I wouldn't go near the haunted house if I were a certain 'Tirra-lirra'-singing knight...
I realized this was inspired by Tennyson's 'Lady of Shalott' and Emilie Autumn's 'Shalott' when I was deep into the sestina, and then it was too late to turn back.
My entry for Sestina-ween. Do I get cookies for iambic pentameter and not cheating with the end words? I certainly hope so.
Comments and critique appreciated.
