He was all ready to go to his train when the Washington call came in, and as he hurried to his father's office to answer it he found his heart crying out to an Unseen Power to help in this trying hour and protect the sweet girl in awful peril. "Oh, God, I love her!" he found his heart saying over and over again, as if it had started out to be an individual by itself without his will or volition. There was no comfort from Washington Police Headquarters. Nothing more had been discovered save another crumpled postal lying along the roadside. They received with alacrity, however, Mr. Barnard's Washington hotel address, and the description of the young woman and her belongings. When Graham had finished the hasty conversation he had to fly to make his train, and when at last he lay back in his seat in the parlor car and let the waves of his anxiety and trouble roll over him he was almost overwhelmed. He had led a comparatively tranquil life for a young man who had never tried to steer clear of trouble, and this was the first great calamity that had ever come his way. Calamity? No, he would not own yet that it was a calamity. He was hurrying to her! He would find her! He would not allow himself to think that anything had befallen her. But wherever she was, if she was still alive, no matter how great her peril, he was sure she was praying now, and he would pray too! Yes, pray as she had taught him. Oh, God! If he only knew how to pray better! What was it she had said so often? "Whatsoever ye ask in my name"--yes, that was it--"I will do it." What was that talismanic Name? Ah! Christ! "Oh, God, in the name of Christ--" But when he came to the thought of her she was too exquisite and dear to be put into words, so his petition went up in spirit form, unframed by words to weight it down, wafted up by the pain of a soul in torture. At Baltimore it occurred to Graham to send a telegram to Barnard to meet him at the train, and when he got out at Union Station the first person he saw was Barnard, white and haggard, looking for him through the bars of the train gate. He grasped the young man's hand as if it were a last straw for a drowning man to cling to, and demanded in a shaking voice to know if he had heard anything from Miss Hollister. One of the first questions that Graham asked was whether Barnard had been back to the office where Miss Hollister had taken the dictation, to report her disappearance. "Well, no, I hadn't thought of that,"' said Barnard blankly. "What would they know about it? The fact is I was rather anxious to keep the facts from getting to them. You see they warned me that there were parties anxious to get hold of those specifications. It's Government work, you know." "They should know at once," said Graham sternly. "They may have inside information which would give us a clew to follow. The secret service men are onto a lot of things that we common mortals don't suspect."
