"To recover the blue diamond."
"Certainly; because the one discovered in Herr Bleichen's tooth-powder flask was not the real one."
"Just so. The real one was posted by the blonde lady. I had an exact copy made; and as, at that time, I had designs upon the Comtesse de Crozon's other jewels and as the Austrian consul was already under suspicion, the aforesaid blonde lady, lest she should be suspected in her turn, slipped the imitation diamond into the aforesaid consul's luggage."
"While you kept the real one."
"Quite right."
"I want that diamond."
"Impossible. I'm sorry."
"I have promised it to the Comtesse de Crozon. I mean to have it."
"How can you have it, seeing that it's in my possession?"
