In "A Name for the City" and again in Requiem for a Nun, this bandit is part of the gang that is brought to the settlement; he claims that the sergeant who commanded the militia unit that captured him was "a former follower of his, the bandit's, trade" (5, 201).
In The Town this bailiff "hollers 'Order! Order in the court!'" at Mink Snopes' murder trial when Mink calls for Flem instead of paying attention to the proceedings (86).
In The Hamlet this bailiff tries to serve Flem his papers for a court appearance and is baffled when Flem refuses to acknowledge the suit against him (355).
In Requiem for a Nun, the "Bailiff" who commands "Order in the court!" in the play's brief first scene is not described at all (41). Our assumptions about his gender, race and class are based on the bailiffs who appear in courtrooms in other Yoknapatawpha fictions. We also assume that the "MAN'S VOICE" that opens the play, telling "the prisoner" from behind the theatrical curtain to "stand," also belongs to this Bailiff (38).
The 'bailiff' who appears in Intruder in the Dust is a product of Chick Mallison's imagination, as he fantasizes about how the character of the white population of Beat Four might be put on trial.
When The Town retells the story of Byron Snopes' robbery at the Sartoris bank, it adds these two auditors to the account; they quickly discover the crime.
In the three texts that tell the story of Flem Snopes' attempted embezzlement - "Centaur in Brass," The Town and The Mansion - these are the accountants employed by the state, or perhaps the company that bonds local officials, to audit the books at the Jefferson power plant. The third text revises the account to add that their figures are incorrect.
The narrator of Flags in the Dust notes that the Benbow house in Jefferson, and its large lawn and drive, were designed by "an English architect of the '40s" (e.g. the 1840s, 163). In other texts, the Old Frenchman place in the county was designed by an English architect at about the same time, but there's no indication that it was the same man.
