"Gone Mad" (Excerpt from Alias Grace by Margaret Atwood)

“Gone Mad” (Excerpt from Alias Grace by Margaret Atwood)

"Gone mad is what they say, and sometimes Run mad, as if mad is a different direction, like west; 
as if mad is a different house you could step into, or a separate country entirely. 
But when you go mad you don't go any other place, you stay where you are. And somebody else comes in."
