"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 misstep 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.

. . . . . . . . . . . .

"Mr. Stanton's whereabouts are not even known to his most intimate friends. He sailed from this country most unexpectedly on the eighteenth of July a year ago, which was the day after the murder of Mr. Hasbrouck. It looks like a flight, especially as he has failed to maintain open communication even with his relatives. Was he the man who shot Mr. Hasbrouck? No; but he was the man who put the pistol in Dr. Zabriskie's hand that night, and, whether he did this with purpose or not, was evidently so alarmed at the catastrophe which followed that he took the first outgoing steamer to Europe. So far, all is clear, but there are mysteries yet to be solved, which will require my utmost tact. What if I should seek out the gentleman with whose name that of Mrs. Zabriskie has been linked, and see If I can in any way connect him with Mr. Stanton or the events of that night?

. . . . . . . . . . . .

"Eureka! I have discovered that Mr. Stanton cherished a mortal hatred for the gentleman above mentioned. It was a covert feeling, but no less deadly on that account; and while it never led him into any extravagances, it was of force sufficient to account for many a secret misfortune which happened to that gentleman. Now, if I can prove he was the Mephistopheles who whispered insinuations into the ear of our blind Faust, I may strike a fact that will lead me out of this maze.

"But how can I approach secrets so delicate without compromising the woman I feel bound to respect, if only for the devoted love she manifests for her unhappy husband!
