"You treacherous, murderous scoundrel!"  I cried.  "How shall I deal with you?  You are as dangerous as a wild beast!  If I were to beat your brains out with the butt of this pistol I should only be treating you as you deserve!  And I will do it too as sure as you are lying there at my mercy, unless you will swear by all you hold sacred that you will never again attempt my life, and that you will set me ashore, free, at the first port at which we touch.  Will you swear that, or will you die?"
