"Dining out with friends. Why?"
"Will you see him to-night?"
"I can if necessary."
"Do. Tell him to come down to my room as near eight o'clock to-morrow morning as he can. I've changed my mind."
"Oh!" cried Helen joyously. "Then you've concluded I'm right, after all?"
"No," said Darrow; "but if this thing carries out to its logical conclusion, I'm going to need a good bull-terrier pup!"
