In truth, Why Not Pape’s “professional” instinct had not been very communicative. But the result of his unprofessional investigation—Jane’s distress, climaxing in her suspicion of him—had brought him through a conclusive mental process. There had been a robbery and a peculiar one. Money, bonds and valuable jewelry had been passed by in the theft of an unnamed something vitally precious to a girl whom he had offered to befriend.

Already much valuable time had been lost through Mrs. Sturgis’ incertitude, her summons of Jane and Jane’s unwitting summons of himself. His impulsive participation was delaying the more expert search which should have been instigated at once. The thief might have escaped through his interposition of himself. He felt that he ought to make amends if the time for such had not already passed.

Through this mental summary, accomplished during the moment that followed the matron’s demand, Pape managed the appearance of a man in deep study. At its conclusion——

“Looks like an inside job,” he declared.

“By inside you mean— Please don’t suspect any one within my household.” Mrs. Sturgis’ color rose with the advice.

“I have no right to suspect any one—not yet, madam. I am considering only known facts. Your safe has been robbed within the last few hours of the contents of this heirloom snuff-box. I assume, Miss Lauderdale, that you are ready to swear your treasure was inside the box when you entrusted it to your aunt?”

“You may—” Jane crisply. “I am not given to figments of the imagination.”

“I congratulate you, miss. The safe was opened by no ordinary robber, as proved by the valuables left. Somebody who appreciated the contents of—of Miss Lauderdale’s treasure committed the theft and in such a hurry that he or she did not wait to extract the contents, but took box and all. Later this person, not knowing that Mrs. Sturgis had been to the safe in the meantime and discovered the loss, found opportunity to replace the now-empty box and, in the hurry of closing the door, jarred the mechanism of the lock.”

Mrs. Sturgis nodded; looked really quite encouraged. “That could have been done while I went up stairs to dress after sending to the Metropolitan for my niece. But I do hope you’re not going to make the mistake of accusing my servants. They’ve been with me for years.”

“I am not going to accuse any one, although servants have a way of making less honest friends who use them. I simply say that no professional turned this trick. The case is one for Central Office men. Even if it were in my line, I could not, under the circumstances, take the responsibility of it myself.”
