“Ah, good morning, doctor,” he said, coming forward. “I’m afraid I didn’t thank you for the assistance you gave me with the young lady the other night. Permit me to make amends.”

“No thanks needed,” Doremus assured him. “How’s the patient getting on?”

“The wound’s filling in nicely. No sepsis. I’m going up now to have a look at her.” He turned inquiringly to the District Attorney. “No objection, I suppose.”

“None whatever, doctor,” said Markham. Then he rose quickly. “We’ll come along, if you don’t mind. There are a few questions I’d like to ask Miss Ada, and it might be as well to do it while you’re present.”

Von Blon gave his consent without hesitation.

“Well, I’ll be on my way—work to do,” announced Doremus breezily. He lingered long enough, however, to shake hands with all of us; and then the front door closed on him.

“We’d better ascertain if Miss Ada has been told of her brother’s death,” suggested Vance, as we went up the stairs. “If not, I think that task logically devolves on you, doctor.”

The nurse, whom Sproot had no doubt apprised of Von Blon’s arrival, met us in the upper hall and informed us that, as far as she knew, Ada was still ignorant of Chester’s murder.

We found the girl sitting up in bed, a magazine lying across her knees. Her face was still pale, but a youthful vitality shone from her eyes, which attested to the fact that she was much stronger. She seemed alarmed at our sudden appearance, but the sight of the doctor tended to reassure her.

“How do you feel this morning, Ada?” he asked with professional geniality. “You remember these gentlemen, don’t you?”
