"Do you remember what became of the bottle of digitalin?" he asked, fumbling in the closet.

Mechanically I felt in my own pockets; it was not there. I shook my head.

"I don't seem to remember what became of it--perhaps we left it there.

In fact, we must have left it there."

"I don't like to have such things lying around loose," remarked Kennedy, taking up his hat and coat with forced energy. "I think we had better get it."

Elaine had spent rather a sleepless night after the attempt to poison her which had miscarried and resulted in poisoning Kennedy.

To keep her mind off the thing, she had already started to take down the decorations. Jennings and Marie, as well as a couple of workmen, were restoring the library to its normal condition under the direction of Aunt Josephine.

The telephone rang and Elaine answered it. Her face showed that something startling had happened.

"It was Jameson," she cried, almost dropping the receiver, overcome.

They all hurried to her. "He says that Mr. Kennedy and he were visiting that Chinaman this morning and Mr. Kennedy suffered a relapse--is dying there, in the Chinaman's apartment. He wants us to come quickly and bring that medicine that they used last night. He says it is on the tabaret in the library. Marie, will you look for it? And, Jennings, get the car right away."

Jennings hurried from the room, and a moment later Marie had found the bottle behind some ornaments on the tabaret and came back with it.

Scarcely knowing what to do, Elaine, followed by Aunt Josephine, had rushed from the house, hatless and coatless, just as the car swung around from the garage in the rear. Jennings went out with the wraps.

They seized them and leaped into the car, which started off swiftly.

It was only a matter of minutes when they pulled up before the apartment house where Wu had taken the suite from which Long Sin had telephoned the message in my name. Together Elaine and Aunt Josephine hurried in.

Kennedy went directly from the laboratory to the Dodge house.

I don't think I ever saw such an expression of surprise on anybody's face as that on Jennings's when he opened the door and saw us. He was aghast. Back of him we could see Marie. She looked as if she had seen a ghost.

"Is Miss Elaine in?" asked Kennedy.

Jennings was even too dumfounded to speak.

"Why, what's the matter?" demanded Kennedy.

"Then--er--you are not ill again?" he managed to blurt out.

"Ill again?" repeated Kennedy.

"Why," explained Jennings, "didn't Mr. Jameson just now telephone that you had had a relapse in the apartment of that Chinaman, and for Miss Elaine to hurry over there right away with that bottle of medicine?"

Kennedy waited to hear no more. Seizing me by the arm, he turned and dashed down the steps and back again into the taxicab in which we had come.

In Wu's apartment Long Sin was giving his secretary and another Chinaman the most explicit instructions. As he finished each nodded and showed him a Chinese dirk concealed under his blouse.

Just then a knock sounded at the door. The secretary opened it, and Aunt Josephine and Elaine almost ran in. Before they knew it, the secretary had locked the door.

Long Sin rose and bowed with a smile.

"Where is Mr. Kennedy?" demanded Elaine. Long Sin bowed again, spreading out his hands, palm outward.

"Mr. Kennedy? He is not here."

Then, straightening up, he faced the two women squarely.

"You have a ring that means much to me," he said quickly. "The only way to get it from you was to bring you here."

He was pointing now at the ring on Elaine's finger. She looked at it a moment in surprise, then at the menacing Chinaman, and turned quickly.

She ran to the door. It was locked.

Long Sin, motionless, smiled. "There is no way to get out," he murmured.

Aunt Josephine was standing now with her back to the door leading into another room. She happened to look up and saw the secretary, who was near her and half turned away. From where she was standing she could see the murderous dirk up his sleeve.

She acted instantly. Without a word she summoned all her strength and struck him. The secretary stumbled.

"Elaine," she cried, "look out! they have knives."

Before Elaine knew it Aunt Josephine had taken her by the arm, had pulled her into the back room, and, although Long Sin and the others had rushed forward, managed to slam the door and lock it.

The Chinamen set to work immediately to pry it open.

While they were at work on the doer, which was already swaying, Aunt Josephine and Elaine were running about, trying to find an outlet from the room.

There seemed to be no way out. Even the windows were locked.

"I don't know why they want the ring," whispered Aunt Josephine, "but they won't get it. Give it to me, Elaine."

She almost seized the ring, hiding it in her waist. As she did so the door burst open and Wu, Long Sin and the other Chinamen rushed in.

A second later they seized Elaine and Aunt Josephine.

Kennedy and I dashed up before the apartment house in which we knew that Long Sin lived, leaped out of the car and hurried in.

It was on the second floor, and we did not wait for the elevator but took the steps two at a time. Kennedy found the door locked. Instantly he whipped out his revolver and shot the lock in pieces. We threw ourselves against the door, the broken lock gave way and we rushed in through the front room.

No one was there, but in a back room we could hear sounds. It was Elaine and Aunt Josephine struggling with the Chinamen. Long Sin and the others had seized Elaine and Aunt Josephine was trying to help her just as we rushed in. With a blow Kennedy knocked out the secretary, while I struggled with the other Chinamen who blocked the way.

Then Kennedy went directly at Long Sin. They struggled furiously.

Long Sin, with his wonderful knowledge of jiu-jitsu, might not have been a match for six other Chinamen, but he was for one white man. With a mighty effort he threw Kennedy, rushed for the door and, as he pa.s.sed through the outside room, seized a Tong axe from the wall.

Afraid of the wonderful jiu-jitsu, I had picked up the first thing handy, which was a tabaret. I literally broke it over the head of my Chinaman, then turned and dashed out after Long Sin just as Kennedy picked himself up and followed.
