Rolf turned fiercely on Frank, almost snarling:
"You must have been at the bottom of it all! Where is she?"
Frank was astonished, as his face plainly showed.
"Where is she?" he repeated.
"Whom do you mean, sir?"
"It is useless to pretend that you do not know. You must have found an opportunity to communicate with her somehow, although how you accomplished it is more than I understand."
"You are speaking in riddles. Say what you mean, man."
"I will. If you do not immediately tell us where she is, you will find yourself in serious trouble. Is that plain enough?"
A light came to Frank.
"Do you mean the Queen of Flowers?" he eagerly asked.
