“I suppose I shall have to tell you.  Being a detective, you have learned to keep your mouth shut.  Here is the whole story:  As I told you, I had a friend in the State Department.  Well, I went to him and, for old times’ sake, he tried to help, and did.  When I told him my story, he believed me, but he very frankly informed me that the matter was a delicate one and that, officially, he could do nothing.  He wasn’t entirely ignorant of the young Italian, but he said that would probably have to be ‘forgotten.’  He pointed out that the body had disappeared, that the man was absolutely unknown here, and that to prove murder would be practically impossible.  Still, he agreed that our knowledge of the murder would be a powerful help toward making His Excellency reasonable.  He outlined how that game should be played, and before I left he had arranged for someone to meet the Minister at the banquet that night, and delicately suggest that the State Department had had some inquiry regarding the disappearance of a brilliant young Italian officer.  Knowing what would happen at the banquet, I was ready to meet the Minister.  But it wasn’t necessary to rely wholly on that.  Late that night—­after my return from Brookland—­my friend sent for me to come to him at once.  I went, and he showed me the translation of a cipher-dispatch which had just been received from Europe.  That dispatch gave information concerning a dangerous situation which might lead to war.  It was very long, and dwelt also on the situation in a certain Grand Duchy, the ruler of which had just died.  The next in line, a girl, had disappeared.  The King was worried.  With war almost on his hands, he did not want the girl to take the throne, but rather desired the succession of her uncle, who was a strong soldier and just the man for the emergency.  The dispatch left it plainly to be understood that the girl was in America, and that the King would be glad if she remained here permanently—­in other words, that she be allowed quietly to disappear.  It was a cold-blooded proposition to deprive her of her rights, or to find some means of doing it.  Our own military attache at the royal capital secured the information; and, since America had been mentioned, thought it his duty to forward the dispatch to our State Department.  As soon as my friend had read it, he sent for me.  He put me under a pledge of secrecy until the matter was settled.  It has been settled now; but there is no need of the story going any farther than yourself.  ‘Since the girl has died,’ said my friend, ’the wishes of the King may easily be obeyed.  The uncle will ascend the throne, and the Duchy will remain an ally of the Kingdom.  This information should be in the hands of the Minister now and, instead of trying to prove that the lady is the Grand Duchess, he will probably be only too anxious to be rid of her.’  I had all that information,” continued Father Murray, “when I went to find you gentlemen and save you from getting into mischief.”
