“Of course. But is there nothing else that I can do? These German agents-why can you not have them arrested?”

“For various reasons. The best way you can help me is to take this message for me.”

The Frenchman stuck out his jaw aggressively. “It is ridiculous!” he burst out and then lowered his voice to a fierce whisper. “Discretion is necessary. I understand that. You are of the British secret service. One does not confide these things but I am not a fool. Very well! Why do we not together shoot down these filthy Bosches and escape? I have my revolver and together.…”

Graham jumped. “Did you say that you had a revolver-here?”

Mathis looked defiant. “Certainly I have a revolver. Why not? In Turkey …”

Graham seized his arm. “Then you can do something more to help me.”

Mathis scowled impatiently. “What is that?”

“Let me buy your revolver from you.”

“You mean you are unarmed?”

“My own revolver was stolen. How much will you take for yours?”
