“Your country should be proud of you,” he said in good English with a provoking sarcasm.

In fact, neither Jack nor Raynor looked at his best just then. Their caps were gone, lost in the struggle with the would-be robbers, their hair was tousled, perspiration streamed down their faces and their garments were torn and dusty.

Jack felt all this, and the knowledge of it did not tend to cheer him. Had he been a policeman and known no more of the facts than did the gendarmes, he felt that he would have been justified in acting in the same way. But he determined to try to explain the case.

“We are off the American tank steamer Ajax,” he said. “To-night we had an important errand in this section of the city. On our way back to the ship we heard screams, and investigated. We found three men trying to rob an old lady and a younger one who were seated in the closed part of a blue limousine.

“After a struggle we disarmed them and put them to flight. Just as you people came up, the chauffeur, who ran away during the fight, reappeared, jumped into his seat and drove off. We were in a hurry to get back to our ship and so, foolishly, as I can see now, we ran off, thinking that if we stayed we might be detained and questioned.”

“Is that all?” asked the officer calmly.

“That is all,” responded Jack.

“It is enough.”

“Enough for what?” The man’s tone nettled Jack in spite of himself.

“Enough to secure you both a lodging in the prison of the city to-night.”
