What is the author's tone in The Undertaking: Life Studies from the Dismal Trade by Thomas Lynch?

Thomas Lynch is both a poet and an undertaker. As such, one can imagine that the tone of The Undertaking might be dark, dramatic and serious. Not so. This is not to say that Lynch ignores dark events, murders, rapes, the disgusting corpses that he must dispose of or piece back together. It is also not to say that Lynch thinks that death and dying are light-hearted matters not to be taken seriously.
