In spite of his fifty years, he still possessed unusual strength, whilst his adversary was apparently in a weak condition. But the struggle was a brief one. Arsène Lupin made only a slight movement, and, as suddenly as he had made the attack, Ganimard released his hold. His right arm fell inert, useless.

“If you had taken lessons in jiujitsu at the quai des Orfèvres ,” said Lupin, “you would know that that blow is called udi-shi-ghi in Japanese. A second more, and I would have broken your arm and that would have been just what you deserve. I am surprised that you, an old friend whom I respect and before whom I voluntarily expose my incognito, should abuse my confidence in that violent manner. It is unworthy⁠—Ah! What’s the matter?”
