It is all in your hands, Mademoiselle.

You can tell me where the flag is." Hamilton smiled again with exquisite cruelty.
Farnsworth stood by gazing upon Alice in open admiration.

Her presence had power in it, to which he was very susceptible.
"You look like a low, dishonorable, soulless tyrant," she said to Hamilton, "and if you get my flag, how shall I know that you will keep your promise and let Papa Roussillon go free ?" "I am sorry to say that you will have to trust me, unless you'll take Captain Farnsworth for security.

The Captain is a gentleman, I assure you.

Will you stand good for my veracity and sincerity, Captain Farnsworth ?" The young man smiled and bowed.
Alice felt the irony; and her perfectly frank nature preferred to trust rather than distrust the sincerity of others.
