A telephone call put Ham in touch with the elderly lawyer who served Scott S. Osborn and his brother. Ham explained what he desired.
"The family might hesitate about complying with the wishes of a stranger," he finished. "It would help greatly if you would sort of put the O.K. on me. I am, of course, working for the interest of your clients."
"I'll do better than that!" declared the other attorney. "I shall be at the home of Osborn's brother when you arrive. When I advise them of the situation, I am sure they will do as you desire."
"That will be great," Ham assured him.
Ham hurried to his bachelor quarters, in a club which was one of the most luxurious in the city, although not widely known. The members were all wealthy men who wished to live quietly.
A change of clothing was the object of Ham's visit. He donned formal evening garb, secured a more natty-looking sword cane from a collection he kept on hand, and took a taxi to the home of Scott S. Osborn's brother.
The dwelling was large. It might have been mistaken for a small apartment building.
Dismissing his taxi, Ham mounted the steps. He was about to ring the bell when his hand froze.
A stream of scarlet was crawling slowly from under the door.
Ham listened. He could hear nothing. He tried the knob. It turned, but the door, after opening about two inches, would go no farther. Ham shoved. He could tell that he was pushing against a body lying on the floor inside.
He got the panel half open, put his head in cautiously. The vestibule was brilliantly lighted. No living person was in sight.
The body of the old lawyer whom Ham had called not many minutes ago, had been blocking the door. The elderly man had been stabbed at least fifteen times.
Ham, his sword cane ready, stepped inside. The weight of the dead man against the door shoved it shut. The lock clicked loudly.
As though that were a signal, a man hurtled from a near-by door.
The fellow was chunky, lemon-complected, sloping of eye. His face was a killer mask. He waved a sword.
It was Liang-Sun, although Ham didn't know that, not having seen him before.
Liang-Sun got a shock when Ham unsheathed the slender, rippling steel blade of his sword cane. Ham's blade leaped out hungrily.
With desperate haste, Liang-Sun parried. He was surprised, but still confident. Among the fighting men of Mongolia and China, he had been considered quite a swordsman.
Ten seconds later, Liang-Sun's confidence leaked out like water from a gunnysack. The air before his face had apparently turned into a whistling hell of sharp steel. A chunk of his hat brim was sliced off and fluttered away.
Liang-Sun felt like a man clubbing a swarm of hornets with a stick. Backing up, he sought to haul a revolver from his coat pocket with his left hand. He hadn't wanted to use the gun before, because of the noise. But he would be glad to do so now.
A dazzling slash of Ham's sword cut the whole skirt and pocket from Liang-Sun's coat, and the revolver bounced away.
STEEL whined, clashed, rasped. Both fighters sought to get to the revolver. Neither could quite do it.
Liang-Sun felt a tickling sensation across his stomach. He looked down and saw his clothing had been slit wide. Another inch would have finished him.
He backed away swiftly, passing through the door from which he had leaped. Ham followed, cutting and parrying briskly.
A man was sprawled across a table in the room. He had white hair, ruddy features. He, too, had been stabbed to death.
Ham had seen the man once before, perhaps a year ago. It was the brother of Scott S. Osborn.
A wall safe gaped open.
On the table with the dead man lay a heap of jewels, rings, currency.
This explained the situation to Ham.
The Mongol messenger had come to demand ransom, had seen the money, and decided a bird in hand was better than one in the bush. He had slain and robbed Osborn's brother, rather than bother with ransom.
The poor old lawyer out by the door had been murdered when he arrived.
White with rage, Ham redoubled his sword play. Liang-Sun fairly ran backward. A sudden spring put him through a door. He slammed it. Ham pitched against the panel. It resisted.
Seizing a chair, Ham battered the door down. He ran across a dining room, then a kitchen. A rear door gaped open beyond. It let him into an alleylike court. There was only one exit from this, a yawning space between two buildings, to the right.
An indistinct, rapidly moving figure dived into this opening.
Ham pursued. He pitched headlong between the buildings, came out on the walk, and saw his quarry scuttle under a street lamp at the corner.
Ham set out after him-only to bring up sharp as a powerful voice came to him from a near-by door recess.
"I'll follow him, Ham!" the voice said.
It was Doc Savage.
Ham understood, then, why Doc had directed, in the message on the skyscraper window, that the ransom-demanding courier was not to be followed. Doc intended to do the trailing, hoping to be led to the master mind who was behind all this callous, inhuman bloodletting.
In order not to make the fleeing Oriental suspicious, Ham continued his chase. But at the first corner, he deliberately took the wrong turn.
When he came back, there was no sign of Doc or the half-caste Mongol.

THE STOLEN GLASS
AT the precise moment Ham was wondering about them, Doc and Liang-Sun were five blocks distant. Liang-Sun was just climbing the steps of a Third Avenue elevated station.
The Mongol had lived much of his life in violence, and knew enough to watch his back trail. He saw nothing suspicious. He kept wary eyes on the stairway until a train came
in. Even after he boarded the almost deserted train, he watched the platform he had just quitted, as well as the one on the other side of the tracks. He saw no one — not a single other passenger got aboard.
He should have watched the rear platform. Doc was already ensconced there. He had climbed a pillar of the elevated a short distance above the station and run down the tracks.
The train clanked away southward, disgorging a few passengers at each stop.
At Chatham Square, very close to Chinatown, Liang-Sun alighted. To make sure no one got off the train after him who seemed in the least suspicious, he waited on the platform until the cars pulled out. Greatly relieved, he finally descended.
Doc Savage, having slid down a pillar of the elevated, was waiting for him, seated in some one's parked car.
Liang-Sun walked rapidly toward the Oriental section. He passed two sidewalk peddlers who, even at this late hour, were offering for sale filthy trays of melon seeds and other celestial dainties.
A moment later, Doc Savage also sauntered past the peddlers.
Both venders of melon seeds and dainties shoved their trays of merchandise in the handiest waste can and followed Doc. Their hands, folded across their stomachs, fingered large knives in their sleeves. Their faces, the color of old straw, were determined.
Doc did not look back. Several times, he glanced down at his hands swinging at his sides. In the palm of each hand was a small mirror.
The mirror showed him the two who haunted his trail.
Doc's bronze features held no feeling as he watched. This master of the Mongols was clever in having men follow Liang-Sun to see that no one dogged his tracks.
Gone were any hopes Doc had of locating the master mind through Liang-Sun — unless he could be induced to talk by force.
Doc's left hand wandered casually into his pocket, drew out four of the glass balls filled with anaesthetic. Holding his breath, Doc dropped them. They shattered, releasing the colorless, odorless vapor.
