The Secret Service is a strange group. They don't really have a leader. It's not set up like a military. Each one is supposed to be able to act like a leader when something comes up.
“Hear the words of prudence, give heed unto her counsels, and store them in thine heart; her maxims are universal, and all the virtues lean upon her; she is the guide and the mistress of human life.”
“Her face betokened all things dear and good, The light of somewhat yet to come was there Asleep, and waiting for the opening day, When childish thoughts, like flowers would drift away.”
