Oh what a tangled web we weave when first we practice to deceive
This words are the part of Wilton’s final speech from the poem “Marmion” by Sir Walter Scott. The main character of the poem is Lord Marmion, a charming womanizer, who is guilty of murdering one woman he got tired of (not by himself, though. He just revealed to the church that she was the nun that escaped the monastery to live with Marmion. She was walled alive and he was free to take another mistress). His new lover-to-be is Lady Clara, Wilton’s fiancee. Wilton has a duel with Marmion but loses and is disgraced. Finally, he manages to restore his honor and meet his sworn enemy on the battlefield. The quote above is the part of his accusation speech he throws to Marmion before the new duel starts.
