Jim's hand as he had crawled forward, clutched the foot of a man who was in hiding in this selfsame clump of bushes. James acted instantly, realizing instinctively the danger, the extreme danger of the situation. He leaped forward for the man's throat and to his utter surprise the body lay perfectly limp.

"Great Heavens!" he exclaimed, "this man is dead."

"It's the poor fellow from the gully, below," said the engineer, after an examination; "there's no mistaking him."

"But how did he get here?" questioned Jim, with suppressed excitement and alarm.

"That's simple," replied his friend. "These bandits who live here, brought the body up at the first convenient chance and left it here for the time being, but they may come for it any time so we had better be on the lookout for trouble.

"We don't have to; it is always on the lookout for us," replied Jim briefly and with truth.

"There's someone directly ahead," remarked the engineer, "or I miss my guess."

"Just wait a minute, Chief," said Jim; "I want to size up this castle before making the next move."

"You don't observe any anxiety on my part to go anywhere do you, Captain?" questioned Berwick.

"Quiet as a kitten," replied Jim with a grin, and then without any further remarks, he crawled past the form of the unfortunate man, until he reached the edge of the copse, and gathering a low bush around his shoulders so that he appeared to be a part of the natural scenery himself, he observed the castle closely with the eye of a trained scout.

The fog was rifted by the wind so that he could see with sufficient clearness the outlines and details of the high brick castle. As has been said, they were on the north side, where there was the large stained glass window that lit the grand staircase, and now shone with a faint radiance.

There was also a line of broad mullioned windows, their round, thick glass in circles of lead, gleaming like opals when the full light was within, but now cold and ghostly in the dimness of the fog-laden night. These windows were some twenty feet from the ground, and Jim's keen eyes regarded them with special interest. Further along and somewhat lower were the smaller windows, evidently of the kitchen, and near the ground several more heavily barred.

After a few minutes of observation, Jim returned to his companion, his mind fully made up.

"Well, James, what do you make of it?" queried his friend.

"I'll make more of it a little later," replied Jim; "I'm going to move on the enemy, right away."

"Very well, I'm ready," remarked the engineer. "When you can't go back with safety or stand still it is a good scheme to go forward."

"But I want you to wait here, John," explained Jim; "there's much less chance with two than one. In case I need you I'll yell."

"If you don't happen to be gagged," replied his friend cheerfully.

"Never you fear about that," returned Jim confidently; "there's none of that gang that is going to get me so quick but that there will be something doing on my part first."

"Nothing surer than that," replied the engineer heartily. "Luck to you, Jim," gripping his hand, "and I'll be in reserve here when you want me."

"Good old Chief," said Jim, returning his friend's grip; "now I'm off."

Without any further words Jim crawled to the edge of the thicket, leaving John Berwick in the grewsome company of the dead man, but Berwick took up a position where he could see the tall, shadowy figure of James Darlington as he advanced straight toward the stronghold of this gang of unmerciful pirates.

"That boy has them all beaten when it comes to unqualified nerve," muttered the engineer to himself; "the best fellow in an emergency I ever saw, and that's something."

James would have felt proud to have heard his friend's eulogy, but his mind was fully taken up with the problem he was facing. He must get into that house without delay; to stand long where he was meant sure detection in a short time. If he had only possessed his revolver, he would have felt more comfortable.

"Have to get or borrow a gun from one of those chaps inside there," he mused with shrewd humor.

He was now directly below the long mullioned window, but as he was not a little birdie with wings, he could not fly, and had to climb.

"Here's luck," he said; "this vine is bigger than I thought it could be. Takes California to grow a vine like a tree and that's a fact."

Indeed, the vine that spread its dark green splendor over the whole north side of the great structure and wrapped itself around the giant chimney had a stem that was more like the trunk of a small tree and very tough and fibrous. Jim did not hesitate, but quickly removed his shoes, and with both free hands, noiselessly climbed up towards the window, sustaining his weight partially on the rough jutting bricks until he finally reached in safety the broad sill of the mullioned window.

"So far so good," he murmured, "now to get inside."

Very slowly and cautiously he pushed on the lower part of the center window and it gave easily enough, the gang in foolhardy security never dreaming that an enemy would dare approach their stronghold, much less come into their very castle. Indeed, their confidence was in some measure justified, for their head and chief, old Captain Broome, was very powerful through this section, had strong friends among the officials in the city and was safe from being bothered by the authorities. As for private enemies, he could very well take care of them himself.

So without any trouble at this point Jim slipped through the window and was within the castle of his bitterest enemy. He let himself down from the window, to a settee, and thence to the floor. By the dim light from the windows he saw that he was in a long, rectangular-shaped room, evidently lined with bookcases, and in the dimness at one end loomed the outline of a huge fireplace. For the moment Jim felt a thrill of excitement go through him. There was something in the fact that he was alone and unarmed in the house of his foes, quite enough to give him this sensation.

Suppose that you were standing in the darkness in a cage where some lions were stretched out asleep but liable to awake at any moment, you might be excused if you had a few shivery thrills, and so it was with Jim.

It was evident that this room was not in general use and our adventurer could not have chosen a better place to land as it were.

He stopped only long enough for his eyes to become accustomed to the lack of light and then he made sure that there was nothing in the room that would serve him for a weapon.

"Might take a dictionary and throw some of the hard words at 'em," he remarked with his usual humorous twist of imagination when in a tight place.

Then he cautiously opened a door which led into a long, wide corridor that was decidedly dark, except at the further end, where shone a faint light. Keeping close to the wall, he went softly along until he came to the main staircase, which surprised Jim with the winding sweep of its magnificence and the beautiful stained glass window above it. But there was that in the large hall below that made him draw back.

There was stretched out on an immense rug, the other hound, his nose between his paws and his watchful, red-rimmed eyes upon the great door leading from the hall to the out-of-doors. No wonder that the sight of him made Jim pause and draw back into the darkness of the upper corridor. One suspicion, and the huge beast would take the staircase in three leaps, and neither quickness, strength nor prowess could have saved Jim if once the hound had caught his trail.

"Gosh, I've got to find a weapon somewhere!" Jim mumbled to himself; "this won't do at all."

By this time his eyes had become thoroughly accustomed to the dim light and as he turned back he stopped and his heart beat with something almost akin to fright. Now our friend James Darlington was not superstitious by nature, but if that dim, silvery white figure was not a ghost, what in Sam Hill could it be?

It stood perfectly quiet to one side and about half way down the hall, evidently looking straight at Jim, but making no move to attack him. What was Jim to do? He could not retreat down the staircase to the main door, for that was to fall into the jaws of the hound. Neither could he reach the library in safety.
