"By whom?"
"By Mr. Jervas," he answered reluctantly.
"With Sir John's knowledge and consent?"
Aron glanced at me with an almost piteous expression.
"Sir John knew of it."
"But before it was opened, or afterwards?"
The answer was slow in coming, but it came at last.
"Afterwards."
"Then I take it," I resumed, "that Mr. Jervas Rookley robbed his father?"
I spoke in a loud tone, and Aron started from his seat, his eyes drawn towards the door. I rose from the sofa and opened it; there was no one in the passage, but I left the door open. When I turned back again I saw that Aron was looking at me in some perplexity, as if he wondered whether I knew.
