To clarify, in Chapter 6, Holmes lays out his plan for Watson, but he doesn't explicitly mention Henry Baskerville. Here's a summary of Holmes's instructions:
* Watson's Role: Holmes assigns Watson the role of "a harmless, amiable, middle-aged gentleman" who is a close friend of Sir Henry Baskerville and will stay at Baskerville Hall to keep an eye on him and the situation.
* Gathering Information: Watson is tasked with keeping a watchful eye on Sir Henry, learning about his routines, and discreetly observing any unusual happenings at the Hall.
* Maintaining a Low Profile: Watson must be careful not to arouse suspicion and avoid revealing their true purpose to anyone.
* Communication with Holmes: Watson will be in constant communication with Holmes, reporting any significant developments, and receiving further instructions from him.
Holmes's primary aim in Chapter 6 is to establish a foundation for their investigation and ensure that they have a safe and secure base of operations at Baskerville Hall.
