Before God, who hears you, are you innocent of the theft of the bank-note ?" "Before God, who hears me," Isabel answered, "I am innocent." Lady Lydiard looked once more at the lawyer, and waited to hear if he believed _that_.
Mr.Troy took refuge in dumb diplomacy--he made a low bow.

It might have meant that he believed Isabel, or it might have meant that he modestly withdrew his own opinion into the background.

Lady Lydiard did not condescend to inquire what it meant.
"The sooner we bring this painful scene to an end the better," she said.
"I shall be glad to avail myself of your professional assistance, Mr.
Troy, within certain limits.

Outside of my house, I beg that you will spare no trouble in tracing the lost money to the person who has really stolen it.

Inside of my house, I must positively request that the disappearance of the note may never be alluded to, in any way whatever, until your inquiries have been successful in discovering the thief.
