Peter Falk's "Columbo" and Mr. Bucket in Charles Dickens's "Bleak House"

Although "Columbo" ran throughout my childhood in the 1970s and I watched more than a few episodes, I don't remember anything about them except the personality of Peter Falk's title character – and his trick where he would turn around while he was leaving to ask the suspect "just one more thing." I was surprised to discover the same image in Charles Dickens's "Bleak House" (1853) at the end of a conversation between Sir Leicester Dedlock and the detective Mr. Bucket: "Mr. Bucket makes his three bows and is withdrawing when a forgotten point occurs to him." The difference is that Sir Leicester Dedlock is not the suspect in Mr. Bucket's case. (Andrew Shields, #111words, 24 August 2022)
