The crossbow acts as a symbol of the Welt family’s legacy of violence, deceit, and fraudulent claims to nobility, underscoring the novel’s thematic focus on The Manipulation of Truth Through Competing Narratives. As the weapon used to kill both Lawrence and Conrad Welt 20 years apart, it represents a repeating cycle of familial betrayal and murder that haunts Tithe Hall. This pattern positions the family’s corruption as an inherited trait, passed down from one generation to the next.

The manner of death, a bolt to the eye, deliberately echoes the fabled death of King Harold Godwinson at the Battle of Hastings, a connection the Viscount proudly (and falsely) claims as a family legend. He boasts that the weapon is “the very arrow that killed Harold Godwinson” (20). This claim is a crucial element of the family’s performance of aristocratic prestige, designed to invent a noble history where none exists. Miss Decima later debunks this lie, revealing the crossbow is merely a “fake […] another Welt trick to appear noble” (151), pointing to the ways the family manipulates the truth to reify their social position and influence. Ultimately, the crossbow serves as the murderers’ most effective red herring, a tool of misdirection that forces the investigation to focus on familial history and concealing the simple, mechanical truth of the Viscount’s murder.
