Mr. Keen nodded. "Exactly. Let us drop him for a moment. . . . Are you perfectly well, Miss Southerland?"

"Why, yes."

"I'm glad of it. You are a trifle pale; you seem to be a little languid. . . . When do you take your vacation?"

"You suggested May, I believe," she said wistfully.

The Tracer leaned back in his chair, joining the tips of his fingers reflectively.

"Miss Southerland," he said, "you have been with us a year. I thought it might interest you to know that I am exceedingly pleased with you."

She colored charmingly.

"But," he added, "I'm terribly afraid we're going to lose you."

"Why?" she asked, startled.

"However," he continued, ignoring her half-frightened question with a smile, "I am going to promote you—for faithful and efficient service."
