Five words went back into the microphone before the receiver went dead.

"I'm coming, Crane! Hold on!"

Friday had seen the Hawk in such moments before, and he knew the sight; but the navigator, Harkness, had not been with Carse very long, and now he stood silent, motionless, while despite himself a shiver ran down his spine as he stared at the tight-pressed bloodless lips and the gray eyes, cold now as space. He started nervously when the Hawk turned and looked him in the eye.

"I want speed," came his quiet, soft, deceptive voice. "I want that hour's running time sliced by a third. Streak through that atmosphere."

"Yes, suh!" answered Friday.

"And you"—to Harkness—"be very sure you get out every ounce she's got. Tell the engineer personally."

"Full speed. Yes, sir," said the navigator, and felt relieved when Carse turned his eyes away. For the Hawk, as always when he learned that property had been ravaged and his friends shot down, seemed less human than the Indrots at the far end of the frigid deeps of space he roamed. His face was mask-like, graven, totally expressionless: blood had been shed, and for each ounce another had to be spilled to balance the scales. At a speaking tube that reached aft to the three other members of the crew, he whispered: "Fighting posts. Arm and be ready for action. Pirates are attacking ranch," and then went noiselessly to the forward electelscope. Meanwhile Friday kept his eyes strictly on the dials before him and held the space-stick rigid, while aft, in the ship's other compartments, three men strapped on ray-gun belts and wondered who was doomed to be caught in the swoop of the Hawk.

arse himself wondered that. The raider so far showed as a newcomer to the frontiers of space; he was one who as yet had never faced the Hawk, one to whom the tales that were told of him seemed laughable, to whom the rich consignment of horn looked like a gift. Certainly such an open attack did not resemble Ku Sui's subtle methods, or those of his several henchmen, pirates of space all; they, rather, struck behind his back, and then only when the infamous Eurasian had prepared what seemed an escape-proof trap.

"Foolish to raid when I'm so close!" he murmured as he trained the electelscope and peered into its eye-piece. "Stupid! Unless ..."

Friday, at the space-stick, mopped the trickles of sweat from his brow and with a vast sigh shifted his bulk. The job of speeding into an atmospheric pressure was always ticklish, and it was with some relief that he reported "Into th' atmosphere, suh," according to routine. He waited for the usual acknowledgment, and when it did not come repeated his observation in a louder voice. Two full minutes of silence passed. Then, finally, Hawk Carse turned from the electelscope, and even the negro shivered at sight of the deadly mask that was his face.

For the ranch-house in its clearing had dimly appeared in the electelscope just as Friday had spoken.

Carse spoke.

"More speed, if it burns us up," came his almost whispered words. "I want much more speed."

Harkness gulped. "Yes, sir," he said, and, moistening his lips, he returned to the engine-room. The frigid gray eyes swung back to the sight that was revealed on Iapetus.

The long, lean shape of a rakish space ship was resting on the soil some three hundred yards from the ranch-house, and between were the hazy figures of six men, busily dragging as many boxes towards their craft. The boxes contained the whole half-year's harvest of phanti horns, and had obviously been looted from the house. The resistance had been overcome; the pirate raid had succeeded. The trim, gray-painted ranch-house was lifeless....

he Hawk switched off the electelscope. His colorless lips were compressed very tightly. "I'll take the helm," he said curtly to Friday. "Turn on the defensive web, and prepare all ray batteries."

"Yes, suh!" The negro's big, yellow-palmed hands worked dexterously among the instruments to his right; then, amidships, grew a shrill whine which keened upward in pitch. A few sparks raced by the Star Devil's after ports, quickly to disappear after they left the almost invisible envelope of delicate bluish light that entirely wrapped her hull.

She was making dangerous speed. The wind screamed as she streaked through the satellite's atmosphere, and the great friction of her passage raised her outer shell to a perilous glow. The altitude dial's finger almost jumped from forty thousand to thirty-five.

"Ready for bow-ray salvo."

"Aye, sir!" replied Harkness, and a moment later repeated crisply: "All ready for bow-ray salvo, sir!" His voice showed no sign of the fear within him—fear that the Star Devil's outer hull would reach the melting point—but his lips fell apart and his face lost its discipline when the Hawk next spoke and acted.

"Steady," came the low whisper to his ears—and he saw the controlling space-stick being shoved down as far as it would go.

CHAPTER II

Pursuit

hat was the Hawk's method, and it had given him the name which he had made famous. It was characteristic of the man that he preferred to strike at an enemy ship in a wild, breath-taking swoop, even as the fierce hawk plummets from high heaven to sink its talons deep into the flesh of its more sluggish prey. Nerves were uncomfortable things to have on such occasions, and Harkness had them, and accordingly he felt his heart hammer and something tight seemed to bind his throat. He tried to assume the unshakable calmness of the motionless figure at the stick, but could not, for his body was only flesh and blood—and Hawk Carse was tempered, frosty, steel. Through staring eyes the navigator watched the surface of Iapetus rushing into the bow ports, watched it spread accelerating outward, until he could plainly see the pirate ship lying there, and the nearby figures of men tugging at the heavy boxes of horns.

His eyes were on those figures when they broke. First they teetered hesitantly a moment, glancing wildly around and up at the vision of death that was coming like a silver comet from the skies, and then they melted apart. Three scrambled towards the rim of jungle foliage close at hand, while their fellows leaped in the other direction, trying to make an open port in their craft. Harkness saw them tumble headlong through it and slam it shut. Then a web of blue streaks appeared around the ship, and softened until her hull was bathed is ghostly bluish light.

"Their defensive ray-web's on, sir!" he managed to gasp. Carse, though close, might not have heard, so intently was he watching. The altitude dial's pointer reached for one thousand and slid past. Harkness's face was pale and drawn; his tight-gripped fingers and clenched teeth showed that he expected to crash into the ground in a molten, shapeless tomb of steel. But Friday was grinning, his teeth a slash of white.

"Stand by bow projectors," sounded the Hawk's clipped voice. The negro extended his hands and rumbled:

"Ready, suh."

"Fire."

"Fire!" Friday roared.

His rich laugh rang out and he whirled the wheels over. With a hissing as of a hundred snakes, the rays struck.
