Just then another cab stopped up the street, and as we turned to leave the vestibule Kennedy drew back. It was too late, however, not to be seen. A man had just alighted and, in turn, had started back, also realizing that it was too late. It was Chapelle! There was nothing to do but to make the best of it.

"Shadowing the shadowers?" queried Kennedy, keenly watching the play of his features under the arc-light of the street.

"Miss Cynthia asked me to follow her mother the other night," he answered, quite frankly. "And I have been doing so ever since."

It was a glib answer, at any rate, I thought.

"Then, perhaps you know something of Reba Rinehart, too," bluffed Kennedy.

Chapelle eyed us a moment, in doubt how much we knew. Kennedy played a pair of deuces as if they had been four aces instead.

"Not much," replied Chapelle, dubiously. "I know that Mrs. Blakeley has been paying money to the old woman, who seems to be ill. Once I managed to get in to see her. It's a bad case of pernicious anemia, I should say. A neighbor told me she had been to the college hospital, had been one of Doctor Haynes's cases, but that he had turned her over to his son. I've seen Hampton Haynes here, too."

There was an air of sincerity about Chapelle's words. But, then, I reflected that there had also been a similar ring to what we had heard Hampton say. Were they playing a game against each other? Perhaps--but what was the game? What did it all mean and why should Mrs. Blakeley pay money to an old woman, a charity patient?

There was no solution. Both Kennedy and Chapelle, by a sort of tacit consent, dismissed their cabs, and we strolled on over toward Broadway, watching one another, furtively. We parted finally, and Craig and I went up to our apartment, where he sat for hours in a brown study.

There was plenty to think about even so far in the affair. He may have sat up all night. At any rate, he roused me early in the morning.

"Come over to the laboratory," he said. "I want to take that X-ray machine up there again to Blakeley's. Confound it! I hope it's not too late."

I lost no time in joining him and we were at the house long before any reasonable hour for visitors.

Kennedy asked for Mrs. Blakeley and hurriedly set up the X-ray apparatus. "I wish you would place that face mask which she was wearing exactly as it was before she became ill," he asked.

Her mother did as Kennedy directed, replacing the rubber mask as Virginia had worn it.

"I want you to preserve that mask," directed Kennedy, as he finished taking his pictures. "Say nothing about it to any one. In fact, I should advise putting it in your family safe for the present."

Hastily we drove back to the laboratory and Kennedy set to work again developing the second set of skiagraphs. I had not long to wait, this time, for him to study them. His first glance brought me over to him as he exclaimed loudly.

At the point just opposite the sore which he had observed on Virginia's forehead, and overlying the sella turcica, there was a peculiar spot on the radiograph.

"Something in that mask has affected the photographic plate," he explained, his face now animated.

Before I could ask him what it was he had opened a cabinet where he kept many new things which he studied in his leisure moments. From it I saw him take several gla.s.s ampules which he glanced at hastily and shoved into his pocket as we heard a footstep out in the hall. It was Chapelle, very much worried. Could it be that he knew his society clientele was at stake, I wondered. Or was it more than that?

"She's dead!" he cried. "The old lady died last night!"

Without a word Kennedy hustled us out of the laboratory, stuffing the X-ray pictures into his pocket, also, as we went.

As we hurried down-town Chapelle told us how he had tried to keep a watch by bribing one of the neighbors, who had just informed him of the tragedy.

"It was her heart," said one of the neighbors, as we entered the poor apartment. "The doctor said so."

"Anemia," insisted Chapelle, looking carefully at the body.

Kennedy bent over, also, and examined the poor, worn frame. As he did so he caught sight of a heavy linen envelope tucked under her pillow.

He pulled it out gently and opened it. Inside were several time-worn doc.u.ments and letters. He glanced over them hastily, unfolding first a letter.

"Walter," he whispered, furtively, looking at the neighbors in the room and making sure that none of them had seen the envelope already. "Read these. That's her story."

One glance was sufficient. The first was a letter from old Stuart Blakeley. Reba Rinehart had been secretly married to him--and never divorced. One paper after another unfolded her story.

I thought quickly. Then she had had a right in the Blakeley millions.

More than that, the Blakeleys themselves had none, at least only what came to them by Blakeley's will.

I read on, to see what, if any, contest she had intended to make. And as I read I could picture old Stuart Blakeley to myself--strong, direct, unscrupulous, a man who knew what he wanted and got it, dominant, close-mouthed, mysterious. He had understood and estimated the future of New York. On that he had founded his fortune.

According to the old lady's story, the marriage was a complete secret.

She had demanded marriage when he had demanded her. He had pointed out the difficulties. The original property had come to him and would remain in his hands only on condition that he married one of his own faith. She was not of the faith and declined to become so. There had been other family reasons, also. They had been married, with the idea of keeping it secret until he could arrange his affairs so that he could safely acknowledge her.

It was, according to her story, a ruse. When she demanded recognition he replied that the marriage was invalid, that the minister had been unfrocked before the ceremony. She was not in law his wife and had no claim, he a.s.serted. But he agreed to compromise, in spite of it all. If she would go West and not return or intrude, he would make a cash settlement. Disillusioned, she took the offer and went to California.

Somehow, he understood that she was dead. Years later he married again.

Meanwhile she had invested her settlement, had prospered, had even married herself, thinking the first marriage void. Then her second husband died and evil times came. Blakeley was dead, but she came East.

Since then she had been fighting to establish the validity of the first marriage and hence her claim to dower rights. It was a moving story.

As we finished reading, Kennedy gathered the papers together and took charge of them. Taking Chapelle, who by this time was in a high state of excitement over both the death and the discovery, Kennedy hurried to the Blakeley mansion, stopping only long enough to telephone to Doctor Haynes and his son.

Evidently the news had spread. Cynthia Blakeley met us in the hall, half frightened, yet much relieved.

"Oh, Professor Kennedy," she cried, "I don't know what it is, but mother seems so different. What is it all about?"

As Kennedy said nothing, she turned to Chapelle, whom I was watching narrowly. "What is it, Carl?" she whispered.

"I--I can't tell," he whispered back, guardedly. Then, with an anxious glance at the rest of us, "Is your sister any better?"

Cynthia's face clouded. Relieved though she was about her mother, there was still that horror for Virginia.

"Come," I interrupted, not wishing to let Chapelle get out of my sight, yet wishing to follow Kennedy, who had dashed up-stairs.

I found Craig already at the bedside of Virginia. He had broken one of the ampules and was injecting some of the extract in it into the sleeping girl's arm. Mrs. Blakeley bent over eagerly as he did so. Even in her manner she was changed. There was anxiety for Virginia yet, but one could feel that a great weight seemed to be lifted from her.

So engrossed was I in watching Kennedy that I did not hear Doctor Haynes and Hampton enter. Chapelle heard, however, and turned.

For a moment he gazed at Hampton. Then with a slight curl of the lip he said, in a low tone, "Is it strictly ethical to treat a patient for disease of the heart when she is suffering from anemia--if you have an interest in the life and death of the patient?"

I watched Hampton's face closely. There was indignation in every line of it. But before he could reply Doctor Haynes stepped forward.

"My son was right in the diagnosis," he almost shouted, shaking a menacing finger at Chapelle. "To come to the point, sir, explain that mark on Miss Virginia's forehead!"

"Yes," demanded Hampton, also taking a step toward the beauty doctor, "explain it--if you dare."

Cynthia suppressed a little cry of fear. For a moment I thought that the two young men would forget everything in the heat of their feelings.

"Just a second," interposed Kennedy, quickly stepping between them.

"Let me do the talking." There was something commanding about his tone as he looked from one to the other of us.

"The trouble with Miss Virginia," he added, deliberately, "seems to lie in one of what the scientists have lately designated the 'endocrine glands'--in this case the pituitary. My X-ray pictures show that conclusively.
