What is a theme statement of the poem "Upton Wood" by Wilson MacDonald?

Uptom Wood is a horror poem which somewhat portrays the ability of the dead to affect those who are alive.

Explanation:

The poem speaks to the execution by hanging of three thieves by a Law Enforcer who eventually becomes a victim of his own deeds through the loss of his daughter to what would seem the ghost of one of those who was executed.

A theme is a central thought which the writer intends for the reader to hold long after they are done with reading their work.

A theme statement is a statement which best describes that central thought or idea.

Cheers

im not sure about this one

as for symbolic actions, the narrator's tearing down the wallpaper in an attempt to find the "woman" in the wallpaper represents her struggle to retain or regain her sanity.   the wallpaper has been part of her confinement and by her tearing it down, she is freeing herself from that confinement.
