'It is I,' Arthur said. 'I thought I smelled gas, and I have been hunting round for it. There is nothing worse to breathe than gas, whether from the furnace, the pipes, or the drain. I hope that is all right.'

'Yes,' Frank answered, a little crossly. 'Had a new one put in two weeks ago.'

'If there's gas in the main sewer it will come up just the same, and I am sure I smell it,' Arthur said. 'I think I shall have all the waste-pipes which connect with the drain cut off. Good-night. Am sorry I disturbed you.'

They heard him as he went across the hall to his room, and Frank was settling down again to sleep when there came a second knock, and Arthur said, in a whisper:

'I hope I do not trouble you, but I have decided to go myself to the station to meet Gretchen. She is very timid, and does not speak much English. Good-night once more, and pleasant dreams.'

To sleep now was impossible, and both husband and wife turned restlessly on their pillows, Frank wondering what ailed his brother, and Dolly wondering who Gretchen was and how her coming would affect them.


CHAPTER IX.

WHO IS GRETCHEN?

This was the question which Mr. and Mrs. Tracy asked of themselves and each other many times during the hours which intervened between their retiring and rising. But speculate as they might they could reach no satisfactory conclusion, and were obliged to wait for what the morning and the train might bring. The party had been a success, and Frank felt that his election to Congress was almost certain; but of what avail would all this be if he lost his foothold at Tracy Park, as he was sure to do if a woman appeared upon the scene. Both he and his wife had outgrown the life of eleven years ago, and could not go back to it without a struggle, and it is not strange if both wished that the troublesome brother had remained abroad instead of coming home so suddenly and disturbing all their plans. They heard him moving in his room before the clock struck six, and knew he was getting himself in readiness to meet the dreaded Gretchen. Then, long before the carriage came round they heard him in the hall opening the windows and admitting a gust of wind which blew their door open, and when Frank arose to shut it he saw the top of Arthur's broad-brimmed hat disappearing down the stairs.
