Doc noted his indecision. "Call your owners. Ask them about it."

The Malay Queen commander hurriedly complied. He secured a radio-land-line connection with the headquarters of his company in San Francisco He gave a brief description of the situation.

"What about this man Savage?" he finished.

He was wearing earphones. The others did not hear what he was told.

But Captain Hickman turned about as pale as his ruddy face permitted. His hands shook as he placed the headset on the table. He stared at Doc as if wondering what manner of man the big bronze fellow was.

"I have been ordered to do anything you wish, even to turning my command over to you," he said briskly.

First Mate Jong stared as if this was hard to believe. Then he made a gesture of agreement. "I will start an immediate search of the ship. And I can promise you it will be done so smoothly no one will as much as know it is going on."

He hurried out.

Doc and Renny returned to the royal suite.

Renny eyed Doc curiously. "Just what kind of a pull have you got with the company that owns this boat, anyhow?"

"Some months ago the concern got pinched for money," Doc said slowly, reluctantly. "Had it ceased operating, several thousand men would have been out of jobs. A loan of mine tided them over."

RENNY sank heavily into a chair. At times he felt a positive awe of the mighty bronze man. This was one of the occasions.

It was not the fact that Doc was wealthy enough to take an important hand in a commercial project such as this, that took Renny's breath. It was the uncanny way such things as this turned up — the way the bronze man seemed to have a finger in affairs in every part of the world.

Renny knew Doc Possessed fabulous wealth, a golden treasure.trove alongside which the proverbial ransom of a king paled into insignificance. Doc had a fortune great enough to buy and sell some nations.

Renny had seen that treasure. The sight of it had left him dazed for weeks. It lay in the lost Valley of the Vanished, a chasm in the impenetrable mountains of the Central American republic of Hidalgo. This strange place was peopled by a golden-skinned folk, pure-blooded descendants of the ancient Mayan race. They guarded the wealth. And they sent burro trains of it to the outside world as Doc needed it.

There was one string attached to the wealth — Doc was to use it only in projects which would benefit humanity. The Mayans had insisted Upon that. It was to he used for the cause of right.

Their insistence was hardly needed, for it would not have received any other disposition at Doc's hands. Doc's life was dedicated to that same creed — to go here and there, from one end of the world to the other, striving to help those who needed help, punishing those who were malefactors.

This was the one thing that motivated Doc's every act.

The same creed bound his five men to Doc. That, and their love of adventure, which was never satisfied.

THE search for Monk, Long Tom, and Johnny drew a blank.

"I can assure you we searched every stateroom aboard, and every box and bale of the cargo!" declared slant-eyed First Mate Jong. "There was no sign of three prisoners."

"I don't believe they're aboard!" Captain Hickman Captain Hickman had taken to speaking in a low voice when in the presence of the big bronze man. He was completely in awe of Doc, and his manner showed it.

"I'm still betting they're aboard!" Renny grunted. "Unless — " He wet his lips. His enormous fists became flinty blocks. It had just occurred to him that Tom Too might have become alarmed and slain the three captives, shoving their bodies overboard.

Renny's fears were dispelled by a plain white card they found under the door of the royal suite the next day. It said:

The straw did not break the back of the

camel, you may be glad to ]earn. But

it came very near.

TOM TOO.

"That snake is getting cocky!" Renny gritted. "How could the search have missed our three pals, granting they're aboard?"

"No telling how many of the crew have been bribed," Doc pointed out.

THE Malay Queen stopped at Honolulu for a few hours. Doc had gotten instructions to the flashy cockney and the disheveled tropical tramp, otherwise Ham and Mindoro, and they all kept close watch on such persons as went ashore.

No sign of Long Tom, Monk, or Johnny was discovered in the close inspection.

Immediately after the Malay Queen put to sea again, Doc Savage instituted a single-handed search for his three captive friends. Due to the great size of the liner, the task was a nearly impossible one.

A hundred of Tom Too's corsairs could conceivably have been aboard without Doc being able to identify one of them. Every Mongol, Jap, Chinaman and half-caste was a potential suspect.

Doc began in the hold. He opened barrels, boxes, and bales of cargo. He examined the fresh-water tanks. The Malay Queen was an oil burner, and he scrutinized the fuel tanks. Then he began on the D deck cabins and worked up.

It was on D deck, well toward the stern, that his hunt produced first results.

He found a stateroom which had been used, but which was now unoccupied.

The mirror was missing.

On the floor was a small smudge. Analyzing this, Doc learned it was the crayon he used for his invisible writing.

These discoveries told him a story. The prisoners were actually aboard. They had been kept here for a time. Monk had been caught trying to leave a secret message on the mirror. The mirror had been removed and thrown overboard. Either Monk or his captors had destroyed the crayon by stamping upon it. Probably that was Monk's work, since Tom Too's men would have wanted the crayon to learn its composition.

Doc continued his prowling. It was an interminable task. The Malay Queen had more than four hundred cabins. While Doc searched, Tom Too could easily move the prisoners to a stateroom Doc had already scrutinized.

DOC did not finish the hunting. Tom Too struck at their lives the second night out of Honolulu.

Doc and Renny had been ordering meals sent to their suite to keep Tom Too from getting the idea they were subsisting off rations carried in their baggage. The meals which were brought in to them they chucked overboard. This task usually fell to Renny, while Doc watched for enemies.

Gulls were following the Malay Queen. Swooping, the birds snatched anything edible which was tossed overside before the articles reached the water.

The birds bolted portions of the food Renny heaved over the rail.

Two of the feathered scavengers did not fly fifty yards before their wings collapsed and they plummeted into the sea, lifeless.

"Poison!" Renny grunted.

The cook and steward who had come in contact with the meal put in an uncomfortable half hour in front of Doc's probing golden eyes. They convinced the bronze giant they knew nothing of the poison.

Captain Hickman was perturbed when he heard of the attempt. He acted as scared as though his own life had beer attempted.

First Mate Jong was also solicitous. "Do you wish me to make a second search of the ship?"

"It would be useless," Doc replied.

Jong stiffened perceptibly. "I hope, sir, you do not distrust the personnel of this craft!"

"Not necessarily."

Doc and Renny redoubled their caution.

The next night they found poisoned needles concealed in their pillows.

A few minutes later, when Doc turned on the water in the bathroom, a villainous, many-legged creature hurtled out of the hot-water faucet.

At this Renny's hair stood on end. He was in the habit of carelessly thrusting his big hands under the faucet when he washed.
