"Then what is to be done?"

"I cannot say at present. If you will leave the pocket-book to me I will speak to Ellis, and we can come to some decision."

"Certainly I will give you the book," said Janet, rising. "I have every confidence in you and Dr. Ellis."

"Thank you. Would you mind explaining precisely how you came into possession of the pocket-book?"

"Not at all," said Janet, and she related, in a concise manner, how Hilda's prank with the desk had led to the discovery of the book.

Having given Cass all possible information, and answered all possible questions, Janet, tired out with her emotions, and with the unusual exercise, took her leave. Cass accompanied her to the door, and promised to inform her of all that should happen in connection with this new piece of evidence. Somewhat relieved, Janet went home to Myrtle Villa.

Immediately on the doctor's return, Cass showed him the pocket-book, and repeated Janet's story. Ellis, naturally enough, was as surprised as his friend, and discussed the matter with him at length. Finally, it was decided that Ellis should see Schwartz that same evening, and hear what he had to say for himself. Owing to the exigencies of his profession as critic, Harry could not accompany his friend. The doctor was not sorry, as he thought that he could get more out of Schwartz when alone with him than in the presence of a third person. He did not take the pocket-book with him lest it should be lost, for Schwartz was a determined man to deal with. As yet Ellis could hardly credit that he was guilty, and in spite of the damning evidence found by Janet he postponed, making up his mind until he heard what the German had to say for himself. In this frame of mind he started for the Merryman Music-Hail.

Schwartz was in his private room, and as Ellis had purposely arrived rather late he was at leisure at the time. So effusively did he welcome Ellis that the doctor felt almost ashamed of his errand, but, bracing himself up with the idea that Schwartz, if not the actual criminal, yet knew something about the crime, he managed to appear sufficiently stern. To the German's eager inquiries about Hilda's health and Hilda's eyesight he gave brief and monosyllabic replies. At last Schwartz was forced to take notice of his visitor's unfriendly attitude.

"What is not right, doctor?" he asked anxiously.

Ellis glanced round to see that the door was closed, and cleared his throat.
