He turned his eyes up toward it, then was about to lower them, when they saw something which caused him to start, to stop and to stare.
By this time he was near that part of the Park called the "ruins."
Right before him was the façade with the oriel window.
All the way up the hill, when not thinking of the "Blue Lion" and its mysterious frequenters, he had been thinking over the various ghost stories in connection with the Park, and now, just at the moment when the moon was obscured, and he was thinking of one of the latest he had heard, he saw something white pass across the window.
He stared and waited breathlessly.
"I'll take my oath I saw it," he muttered. "It's gone, and I mayn't see it again. But I saw it, I swear! Ah!"
The sharp, smothered exclamation was caused by absolute fear.
It had come again.
There, so plain and distinct that he could see every fold in the white robe, was the White Nun!
Jem's face turned pale and his teeth shook.
