"I—-I don't know."

"Don't know? Haven't you been there?"

"Yes; but I didn't ask——-"

"Danny, you act as though you were loco. (crazy). What on earth is up? You went to call on Miss Preston. You reached the house, and evidently you left there again. But you don't know whether Miss Preston was in; you forgot to ask. Let me look in at the answer to the riddle."

"Dave—-Miss Preston is going to be married!"

"Most girls are going to be," Darrin replied quietly. "Do you mean that Miss Preston is going to marry some one else than yourself?"

"Yes."

"Soon?"
