"You know, in case the worst I _have_ feared should happen, they will smother me. You need not smile. They will; they always do. My uncle will be full of horror, weakness, precipitation; and that is the only expedient which will suggest itself to him. Nobody in the house will be self-possessed but you. Now promise to befriend me--to keep Mr. Sympson away from me, not to let Henry come near, lest I should hurt him. Mind--_mind_ that you take care of yourself too. But I shall not injure you; I know I shall not. Lock the chamber door against the surgeons; turn them out if they get in. Let neither the young nor the old MacTurk lay a finger on me; nor Mr. Greaves, their colleague; and lastly, if I give trouble, with your own hand administer to me a strong narcotic--such a sure dose of laudanum as shall leave no mistake.
