"'Arf past eight, sir!" Borkins' voice trembled a little. "And believe me or not, sir, I did my best to persuade Collins from doin' such an extremely dangerous thing. I begged 'im not to think o' doin' it, but Collins is pig-'eaded, if you'll forgive the word, sir, and he was bent upon gettin' your papers. I swear, sir, I ain't 'ad anythin' ter do with it, and when 'e didn't come back last night before I went to bed I said to meself, I said, 'Collins 'as dropped into a public 'ouse and made a-a a.s.s of hisself', I said. And thought no more about it, expectin' he'd be in later. But 'is bed 'asn't been slept in, and there 's no sign of 'im anywhere."

Merriton twisted round upon his heel and looked at the man keenly for a moment.

"I'm fond of Collins, Borkins," he said abruptly. "We've known each other a long time. I shouldn't like anything to happen to the chap while he's in my service, that's all. Get out now and make enquiries in every direction. Have Dimmock go down to the village. And ransack every public house round about. If you can't find any trace of him-" his lips tightened for a moment, "then I'll fetch in the police. I'll get the finest detective in the land on this thing, I'll get Cleek himself if it costs me every penny I possess, but I'll have him traced somehow. Those devilish flames are taking too heavy a toll. I've reached the end of my tether!"

He waved Borkins out with an imperious hand, and went on with his dressing, his heart sick. What if Collins had met with the same fate as Dacre Wynne? What were those fiendish flames, anyhow, that men disappeared completely, leaving neither sight nor sound? Surely there was some brain clever enough to probe the mystery of them.

"If Collins doesn't turn up this morning," he told himself as he shaved with a very unsteady hand, "I'll go straight up to London by the twelve o'clock train and straight to Scotland Yard. But I'll find him-d.a.m.n it, I'll find him."

But no trace of James Collins could be found. He was gone-completely. No one had seen him, no one but Borkins had known of his probable journey across the Fens at night-time, and Borkins excused himself upon the plea that Collins hadn't actually said he was going that way. He had simply vanished as Dacre Wynne had vanished, as Will Myers and all that long list of others had vanished. Eaten up by the flames-and in Twentieth Century England! But the fact remained. Dacre Wynne had disappeared, and now James Collins had followed him. And a new flame shone among the others, a newer, brighter flame than any before. Merriton saw it himself, that was the devilish part of it. His own eyes had seen the thing appear, just as he had seen it upon the night when Dacre Wynne had vanished. But he didn't shoot at it this time. Instead, he packed a small bag, ran over and said good-bye to 'Toinette and told her he was going to have a day in town, but told her nothing else. Then he took the twelve o'clock train to town. A taxi whisked him to Scotland Yard.

CHAPTER X

-AND THE LADY

And this was the extraordinary chain of events which brought young Merriton into Mr. Narkom's office that day while Cleek was sitting there, and on being introduced as "Mr. Headland" heard the story from Sir Nigel's lips.

As he came to the last "And no trace of either body has ever been found," Cleek suddenly switched round in his chair and exclaimed:

"An extraordinary rigmarole altogether!" Meeting Merriton's astonished eyes with his own keen ones, he went on: "The flames, of course, are a plant of some sort. That goes without saying. But the thing to find out is what they're there for to hide. When you've discovered that, you'll have got half way to the truth, and the rest will follow as a matter of course.... What's that, Mr. Narkom? Yes, I'll take the case, Sir Nigel. My name's Cleek-Hamilton Cleek, at your service. Now let's hear the thing all over again, please. I've one or two questions I'd like to ask."

Merriton left Scotland Yard an hour later, lighter in heart than he had been for some time-ever since, in fact, Dacre Wynne's tragic disappearance had cast such a gloom over his life's happiness. He had unburdened his soul to Cleek-absolutely. And Cleek had treated the confession with a decent sort of respect which was enough to win any chap over to him. Merriton in fact had found in Cleek a friend as well as a detective. He had been a little astonished at his general get-up and appearance, but Merriton had heard of his peculiar birthright, and felt that the man himself was capable of almost anything. Certainly he proved full of sympathetic understanding.

Cleek understood the ground upon which he stood with regard to his friendship with Dacre Wynne. He had, with a wonderful intuition, sensed the peculiar influence of the man upon Nigel-this by look and gesture rather than by use of tongue and speech. And Cleek had already drawn his own conclusions. He heard of Nigel's engagement to Antoinette Brellier, and of how Dacre Wynne had taken it, heard indeed all the little personal things which Merriton had never told to any man, and certainly hadn't intended telling to this one.

But that was Cleek's way. He secured a man's confidence and by that method got at the truth. A bond of friendship had sprung up between them, and Cleek and Mr. Narkom had promised that before a couple of days were over, they would put in an appearance at Fetchworth, and look into things more closely. It was agreed that they were to pose as friends of Sir Nigel, since Cleek felt that in that way he could pursue his investigations unsuspected, and make more headway in the case.

But there was but one thing Nigel hadn't spoken of, and that was the very foolish and ridiculous action of his upon that fateful evening of the dinner party. Only he and Doctor Bartholomew-who was as close-mouthed as the devil himself over some things-knew of the incident of the pistol-shooting, so far as Merriton was aware. And the young man was too ashamed of the whole futile affair and what it very apparently proved to the listener-that he had certainly drunk more than was good for him-to wish any one else to share in the absurd little secret. It could have no bearing upon the affair, and if 'Toinette got to hear of it, well, he'd look all sorts of a fool, and possibly be treated to a sermon-a prospect which he did not relish in the slightest.

As he left the Yard and turned into the keen autumn sunshine, he lifted his face to the skies and thanked the stars that he had come to London after all and placed things in proper hands. There was nothing now for him to do but to go back to Merriton Towers and as expeditiously as possible make up for the day lost from 'Toinette.

So, after a visit to a big confectioners in Regent Street, and another to a little jeweller in Piccadilly, Merriton got into the train at Waterloo, carrying his parcels With a happy heart. He got out at Fetchworth station three hours later, hailed the only hack that stood there-for he had forgotten to apprise any one at the Towers of his quick return-and drove straightway to Withersby Hall.

'Toinette was at the window as he swung open the great gate. When she saw him she darted away and came flying down the drive to meet him.

The contents of the various packages made her happy as a child, and it was some time after they reached the house that Nigel asked some question concerning her uncle.

Her face clouded ever so little, and for the first time Nigel noticed that she was pale.

"Uncle has gone away for a few days," she replied. "He said it was business-what would you? But I told him I should be lonesome in this great house, and I-I am so frightened at those horrible little flames that twinkle twinkle all night long. I cannot sleep when I am alone, Nigel. I am a baby I know, but I cannot help it. It makes me feel so afraid!"

As was usual in moments of emotion with 'Toinette, her accent became more p.r.o.nounced. He stroked her hair with a gentle hand, as though she were in very truth the child she tried not to be.

"Poor little one! I wish I could come across and put up here for the night. Hang conventions, anyway! And then too I have to make ready for some visitors who will be down to-morrow or the next day."

"Visitors, Nigel?"

"Yes, dear. I've a couple of-friends coming to spend a short time with me. Chaps I met in London to-day."

"What did you go up for, Nigel-really?"

He coloured a little, and was thankful that she turned away at that moment to straighten the collar of her blouse. He didn't like lying to the woman he was going to marry. But he had given his word to Cleek.

"Oh," he said off-handedly, "I-I went to my tailor's. And then stepped in to buy you that little trinket and your precious chocs, and came along home again. Met these fellows on my way across town. Rather nice chaps-one of 'em, anyhow. Used to know some friends of friends of his, girl called Ailsa Lorne. And the other one happened to be there so I asked him, too. They won't worry you much, 'Toinette. They're frightfully keen about the country, and will be sure to go out shootin' and snuffin' round like these town johnnies always do when they get in places like this.... Well, as Mr. Brellier isn't here I suppose I'd better be making my way home again. Wish we were married, 'Toinette. There'd be no more of these everlasting separations then. No more nightmares for you, little one. Only happiness and joy, and-and heaps of other rippin' things. Never mind, we'll make it soon, won't we?"

She raised her face suddenly and her eyes met his. There was a haunted look in them that made him draw closer, his own face anxious.

"What is it, dear?" he said in a low, worried tone.

"Only-Dacre Wynne. Always Dacre Wynne these days," she replied unsteadily. "Do you know, Nigel, I am a silly girl, I know, but somehow I dare not think of marriage with you until-everything is finally cleared up, and his death or disappearance, or whatever the dreadful affair was, discovered. I feel in some inexplicable way responsible. It is as if his spirit were standing between us and our happiness. Tell me I am foolish, please."

"You are more than foolish," said Nigel obediently, and laughed carelessly to show her how he treated the thing. But in his heart he knew her feelings, knew them and fully understood. It was exactly as he had felt about it also. The bond that bound Dacre Wynne's life to his had not yet been snapped, the mystery of his disappearance seemed only to strengthen it. He wondered dully when he would ever feel free again, and then laughed inwardly at himself for making a farce of the whole thing, for building a mountain out of a stupid little molehill. And 'Toinette was helping him. They were both unutterably foolish. Anyhow, Cleek was coming soon to clear matters up. He wished with all his heart that he might tell 'Toinette, and thus relieve the tension of her mind, but he had given his word to Cleek, and with a man of his type his word was sacred.

So he kissed her good-bye and laughed, and went back to Merriton Towers to prepare for their coming. But the cloud had dropped across his horizon again, and the sun was once more obscured. There was no smile upon his lips as he clanged the great front door to behind him.
