They walked to the end of the gymnasium building, where, in a long room, the bicycles of the students were kept. It was pitch dark inside and not a soul was in sight.
"Now, you remain outside," said Ritter. "If you see anybody coming begin to whistle 'Yankee Doodle,' as loud as you can. Don't wait for me, for I'll go out the back way."
"All right. But let me know when you are through," answered Coulter, somewhat nervously.
"Sure."
Coulter took his stand outside of the building and peered forth eagerly in the darkness. Only three cadets were in view and they presently entered the school building. Then ten minutes went by—a long wait for the youth who was aiding Ritter in his plot. Then Reff came quickly from the gymnasium.
"Anybody around?" he asked hurriedly.
"No."
"Good enough."
"Have you finished, Reff?"
"Yes."
