You are Dr. James Healey and last week you were a genius; but that was before the DNA experiments. Before the accident, you said it could never happen -- but since then you have felt your mind decaying, a little more each day. You have watched your wife slip into imbecility. You have seen the crowds growing murderous with animal terror, the president of the United States babbling and drooling on tv -- and only one thing separates you from them. You, at least, know what is happening, as you search for the cure for the horror you have unleashed upon the world -- and each day the dimming of your mind lowers your chance of finding it!
