And now, for a few hours, the whole interest of our narrative centres in her whom that moment had so completely transformed and made already a murderess in heart and in purpose. And how thoroughly must that heart have been steeled, and how entire must have been the banishment of all counteracting feelings, when she could for a whole day, in the midst of a household of fellow-servants, and under the watchful eyes of an angry mistress, continue to discharge her usual tasks, bearing this deadly purpose in her breast, yet never, by word, look, or gesture, betray the slightest indication of its dreadful secret,--no, not even so much as to draw suspicion toward herself after the discovery of the crime! There was no time or opportunity for preparation, of which little was indeed necessary; for human life is a frail thing, and a determined hand is always strong. She had already undergone the most effectual preparation for such a task,--that of the soul; and when that is once thoroughly accomplished, not much more is needed: a fact which seems not to be understood by those patriotic assassins--French and Italian--whose elaborately contrived infernal-machines do but betray the anxious precautions taken to insure lives which, according to their own professions, have been rendered valueless by tyranny, and ought therefore to be the more freely risked. Felton and Charlotte Corday understood their business better; but even their preparations may be called elaborate, compared with those of this poor slave-girl.
