"With whom?"

"This Sister."

Lady Ruth surveys the other from her vail to the hem of her dress.

"I would advise you not to do so, doctor."

"Why do you say that?" he asks, astonished.

"Because you will regret it, because you are being made the victim of
another plot."

"Lady Ruth, do I hear aright? Do you fully realize what it is you say?"

"I am conscious of the gravity of the charge, but that does not prevent
me from asserting it. I repeat what I said before, that you are again
the victim of a plot. As to this Sister here, can it be possible you do
not know her?"

He shakes his head.

"Have you seen her face?"

"It is old and shriveled--that of a stranger."

At this the Sister throws back her vail, and they see the features John
describes.
