“He must be making for whatever spot it is in England that is the center of the Brotherhood of the Door—but he’ll never reach it.”
“He said that within a few hours Ruth would go with the others through the Door!” cried Ennis, clinging beside him. “Campbell, we mustn’t let them get away now!”
Pursuers and pursued flashed on down the dark, broadening river, through mazes of shipping, the cutter hanging doggedly to the motor-boat’s trail. The lights of London had dropped behind and those of Tilbury now gleamed away on their left.
Bigger, stronger waves now tossed and pounded the cutter as it raced out of the river mouth toward the heaving black expanse of the sea. The Kent coast was a black blur on their right; the gray motor-boat followed it closely, grazing almost beneath the Sheerness lights.
“He’s heading to round North Foreland and follow the coast south to Ramsgate or Dover,” the cutter captain cried to Campbell. “But we’ll catch him before he passes Margate.”
The quarry was now but a quarter-mile ahead. Steadily as they roared onward the gap narrowed, until in the glare of the searchlight they could make out every detail of the powerful gray motor-boat plunging through the tossing black waves.
They saw Chandra Dass’ dark face turn and look back at them, and the cutter captain raised his speaking-trumpet to his lips and shouted over the roar of motors and dash of waves.
“Stand by or we’ll fire at you!”
“He won’t obey,” muttered Campbell between his teeth. “He knows we daren’t fire with the girl in the boat.”
“Yes, blast him!” exclaimed the captain. “But we’ll have him in a few minutes, anyway.”
The thundering chase had brought them into sight of the lights of Margate on the dark coast to their right. Now only a few hundred feet of black water separated them from the fleeing craft.
Ennis and the inspector, gripping the stanchions of the rushing cutter, saw a white figure suddenly stand erect in the boat ahead and wave its arms to them. The gray motor-boat slowed.
“It’s Chandra Dass, and he’s signaling that he’s giving up!” Ennis cried. “He’s stopping!”
“By heavens, he is!” Campbell said. “Drive alongside him, and we’ll soon have the irons on him.”
The cutter, its own motors hastily throttled down, shot through the water toward the slowing gray craft. Ennis saw Chandra Dass standing erect, awaiting their coming, he and the two Malays beside him holding their hands in the air. He saw a half-dozen or more white-wrapped forms in the bottom of the boat, lying motionless.
“There are their prisoners!” he cried. “Bring the boat closer so we can jump in!”
He and Campbell, their pistols out, hunched to jump as the cutter drove closer to the gray motor-boat. The sides of the two craft bumped, the motors of both idling noisily. Then before Ennis and Campbell could jump into the motor-boat, things happened with cinema-like rapidity. Two of the still white forms at the bottom of the motor-boat leaped up and like suddenly uncoiled springs shot through the air into the cutter. They were two other Malays, their dark faces flaming with fanatic light, keen daggers glinting in their upraised hands.
“’Ware a trick!” yelled Campbell. His gun barked, but the bullet missed and a dagger slit his sleeve.
The Malays, with wild, screeching yells, were laying about them with their daggers in the cutter, insanely.
“God in heaven, they’re running amok!” choked the cutter captain.
His slashed neck spurting blood and his face livid, he fell. One of his men slumped coughing beside him, another victim of the crazy daggers.
CHAPTER 3
Up the Water-Tunnel
The man at the searchlight sprang for the maddened Malays, tugging at his pistol as he jumped. Before he got the weapon out, a dagger slashed his jugular and he went down gurgling in death. One of the Malays meanwhile had knocked Inspector Campbell from his feet, his knife-hand swooping down, his eyes blazing.
Ennis’ gun roared and the bullet hit the Malay between the eyes. But as he slumped limply, the other fanatic was upon Ennis from the side. Before Ennis could whirl to meet him, the attacker’s knife grazed down past his cheek like a brand of living fire. He was borne backward by the rush, felt the hot breath of the crazed Malay in his face, the dagger-point at his throat.
Shots roared quickly, one after another, and with each shot the Malay pressing Ennis back jerked convulsively. With the light of murderous madness fading from his eyes, he still strove to drive the dagger home into the American’s throat. But a hand jerked him back and he lay prostrate and still.
Ennis scrambled up to find Inspector Campbell, pale and determined, over him. The detective had shot the attacker from behind.
The captain of the cutter and two of his men lay dead in the cockpit beside the two Malays. The remaining seaman, the helmsman, held his shoulder and groaned.
Ennis whirled. The motor-boat of Chandra Dass was no longer beside the cutter, and there was no sight of it anywhere on the black sea ahead. The Hindoo had taken advantage of the fight to make good his escape with his two other servants and their prisoners.
“Campbell, he’s gone!” cried the young American frantically. “He’s got away!”
The inspector’s eyes were bright with cold flame of anger. “Yes, Chandra Dass sacrificed these two Malays to hold us up long enough for him to escape.”
Campbell whirled to the helmsman. “You’re not badly hurt?”
“Only a scratch, but I nearly broke my shoulder when I fell,” answered the man.
“Then head on around North Foreland!” Campbell cried. “We may still be able to catch up to them.”
“But Captain Wilson and the others are killed,” protested the helmsman. “I’ve got to report—”
“You can report later,” rasped the inspector. “Do as I say—I’ll be responsible.”
“Very well, sir,” said the helmsman, and jumped back to the wheel.
In a minute the big cutter was roaring ahead over the heaving black waves, its searchlight clawing the darkness ahead. There was no sign now of the craft of Chandra Dass ahead. They raced abreast of the lights of Margate, started rounding the North Foreland, pounded by bigger seas.
Inspector Campbell had dragged the bodies of the dead policemen and their two slayers down into the cabin of the cutter. He came up and crouched down with Ennis beside Sturt, the helmsman.
“I found these on the two Malays,” Campbell shouted to the American, holding out two little objects in his spray-wet hand.
Each was a flat star of gray metal in which was set a large oval, cabochon-cut jewel. The jewels flashed and dazzled with deep color, but it was a color wholly unfamiliar and alien to their eyes.
“They’re not any color we know on earth,” Campbell shouted. “I believe these jewels came
