As for Frank, he met that look squarely, and between him and the eavesdropper at the transom a silent battle took place.
Dade and Dick suddenly knew this battle was occurring. They felt the strain and intensity of it, and they seemed to realize that the master mind would conquer. Neither of them moved, fearing to break the spell. Both felt that they could not move if they so desired.
For at least a full minute the duel of eyes continued. The mysterious man outside seemed putting all his strength of soul and will into the struggle.
Was it a flickering flare of the gas jet, or did the midnight eyes waver the least bit?
Without moving his head or his body, Dade Morgan turned his glance toward Merriwell. What he saw in Frank's face gave him a feeling of relief and unspeakable satisfaction.
Merriwell wore the look of a conqueror. He was the same undaunted, undismayed Merry as of old. He was master of this mysterious foe beyond the closed door.
Again Morgan lifted his eyes to the midnight orbs beyond the transom. A sensation of triumph thrilled him like an electric shock.
The deadly eyes wavered!
The silent duel was ended!
Something like a muttered curse and a choking cry of rage came from the lips of the man beyond the door.
