The woman was no woman at all! It was a man in disguise!

Merry literally gasped for a single instant, but he recovered at once.

Through his head flashed a thought:

“This must be some criminal who is seeking to escape justice!”

“The motion of the train is rather trying to one who is not accustomed to it,” he said. “Some people feel it quite as much as if they were on a vessel. Car sickness and seasickness are practically the same thing.”

She looked at him through the concealing veil, but did not speak.

“I have traveled considerable,” he pursued, “but, fortunately, I have been troubled very little with sickness, either on sea or land.”

“Will you be kind enough to leave me!” came from behind the veil, in accents of mingled imploration and anger.

“I could not think of such a thing, madam!” he bowed, as gallantly as possible. “It is my duty to remain and see that you come to no harm.”
