The case for genre-specific copy-editors:

Pride and Prejudice and Zombies aside, in a Regency novel, the relatives of a recently deceased English peer should not generally be concerned about an entrail.

Well, I guess it depends how the peer died, doesn't it? There are situations in which one could be legitimately concerned about whether there was an entrail on the estate...

...okay, maybe not. I suspect that the copy-editor didn't know that "entail" could be a noun.

Surely only to the extent of instructing the staff to see that it is removed?

But no, you are undoubtedly correct.
