“Why are you so astonished?” asked Marion, as the three girls locked arms and sauntered up the street.
“Because I cannot imagine a mystery connected with such a very practical person as yourself,” returned Janet.
“Tell us what it is,” urged Phœbe, “for then it will remain a mystery no longer.”
“Oh, yes it will,” declared Marion, rather soberly. “I’ve no solution to offer. All I can do is tell you what I saw, and allow you to solve the mystery yourselves.”
“What did you see, then?” inquired Janet, curiously.
“A ghost.”
“A ghost! Why, Marion!”
“Of course, my dears, there is no such thing as a ghost, although, as I say, I saw it plainly. Otherwise I should have called it an ‘apparition’ instead of a ‘mystery’.”
“To be sure.”
“But if I saw a ghost, and ghosts are impossible, then I am in touch with a mystery,” she continued. “Do you follow my logic, girls?”
