Hello, I'm HolmesPlease go, sir. And close the door behind you
Hello I'm Dr Grimesby RoylottMy stepdaughter was here. I followed her. What did she say to you?
I will decide the time to leave, Do not come near my stepdaughter or... I am a dangerous man when I am angry.
No, never.
I don't know. I've never seen my stepfather open it. No. Perhaps the milk is for the tiger
¿Your sister use the bell?Hmm, a bell, but it doesn't ring," he said.Now, why is this cord here?The cord went up to a small ventilator. The ventilator goes to Dr Roylott's room, he said. "That is very strange - most ventilators go outside.
You must listen carefully. There is a hotel in the other side of the street, Watson and I can see the house from the hotel, when your stepfather goes to bed, put a lamp next to the window. When we see the light we will come to the house
Okay, perfect.
¿What's in the metal safe? ¿Have you got a cat?
The next day...
What about the bang of metal that Helen Stoner heard?
How did you know that the snake was in the room?
And so it went back through the ventilator
It returned to Dr Roylott. Of course, the snake was furious alter I hit it. It bit the first person it saw, Dr Roylott, its owner. In a way, I am responsable for the death
I heard the snake hiss when it came through the ventilator. When it came down the cord, I hit it with the stick
That was the metal door of the safe, said Holmes. "Dr Roylott closed it after he put the snake in the safe again.
Dr Roylott trained the snake to return to him when it heard him whistle. The milk on the sale was a reward for the snake
