The Inspector looked thoughtfully at the end of the fresh cigar which he had just lit. “Well,” he said, “I don’t know that there was anything definite in my mind, only it seems a little strange that you and Miss Penelope Morse should both have been acquainted with the murdered man and that you should have come across one another.” “Sort of bond between us, eh?” Mr. Coulson replied. “She seemed a very charming young lady. Cut above Fynes, I should think.” The detective smiled. “All your American young ladies who come over here are charming,” he said. “Goodbye, Mr. Coulson, and many thanks!” The Inspector passed out, and the man whom he had come to visit, after a moment’s hesitation, resumed his seat. “These aren’t American methods,” he muttered to himself. “I don’t understand them.

A COMMISSION Mr. Robert Blaine-Harvey, American Ambassador and Plenipotentiary Extraordinary to England, was a man of great culture, surprising personal gifts, and with a diplomatic instinct which amounted almost to genius. And yet there were times when he was puzzled. For at least half an hour he had been sitting in his great library, looking across the Park, and trying to make up his mind on a very important matter. It seemed to him that he was face to face with what amounted almost to a crisis in his career. His two years at the Court of St. James had been pleasant and uneventful enough. The small questions which had presented themselves for adjustment between the two countries were, after all, of no particular importance and were easily arranged. The days seemed to have gone by for that over-strained sensitiveness which was continually giving rise to senseless bickerings, when every trilling breeze seemed to fan the smouldering fires of jealousy. The two great English-speaking nations appeared finally to have realized the absolute folly of continual disputes between countries whose destiny and ideals were so completely in accord and whose interests were, in the main, identical. A period of absolute friendliness had ensued. And now there had come this little cloud. It was small enough at present, but Mr. Harvey was not the one to overlook its sinister possibilities. Two citizens of his country had been barbarously murdered within the space of a few hours, one in the heart of the most thickly populated capital in the world, and there was a certain significance attached to this fact which the Ambassador himself and those others at Washington perfectly well realized. He
