"What should I want him for?" growled Dunn, more and more disconcerted, as he saw that he was not playing his part too well.

"I don't know," she answered. "I suppose you do."

"You suppose a lot," he retorted roughly. "Now you listen to me. I don't want to hurt you, but I don't mean to be interfered with. I'm going over the house to see what I can find that's worth taking. Understand?"

"Oh, perfectly," she said.

She was watching him closely, and she noticed that he still made no attempt to take possession of her jewellery, though it lay at his hand, and that puzzled her very much, indeed, for she supposed the very first thing a burglar did was always to seize such treasures as these of hers.

But this man paid them no attention whatever, and did not even notice them.

He was feeling in his pockets now and he took out the revolver and the coil of thin rope he had secured from the burglar.

"Now, do you know what I'm going to do?" he asked, with an air of roughness and brutality that was a little overdone. He put the revolver and the rope down on the bed, the revolver quite close to her.

"I'm going," he continued, "to tie you up to one of those chairs. I can't risk your playing any tricks or giving an alarm, perhaps, while I'm searching the house. I shall take what's worth having, and then I shall clear off, and if your stepfather's coming home tonight you won't have to wait long till he releases you, and if he don't come I can't help it."

He turned his back to her as he spoke and took hold of one of the chairs in the room, and then of another and looked at them as though carefully considering which would be the best to use for the carrying out of his threat.

He appeared to find it difficult to decide, for he kept his back turned to her for two or three minutes, during all of which time the revolver lay on the bed quite close to her hand.

He listened intently for he fully expected her to s.n.a.t.c.h it up, and he wished to be ready to turn before she could actually fire. But, indeed, nothing was further from her thoughts, for she did not know in the least how to use the weapon or even how to fire it off, and the very thought of employing it to kill any one would have terrified her far more even than had done her experiences of this night.

So the pistol lay untouched by her side, while, very pale and trembling a little, she waited what he would do, and on his side he felt as much puzzled by her failure to use the opportunity he had put in her way as she was puzzled by his neglect to seize her jewellery lying ready to his hand.

He was still hesitating, still appearing unable to decide which chair to employ in carrying out his proclaimed purpose of fastening her up when she asked a question that made him swing round upon her very quickly and with a very startled look.

"Are you a real burglar?" she said.

CHAPTER VI. A DISCOVERY

"What do you mean?" Dunn asked quickly. The matted growth of hair on his face served well to hide any change of expression, but his eyes betrayed him with their look of surprise and discomfiture, and in her own clear and steady glance appeared now a kind of puzzled mockery as if she understood well that all he did was done for some purpose, though what that purpose was still perplexed her.

"I mean," she said slowly, "well--what do I mean? I am only asking a question. Are you a burglar--or have you come here for some other reason?"

"I don't know what you're getting at," he grumbled. "Think I'm here for fun? Not me. Come and sit on this chair and put your hands behind you and don't make a noise, or scream, or anything, not if you value your life."

"I don't know that I do very much," she answered with a manner of extreme bitterness, but more as if speaking to herself than to him.

She did as he ordered, and he proceeded to tie her wrists together and to fasten them to the back of the chair on which she had seated herself.

He was careful not to draw the cords too tight, but at the same time he made the fastening secure.

"You won't disturb mother, will you?" she asked quietly when he had finished. "Her room's the one at the end of the pa.s.sage."

"I don't want to disturb any one," he answered. "I only want to get off quietly. I won't gag you, but don't you try to make any noise, if you do I'll come back. Understand?"

"Oh, perfectly," she answered. "May I ask one question? Do you feel very proud of yourself just now?"

He did not answer, but went out of the room quickly, and he had an impression that she smiled as she watched him go, and that her smile was bitter and a little contemptuous.

"What a girl," he muttered. "She scored every time. I didn't find out a thing, she didn't do anything I expected or wanted her to. She seemed as if she spotted me right off--I wonder if she did? I wonder if she could be trusted?"

But then he thought of that photograph on the mantelpiece and his look grew stern and hard again. He was careful to avoid the room the girl had indicated as occupied by her mother, but of all the others on that floor he made a hasty search without discovering anything to interest him or anything of the least importance or at all unusual.

From the wide landing in the centre of the house a narrow stairway, hidden away behind an angle of the wall so that one did not notice it at first, led above to three large attics with steeply-sloping roofs and evidently designed more for storage purposes than for habitation.

The doors of two of these were open and within was merely a collection of such lumber as soon acc.u.mulates in any house.

The door of the third attic was locked, but by aid of the jemmy he still carried, he forced it open without difficulty.

Within was nothing but a square packing-case, standing in the middle of the floor. Otherwise the light of the electric torch he flashed around showed only the bare boarding of the floor and the bare plastered walls.

Near the packing-case a hammer and some nails lay on the floor and the lid was in position but was not fastened, as though some interruption had occurred before the task of nailing it down could be completed.

Dunn noted that one nail had been driven home, and he was on the point of leaving the attic, for he knew he had not much time and hoped that downstairs he would be able to make some discoveries of importance, when it occurred to him that it might be wise to see what was in this case, the nailing down the lid of which had not been completed.

He crossed the room to it, and without drawing the one nail, pushed back the lid which pivoted on it quite easily.

Within appeared a covering of coa.r.s.e sacking. He pulled this away with a careless hand, and beneath the beam of his electric torch showed the pale and dreadful features of a dead man--of a man, the center of whose forehead showed the small round hole where a bullet had entered in; of a man whose still-recognizable features were those of the photograph on the mantel-piece of the room downstairs, the photograph that was signed:

"Devotedly yours, Charley Wright."

For a long time Robert Dunn stood, looking down in silence at that dead face which was hardly more still, more rigid than his own.

He shivered, for he felt very cold. It was as though the coldness of the death in whose presence he stood had laid its chilly hand on him also.

At last he stirred and looked about him with a bewildered air, then carefully and with a reverent hand, he put back the sackcloth covering.

"So I've found you, Charley," he whispered. "Found you at last."

He replaced the lid, leaving everything as it had been when he entered the attic, and stood for a time, trying to collect his thoughts which the shock of this dreadful discovery had so disordered, and to decide what to do next.

"But, then, that's simple," he thought. "I must go straight to the police and bring them here. They said they wanted proof; they said I had nothing to go on but bare suspicion. But that's evidence enough to hang Deede Dawson--the girl, too, perhaps."

Then he wondered whether it could be that she knew nothing and was innocent of all part or share in this dreadful deed. But how could that be possible? How could it be that such a crime committed in the house in which she lived could remain unknown to her?

On the other hand, when he thought of her clear, candid eyes; when he remembered her gentle beauty, it did not seem conceivable that behind them could lie hidden the tigerish soul of a murderess.

"That's only sentiment, though," he muttered. "Nothing more. Beautiful women have been rotten bad through and through before today. There's nothing for me to do but to go and inform the police, and get them here as soon as possible. If she's innocent, I suppose she'll be able to prove it."

He hesitated a moment, as he thought of how he had left her, bound and a prisoner.

It seemed brutal to leave her like that while he was away, for he would probably be some time absent. But with a hard look, he told himself that whatever pain she suffered she must endure it.

His first and sole thought must be to bring to justice the murderers of his unfortunate friend; and to secure, too, thereby, the success almost certainly of his own mission.
