"I must go, Mr. Brewster; I have an appointment at the hospital."

The judge grasped his hand warmly.

"Thank you, doctor!" he exclaimed, "I don't know what I should have done without you."

"Thank you, sir!" chimed in the banker, "I am greatly indebted to you."

"Don't mention it," replied the psychologist almost ironically.

He went out and the banker impatiently took out his watch.

"It's getting late!" he exclaimed; "where is this girl. I have no faith in her promises!"

As he spoke the library door opened and Annie appeared.

CHAPTER XVIII.

As Annie entered the room and caught sight of Mr. Jeffries, she instinctively drew back. Just at that moment the banker was, perhaps, the one man in the world whom she was most anxious to avoid. Captain Clinton no longer had any terror for her. Now that the missing witness had been found and the precious "suicide letter" was as good as in their possession there was nothing more to fear. It was only a question of time when Howard would be set free. But it was not in this girl's nature to be concerned only with herself. If she possessed a single womanly virtue, it was supreme unselfishness. There was some one beside herself to take into consideration--a poor, vacillating, weak, miserable woman who wished to do what was right and had agreed to do so, but who, in the privacy of her own apartments, had gone down on her knees and begged Annie to protect her from the consequences of her own folly. Her husband must not know. Annie had promised that if there was any way possible the knowledge of that clandestine midnight visit to Underwood's rooms should be kept from him. Yet there stood the banker! She was afraid that if they began questioning her in his presence she might be betrayed into saying something that would instantly arouse his suspicions.

Judge Brewster went quickly forward as she came in and led her to a chair. Captain Clinton and Mr. Jeffries eyed her in stolid silence.

Looking around in a nervous kind of way, Annie said quietly to the judge:

"May I speak to you alone, judge?"

"Certainly," replied the lawyer.

He was about to draw her aside when Captain Clinton interfered.

"One moment!" he said gruffly, "if this is all open and above board, as you say it is, judge--I'd like to ask the young lady a few questions."

"Certainly, by all means," said the judge quickly.

The captain turned and confronted Annie. Addressing her in his customary aggressive manner, he said:

"You promised Judge Brewster that you'd produce the woman who called at Underwood's apartment the night of the shooting?" Annie made no reply, but looked at the lawyer. The captain grinned as he added: "The witness wants instructions, judge."

"You can be perfectly frank, Mrs. Jeffries," said the lawyer rea.s.suringly. "We have no desire to conceal anything from Captain Clinton."

Annie bowed.

"Yes," she said slowly; "I promised Judge Brewster that she would come here to-night."

"Did she promise you to come?" growled the captain.

"Yes."

"Well, where is she?" he demanded.

"She hasn't come yet," she replied, "but she will, I'm sure--I know she will."

"How did you come to find her?" demanded the captain suspiciously.

Annie hesitated a moment and glanced at Mr. Jeffries. Then she said hesitatingly:

"That I--I cannot say--now."

Captain Clinton's ma.s.sive bulldog jaw closed with an ominous click.

"Decline to answer, eh? What's her name?"

She remained silent.

"What's her name?" he repeated impatiently.

"I cannot tell you," she said firmly.

"Do you know it?" he bellowed.

"Yes," she answered quietly.

"Know it, but can't say, eh? Hum!"

He folded his arms and glared at her. Mr. Jeffries now interfered.

Addressing Annie angrily, he said:

"But you must speak! Do you realize that my son's life is at stake?"

"Yes, I do," she replied quickly. "I'm glad to see that you are beginning to realize it, too. But I can't tell you yet----"

The judge turned to the police captain.

"I may tell you, captain, that even I myself have not succeeded in learning the name of this mysterious personage." Addressing Annie, he said: "I think you had better tell us. I see no advantage in concealing it any further."

Annie shook her head.

"Not yet," she murmured; "she will tell you herself when she comes."

"Ha! I thought as much!" exclaimed the banker incredulously.

The captain rose and drew himself up to his full height, a favorite trick of his when about to a.s.sert his authority.

"Well, when she does come!" he exclaimed, "I think you may as well understand she will be taken to headquarters and held as a witness."
