"Yes."

"God be praised!" Henry stepped back, his eyes snapping with delight. "Ah, we will win it yet, that Cross!" he exulted; then cautiously took from an inside pocket a folded sheet of letter paper and with care removed from between the pages a piece of paper. "When Miss Grey was occupied in her effort to revive Mr. Whitney I looked quickly about the studio," he explained. "This paper caught my eye—and I bring it to you, Herr Captain."

"Thanks," laconically, laying the paper down on the desk. "One moment before you go," and from a well-filled wallet he extracted a treasury bill whose denomination caused Henry's eyes to beam with pleasure.

"At service, Herr Captain," he said, saluting. "I will return and report later."

"Very well, Henry," and the chauffeur bowed himself out, but on the other side of the door he hesitated, fingering Miller's tip with satisfaction.

"He is liberal, that von Mueller," he muttered. "But it is just as well not to tell him that there were two sheets of finger prints," and he went whistling down the corridor.

Tiptoeing to his door, Miller listened for a second, then, convinced that the chauffeur had moved away, he turned the key in the lock. Going to his desk, he picked up the sheet of finger prints and studied them long and attentively; then glanced down at his right hand. Horror lurked in the depths of his frank eyes.

"The mark of Cain," he stammered, and opening the silver frame containing Kathleen Whitney's photograph, he deftly slipped the paper between the two pieces of cardboard.

It was getting toward dusk when Mrs. Whitney stole softly into Kathleen's bedroom and stood looking down at her as she lay, eyes closed, white face pillowed on one shapely arm, her breath hardly stirring the laces on her gown. Convinced that she was asleep, she moved cautiously away, hoping not to disturb her, but at that moment Kathleen opened her eyes and raised herself on her elbow.
