"Is it something exciting?" asked Zoe, her bright eyes glancing from one to another of the three.

"Very!" replied the inspector. "A robbery at Mr. Megger's chambers!"

"Come right along!" said Zoe. "I'm glad I didn't miss this!" And the odd trio departed forthwith.

"Can I come in?" she asked, with characteristic disregard of the conventional, as her luxuriously appointed car pulled up in Victoria Street.

"I should greatly prefer that you did not, Miss Oppner!" said Pepys quietly.

"That's unkind! Why mayn't I?"

"I have a reason, believe me. If you will carry out your original plan and go on to join Mr. Oppner, it will be better."

She met the gaze of his earnest eyes frankly.

"All right!" she agreed. "But will you come to the hotel to-morrow, Inspector, and tell me all about it?"

"If you will inform no one of the appointment and arrange to be alone—yes, at eleven o'clock!"
