Finally he was deposited in a chair, and as he raised his hand to the scarf, which toward the end of the journey had been bound more tightly about his head so as to prevent him from seeing at all, he heard a door closed and locked.

The scarf was quickly removed. And Dan found himself in a low- ceilinged attic having a sloping roof and one shuttered window. A shadeless electric lamp hung from the ceiling. Excepting the cane-seated chair in which he had been deposited and a certain amount of nondescript lumber, the attic was unfurnished. Dan rapidly considered what his father would have done in the circumstances.

"Make sure that the door is locked," he muttered.

He tried it, and it was locked beyond any shadow of doubt.

"The window."

Shutters covered it, and these were fastened with a padlock.

He considered this padlock attentively; then, drawing from his pocket one of those wonderful knives which are really miniature tool-chests, he raised from a grove the screw-driver which formed part of its equipment, and with neatness and dispatch unscrewed the staple to which the padlock was attached!

A moment later he had opened the shutters and was looking out into the drizzle of the night.

The room in which he was confined was on the third floor of a dingy, brick-built house; a portion of some other building faced him; down below was a stone-paved courtyard. To the left stood a high wall, and beyond it he obtained a glimpse of other dingy buildings. One lighted window was visible-a square window in the opposite building, from which amber light shone out.

Somewhere in the street beyond was a standard lamp. He could detect the halo which it cast into the misty rain. The glass was very dirty, and young Kerry raised the sash, admitting a draught of damp, cold air into the room. He craned out, looking about him eagerly.

A rainwater-pipe was within reach of his hand on the right of the window and, leaning out still farther, young Kerry saw that it passed beside two other, larger, windows on the floor beneath him. Neither of these showed any light.

Dizzy heights have no terror for healthy youth. The brackets supporting the rain-pipe were a sufficient staircase for the agile Dan, a more slippery prisoner than the famous Baron Trenck; and, discarding his muffler and his Burberry, he climbed out upon the sill and felt with his thick-soled boots for the first of these footholds. Clutching the ledge, he lowered himself and felt for the next.

Then came the moment when he must trust all his weight to the pipe. Clenching his teeth, he risked it, felt for and found the third angle, and then, still clutching the pipe, stood for a moment upon the ledge of the window immediately beneath him. He was curious respecting the lighted window of the neighbouring house; and, twisting about, he bent, peering across-and saw a sight which arrested his progress.

The room within was furnished in a way which made him gasp with astonishment. It was like an Eastern picture, he thought. Her golden hair dishevelled and her hands alternately clenching and unclenching, a woman whom he considered to be most wonderfully dressed was pacing wildly up and down, a look of such horror upon her pale face that Dan's heart seemed to stop beating for a moment!

Here was real trouble of a sort which appealed to all the chivalry in the boy's nature. He considered the window, which was glazed with amber-coloured glass, observed that it was sufficiently open to enable him to slip the fastening and open it entirely could he but reach it. And-yes!-there was a rain- pipe!

Climbing down to the yard, he looked quickly about him, ran across, and climbed up to the lighted window. A moment later he had pushed it widely open.

He was greeted by a stifled cry, but, cautiously transferring his weight from the friendly pipe to the ledge, he got astride of it, one foot in the room. Then, by exercise of a monkey-like agility, he wriggled his head and shoulders within.

"It's all right," he said softly and reassuringly; "I'm Dan Kerry, son of Chief Inspector Kerry. Can I be of any assistance?"

Her hands clasped convulsively together, the woman stood looking up at him.

"Oh, thank God!" said the captive. "But what are you going to do? Can you get me out?"

"Don't worry," replied Dan confidently. "Father and I can manage it all right!"

He performed a singular contortion, as a result of which his other leg and foot appeared inside the window. Then, twisting around, he lowered himself and dropped triumphantly upon a cushioned divan. At that moment he would have faced a cage full of man-eating tigers. The spirit of adventure had him in its grip. He stood up, breathing rapidly, his crop of red hair more dishevelled than usual.

Then, before he could stir or utter any protest, the golden- haired princess whom he had come to rescue stooped, threw her arms around his neck, and kissed him.

"You darling, brave boy!" she said. "I think you have saved me from madness."

Young Kerry, more flushed than ever, extricated himself, and:

"You're not out of the mess yet," he protested. "The only difference is that I'm in it with you!"

"But where is your father?"

"I'm looking for him."

"What!"

"Oh! he's about somewhere," Dan assured her confidently.

"But, but-" She was gazing at him wide-eyed, "Didn't he send you here?"

"You bet he didn't," returned young Kerry. "I came here on my own accord, and when I go you're coming with me. I can't make out how you got here, anyway. Do you know whose house this is?"

"Oh, I do, I do!"

"Whose?"

"It belongs to a man called Chada."

"Chada? Never heard of him. But I mean, what part of London is it in?"

"Whatever do you mean? It is in Limehouse, I believe. I don't understand. You came here."

"I didn't," said young Kerry cheerfully; "I was fetched!"

"By your father?"

"Not on your life. By a couple of Chinks! I'll tell you something." He raised his twinkling blue eyes. "We are properly up against it. I suppose you couldn't climb down a rain-pipe?"

VII. RETRIBUTION

It was that dark, still, depressing hour of the night, when all life is at its lowest ebb. In the low, strangely perfumed room of books Zani Chada sat before his table, his yellow hands clutching the knobs on his chair arms, his long, inscrutable eyes staring unseeingly before him.

Came a disturbance and the sound of voices, and Lou Chada, his son, stood at the doorway. He still wore his evening clothes, but he no longer looked smart. His glossy black hair was dishevelled, and his handsome, olive face bore a hunted look. Panic was betoken by twitching mouth and fear-bright eyes. He stopped, glaring at his father, and:

"Why are you not gone?" asked the latter sternly. "Do you wish to wreck me as well as yourself?"

"The police have posted a man opposite Kwee's house. I cannot get out that way."

"There was no one there when the boy was brought in."

"No, but there is now. Father!" He took a step forward. "I'm trapped. They sha'n't take me. You won't let them take me?"

Zani Chada stirred not a muscle, but:

"To-night," he said, "your mad passion has brought ruin to both of us. For the sake of a golden doll who is not worth the price of the jewels she wears, you have placed yourself within reach of the hangman."

"I was mad, I was mad," groaned the other.

"But I, who was sane, am involved in the consequences," retorted his father.

"He will be silent at the price of the boy's life."

"He may be," returned Zani Chada. "I hate him, but he is a man. Had you escaped, he might have consented to be silent. Once you are arrested, nothing would silence him."

"If the case is tried it will ruin Pat's reputation."

"What a pity!" said Zani Chada.
