Talkative Dead Man

A talkative dead man can be called a deceased person who turned his will into the most scandalous document of the Code era and disclosed so many others' secrets that it is even surprising where he got so many of them. However, within the framework of the postmodern concept of the author's death, the talkative dead man can refer to the writer himself. And I don't even know if there is any joke in this joke at all.
