"You don't dare. You were merely bluffing when you mentioned the strelska. If you tortured us, you would have to answer to Ivan Saranoff on his return."

"How did you know that he is—" The Russian paused and bit his lip. "Shall I tell him that you refuse to talk?"

"When he returns, you may tell him that I will be glad to talk frankly with him. I came to Russia for that purpose, but I will not talk with one of his underlings. In the meanwhile, we are having lovely weather for this time of year, aren't we?"

With a muttered curse the Russian rose and left the room. Carnes turned to Dr. Bird.

"How did you know that Saranoff was away?" he demanded.

"I didn't," replied Dr. Bird with a chuckle, "it was merely a shrewd guess. We have twisted his tail so often that I figured he could not resist the temptation to come here and gloat a few gloats over us if he were here. I know his ruthless methods in dealing with his subordinates and I knew that they would never dare to resort to torture in his absence. No, old dear, we are safe until he returns. I hope he stays away a long time."

Four days passed monotonously. Three times a day the Russian girl appeared with ample meals. Despite their attempts to engage her in conversation, not a word would she reply or give any indication that she either heard or understood their remarks. The bearded Russian appeared daily and tried to question them, but Dr. Bird laughed at his threats and reaffirmed his intention of talking to no one but Saranoff.

"Your chance will soon come," replied the Russian with an evil leer on the fourth day. "He will be here the day after to-morrow. He will be able to make you talk."

"If he's telling the truth, the jig's about up," said Dr. Bird when the Russian had left. "I don't fancy that Saranoff will show us much mercy when he finds out what we've attempted to do."

"How would it be to overpower our waitress and make a break?" asked McCready in a guarded whisper.
