Is there an idiom in The House of Dies Drear?

While there isn't a specific, commonly recognized idiom in the text of *The House of Dies Drear*, there are a few instances of phrases that could be considered idioms. It depends on how you define "idiom."

Here are some possibilities:

* "Let the dead bury their dead." This is a direct quote from the Bible (Matthew 8:22), but it functions as a proverb and is used in the book to convey a sense of detachment and resignation.

* "Hold your horses." This is a more common idiom, meaning to slow down or wait, and it's used by the narrator's father in the story.

* "Don't count your chickens before they're hatched." This is another common idiom, used to caution against making assumptions or celebrating too early. While not directly present in the text, the theme of the book (unrealistic expectations and the consequences) could be seen as embodying this idiom.

It's important to note that these instances are not necessarily unique to the book, and they don't have the same metaphorical impact as some well-known idioms.

Therefore, it's more accurate to say that *The House of Dies Drear* uses common phrases and proverbs rather than a specific, defining idiom.
