"The mate's sure this time," Deede Dawson declared. "It's our turn to move, and whatever reply the other side makes, we're sure of our mate next move. By the way, did you ever solve that problem I showed you the other day?"

"Yes, I think so," answered Dunn. "It was a long time before I could hit on the right move, but I managed it at last, I think."

"Come and show me, then," said Deede Dawson, bustling back into his room and beginning to set up the pieces on his travelling chess-board. "This was the position, wasn't it? Now, what's your move?"

Dunn showed him, and Deede Dawson burst into a laugh that had in it for once a touch of honest enjoyment.

"Yes, that would do it, but for one thing you haven't noticed," he said.

"Black can push the p.a.w.n at KB7 and make it, not a queen, but a knight, giving check to your king and no mate for you next move."

"Yes, that's so," agreed Dunn. "I hadn't thought of that."

"Unexpected, eh? Making the p.a.w.n a knight?" smiled Deede Dawson. "But in chess, and in life, it's the unexpected you have to look out for."

"That's quite an aphorism," said Dunn. "It's true, too."

He went up to bed, but did not sleep well, and when at last he fell into a troubled slumber, it seemed to him that Charley Wright and John Clive were there, one on each side of him, and that they had come, not because they sought for vengeance, but because they wished to warn him of a doom like their own that they could see approaching but he could not.

Toward's morning he got an hour's sound rest, and he was down stairs in good time. He did not see Ella, but he heard her moving about, so knew that she was safe as yet; and Deede Dawson gave him some elaborate parting instructions, a little money, and a loaded revolver.

"I don't know that I want that," said Dunn. "My hands will be all I need once I'm face to face with Rupert Dunsmore."

"That's the right spirit," said Deede Dawson approvingly. "But the pistol may be useful too. You needn't use it if you can manage without, but you may as well have it. Good-bye, and the best of luck. Take care of yourself, and don't lose your head or do anything foolish."

"Oh, you can trust me," said Dunn.

"I think I can," smiled Deede Dawson. "I think I can. Good-bye. Be careful, avoid noise and fuss, don't be seen any more than you can help, and if you shoot, aim low."

"There's a vade mec.u.m for the intending a.s.sa.s.sin," Dunn thought grimly to himself, but he said nothing, gave the other a sullen nod, and started off on his strange and weird mission of murdering himself.

He found himself wondering if any one else had ever been in such a situation. He did not suppose so.

CHAPTER XXV. THE UNEXPECTED

To the very letter Dunn followed the careful and precise instructions given him by Deede Dawson, for he did not wish to rouse in any way the slightest suspicion or run the least risk of frightening off that unknown instigator of these plots who was, it had been promised him, to be present near Brook Bourne Spring at four that afternoon.

Even the thought of Ella was perhaps less clear and vivid to his mind just now than was his intense and pa.s.sionate desire to discover the ident.i.ty of the strange and sinister personality against whom he had matched himself.

"Very likely it's some madman," he thought to himself. "How in the name of common sense can he expect to inherit the t.i.tle and estates quietly after such a series of crimes as he seems to contemplate? Does he think no one will have any suspicion of him when he comes forward? Even if he is successful in getting rid of all of us in this way, how does he expect to be able to reap his reward? Of course he may think that there will be no direct evidence if he manages cleverly enough, and that mere suspicion he will be able to disregard and live down in time, but surely it will be plain enough that 'who benefits is guilty'? The whole thing is mad, fantastic. Why, the mere fact of any one making a claim to the t.i.tle and estates would be almost enough to justify a jury in returning a verdict of guilty."

But though his thoughts ran in this wise all the time he was journeying to London, and though he repeated them to himself over and over again, none the less there remained an uneasy consciousness in his mind that perhaps these people had plans more subtle than he knew, and that even this difficulty of making their claim without bringing instant suspicion on themselves they had provided for.

It was late in the year now, but the day was warm and very calm and fine. At the London terminus where he alighted he had a strong feeling that he was watched, and when he took the train back to Delsby he still had the idea that he was being kept under observation.

He felt he had been wise in deciding to carry out Deede Dawson's instructions so closely, for he was sure that if he had failed to do so in any respect alarm would have been taken at once, and warning telegrams gone flying on the instant to all concerned. Then that self-baited trap at Brook Bourne Spring, wherein he hoped to see his enemy taken, would remain unapproached, and all his work and risk would have gone for nothing.

When he alighted at his destination he was a little before time, and so he got himself something to eat at a small public-house near the station before starting on his fifteen-mile walk across country. Though he was not sure, he did not think any one was observing him now. Most likely his movements up to the present had appeared satisfactory, and it had not been thought necessary to watch him longer.

But he was careful to do nothing to rouse suspicion if he were still being spied upon, and after he had eaten and had a smoke he started off on his long tramp.

Even yet he was careful, and so long as he was near the village he made a show of avoiding observation as much as possible. Later on, when he had made certain he was not being followed, he did not trouble so much, though he still kept it in mind that any one he met or pa.s.sed might well be in fact one of Deede Dawson's agents.

He walked on sharply through the crisp autumn air, and in other circ.u.mstances would have found the walk agreeable enough. It was a little curious that as he proceeded on his way his chief preoccupation seemed to shift from his immediate errand and intense eagerness to discover the ident.i.ty of his unknown foe, with whom he hoped to stand face to face so soon, to a troubled and pressing anxiety about Ella.

Up till now he had not thought it likely that she was in the least real danger. He knew Simmonds, the man Walter had promised to put on watch at Bittermeads, and knew him to be capable and trustworthy. None the less, his uneasiness grew and strengthened with every mile he traversed, till presently her situation seemed to him the one weak link in his careful plans.

That the trap the unknown had so carefully laid for himself to be taken in, would a.s.suredly and securely close upon him, Dunn felt certain enough. Walter would see to that. Sure was it, too, that the enterprise Deede Dawson had planned for himself and Allen at the Abbey must result in their discomfiture and capture. Walter would see to that also. But concerning Ella's position doubt would insist on intruding, till at last he decided that the very moment the Brook Bourne Spring business was satisfactorily finished with he would hurry at his best speed to Bittermeads and make sure of her safety.

Absorbed in these uneasy thoughts, he had insensibly slackened speed, and looking at his watch he saw that it was two o'clock, and that he was still, by the milestone at the roadside, eight miles from his destination.

He wished to be there a little before the time arranged for him by Deede Dawson, and he increased his pace till he came to a spot where the path he had to take branched off from the road he had been following. At this spot a heavy country lad was sitting on a gate by the wayside, and as Dunn approached he clambered heavily down and slouched forward to meet him.

"Be you called Robert Dunn, mister?" he asked.

Dunn gave him a quick and suspicious look, much startled by this sudden recognition in so lonely a spot.

"Yes, I am," he said, after a moment's hesitation. "Why?"

"If you are, there's this as I'm to give you," the lad answered, drawing a note from his pocket.

"Oh, who gave you that?" Dunn asked, fully persuaded the note contained some final instructions from Deede Dawson and wondering if this lad were one of his agents in disguise, or merely some inhabitant of the district hired for the one purpose of delivering the letter.

But the lad's drawled reply disconcerted him greatly.

"A lady," he said. "A real lady in a big car, she told me to wait here and give you this. All alone she was, and drove just like a man."

He handed the letter over as he spoke, and Dunn saw that it was addressed to him in his name of Robert Dunn in Ella's writing. He blinked at it in very great surprise, for there was nothing he expected less, and he did not understand how she knew so well where he would be or how she had managed to get away from Bittermeads uninterfered with by Deede Dawson.

His first impulse was to suspect some new trap, some new and cunning trap that, perhaps, the unconscious Ella was being used to bait. Taking the letter from the boy, he said:

"How did you know it was for me?"

"Lady told me," answered the boy grinning. "She said as I was to look out for a chap answering to the name of Robert Dunn, with his face so covered with hair you couldn't see nothing of it no more'n you can see a sheep's back for wool. 'As soon as I set eye on 'ee,' says I, 'That's him,' I says, and so 'twas."

He grinned again and slouched away and Dunn stood still, holding the letter in his hand and not opening it at first. It was almost as though he feared to do so, and when at last he tore the envelope open it was with a hand that trembled a little in spite of all that he could do.

For there was something about this strange communication and the means adopted to deliver it to him that struck him as ominous in the extreme.

Some sudden crisis must have arisen, he thought, and it appeared to him that Ella's knowledge of where to find him implied a knowledge of Deede Dawson's plans that meant she was either his willing and active agent and accomplice, or else she had somehow acquired a knowledge of her stepfather's proceedings that must make her position a thousand times more critical and dangerous than before.

He flung the envelope aside and began to read the contents. It opened abruptly, without any form of address, and it was written in a hand that showed plain signs of great distress and agitation: "You are in great danger. I don't know what. I heard them talking. They spoke as though something threatened you, something you could not escape. Be careful, very careful. You asked me once if I had ever heard a man with a high, squeaky voice, and I did not answer. It was to a man with a voice like that I gave the packing-case I took away from here the night you came.

Do you remember? He was here all last night, I think. I saw him go very early. He is Mr. Walter Dunsmore. I saw him that day at Wreste Abbey, and I knew I had seen him before. This morning I recognized him. I am sure because he hurt his hand on the packing-case lid, and I saw the mark there still. He and my stepfather were talking all night, I think I couldn't hear everything. There is a General Dunsmore. Something is to happen to him at three o'clock and then to you later, and they both laughed a great deal because they think you will be blamed for whatever happens to General Dunsmore. He is to be enticed somewhere to meet you, but you are not to be there till four, too late. I am afraid, more afraid than ever I have been. What shall I do? I think they are making plans to do something awful. I don't know what to do. I think my stepfather suspects I know something, he keeps looking, looking, smiling all the time. Please come back and take mother and me away, for I think he means to kill us both."

There was no signature, but written like an afterthought across one corner of the note were the scribbled words:

"You told me something once, I don't know if you meant it." And then, underneath, was the addition--"He never stops smiling."

Twice over Dunn read this strange, disturbing message, and then a third time, and he made a little gesture of annoyance for it did not seem to him that the words he read made sense, or else it was that his brain no longer worked normally, and could not interpret them.
