"I wouldn't like to say," he returned, dodging, though we were all thinking of Dr. Loeb.

"But the motive?" demanded Craig. "What motive would there be?"

"Darius Moreton is very intimate with a certain person," he returned enigmatically. "It is even reported in town that he has left that person a large sum of money in his will in payment for his services, if you call them so, to the family."

He had evidently not intended to say so much and, although Craig tried in every way, he could not get the doctor to amplify what he had hinted at.

We returned to the Moreton house, Kennedy apparently much impressed by what Dr. Goode had said.

"If you will permit me," he asked, "I should like to have a few drops of blood from each of you."

"Goode tried that," remarked old Mr. Moreton. "I don't know that anything came of it. Still, I am not going to refuse, if Myra and Lionel agree."

Craig had already taken from his pocket a small case containing a hypodermic and some little glass tubes. There seemed to be no valid objection and from each of them he drew off a small quantity of blood. As he worked, I thought I saw what he had in mind. Could there be, I wondered, an X-ray outfit or perhaps radium concealed about the living rooms of the house? First of all, it was necessary to verify Dr. Goode's observations.

We chatted a few moments, then took leave of Myra Moreton.

"Keep up your courage," whispered Craig with a look that told her that he had seen the conflict between loyalty to her father and to her lover.
