The Hound of the Baskervilles
- As Holmes, Watson, and Lestrade drive over to Merripit House, the suspense is killing Watson.
- Holmes and Lestrade hide about two hundred yards away from the house.
- Holmes sends Watson to spy through the dining-room window.
- Sir Henry and Stapleton are sitting together and smoking.
- Beryl's nowhere to be seen.
- The Grimpen Mire is covered with fog, which is a bummer for Holmes—fog is the one thing that could really endanger Sir Henry's life.
- They hear the sounds of Sir Henry leaving the house.
- And then, Holmes hushes Watson—there's another sound of pattering feet coming.
- It's a black hound covered in flickering flame, with fire coming out of its mouth.
- Oh no, it's running toward Sir Henry.
- Holmes and Watson shoot the dog, which howls but keeps running.
- Sir Henry is looking behind him at the dog—and he looks terrified. Duh. The dog leaps at Sir Henry and starts biting him. Bad dog!
- But Holmes catches up and empties his gun into the dog.
- The dog falls dead.
- Sir Henry faints, but he's still alive.
- When Sir Henry comes to, he, Holmes, and Watson inspect the body of the dog.
- It's an enormous beast with huge jaws, and it's been covered in some kind of weird glow-in-the-dark stuff.
- Watson touches the stuff on the dog's fur and realizes that it's phosphorus (a glowing chemical).
- Holmes apologizes for putting Sir Henry in so much danger—he didn't expect either the fog or the dog.
- Sir Henry's so freaked out that Holmes and Watson leave him sitting on a rock while they go off after Stapleton.
- Back at Merripit House, there's a locked bedroom door.
- Holmes breaks down the door. They find a woman bound and gagged: Beryl Stapleton.
- She's furious and heartbroken that Stapleton has been abusing her and using her as his tool in his schemes against Sir Henry.
- Beryl says that Stapleton has a hiding place in the middle of the Grimpen Mire. The fog is so dense that he won't be able to leave his hiding place that night.
- The next morning, Beryl leads Holmes, Watson, and Lestrade through the dangerous bog.
- As the three men walk deep into the Grimpen Mire, Holmes spots something: Sir Henry's black boot.
- Stapleton must have been using the boot to teach the hound to track Sir Henry's smell.
- But they don't find any other sign of Stapleton.
- Watson believes that Stapleton probably got lost in the fog that night and fell into the Mire, never to emerge.
- On the island in the Mire, they find traces of the dog: this must be where Stapleton kept it.
- Sadly, they also find the skeleton of Dr. Mortimer's little spaniel.
- There's a pot full of the glowing stuff that Stapleton had been using to create the fire-breathing "Hound of the Baskervilles," which frightened Selden into running over a cliff and scared Sir Charles to death.
