“Light at last. I have seen Harry, and, by means known only to the police, have succeeded in making him talk. His story is substantially this: That on the night so often mentioned, he packed his master’s portmanteau at eight o’clock and at ten called a carriage and rode with the Doctor to the Twenty-ninth Street station. He was told to buy tickets for Poughkeepsie where his master had been called in consultation, and having done this, hurried back to join his master on the platform. They had walked together as far as the cars, and Dr. Zabriskie was just stepping on to the train when a man pushed himself hurriedly between them and whispered something into his master’s ear, which caused him to fall back and lose his footing. Dr. Zabriskie’s body slid half under the car, but he was withdrawn before any harm was done, though the cars gave a lurch at that moment which must have frightened him exceedingly, for his face was white when he rose to his feet, and when Harry offered to assist him again on to the train, he refused to go and said he would return home and not attempt to ride to Poughkeepsie that night. “The gentleman, whom Harry now saw to be Mr. Stanton, an intimate friend of Dr. Zabriskie, smiled very queerly at this, and taking the Doctor’s arm led him away to a carriage. Harry naturally followed them, but the Doctor, hearing his steps, turned and bade him, in a very peremptory tone, to take the omnibus home, and then, as if on second thought, told him to go to Poughkeepsie in his stead and explain to the people there that he was too shaken up by his mis-step to do his duty, and that he would be with them next morning. This seemed strange to Harry, but he had no reasons for disobeying his master’s orders, and so rode to Poughkeepsie. But the Doctor did not follow him the next day; on the contrary he telegraphed for him to return, and when he got back dismissed him with a month’s wages. This ended Harry’s connection with the Zabriskie family. “A simple story bearing out what the wife has already told us; but it furnishes a link which may prove invaluable. Mr. Stanton, whose first name is Theodore, knows the real reason why Dr. Zabriskie returned home on the night of the seventeenth of July, 1851. Mr. Stanton, consequently, I must see, and this shall be my business to-morrow. “Checkmate! Theodore Stanton is not in this country. Though this points him out as the man from whom Dr. Zabriskie bought the pistol, it does not facilitate my work, which is becoming more and more difficult. * * * * *
