When does it say You look like a general planning battle with his chief of the staff in hound baskervilles?

The phrase "You look like a general planning a battle with his chief of the staff" doesn't appear in Sir Arthur Conan Doyle's "The Hound of the Baskervilles."

It's possible you're remembering a scene from a different adaptation of the story, or perhaps a different work altogether.

Could you provide more context? For example:

* What character(s) are you referring to?

* What is the specific situation?

* Do you remember any other details about the scene?

With more information, I might be able to help you pinpoint the specific source of this phrase.
