"There's some mistake, isn't there? You don't want me—this morning?"

Diana regarded her composedly.

"Certainly I want you—to rehearse for to-night."

"To rehearse? Rehearse?" Olga's voice rose in a sharp crescendo of amazement. "Surely"—bending forward to peer into Diana's face—"surely you are not going to keep Max waiting while you—rehearse?"

"It's impossible for us to meet to-day," replied Diana steadily. "I had—forgotten—the Duchess's reception."

Olga made a gesture of impatience.

"But you must meet to-day," she said imperiously. "You must!
To-morrow it will be too late."

"Too late? How too late?"

Miss Lermontof hesitated a moment. Then she said quietly:—

"I happen to know that Max is leaving England to-night."
