“Two!” repeated Raikes incredulously.

“Yes—but listen: I am anxious to hear the conclusion of that remarkable story you began last night.”

“But,” objected Raikes, “I have already told you all I know.”

“I am aware of that,” answered the detective, “but your friend, the Sepoy, will doubtless oblige you with the balance. Arrange with him at breakfast-time for a continuation. I will return either to-night or to-morrow morning to hear it.”

“But——” began Raikes.

“Do not refuse to do as I ask,” urged Gratz impressively. “It may be useful; I’m inclined to think it will.”

“Very well,” answered Raikes. “I will do as you suggest.”

“And,” continued Gratz, “I need not assure you that if a living soul learns of my presence here last night, I can do nothing for you.”

“I understand,” said Raikes.

“And I,” added Robert.
