Steve was in no mood to-night to pick a quarrel and he passed the older fellow with averted eyes, dimly aware of the scowl that greeted him.

When he knocked at the instructor's door there was no reply and, after a moment, Steve turned the knob and entered.

At the outer door Eric had paused and looked back.
Mr.Daley's study was lighted but empty.

Satisfying himself on the latter point, Steve turned to go out.

Then, reflecting that, since the instructor had left the lights on, he was probably coming right back, he decided to await him.
