'What is it?'I asked,with a cold fear in my heart.

Stapleton had a strange look on his face.'The people say it's the Hound of the Baskervilles,which is calling for some thing to hunt and kill.I've heard it once or twice before,but never so loud.'

'You are a man of science,'  Jordan 4.5 Mixed Air Force One  I said.'You don't believe that,do you? Isn't there a natural explanation for the sound?'

'A marsh makes strange noises sometimes.It is the water and the wet ground moving.'

'But that was the voice of a living creature,'I said.

'Well,perhaps it was.There are some very unusual birds on the moors.It was most probably the cry of one of those.'

At that moment a small butterfly flew across the path in front of us.'Excuse me,Dr Watson,'shouted Stapleton,and ran off to try to catch the butterfly.He ran quickly and fol lowed the butterfly on to the marsh, but he knew exactly where he could go,and was not in any danger.

As I watched him,I heard the sound of steps behind me. Jordan 4 Mixed Air Force One ,I turned and saw a woman near me on the path.I was sure she was Miss Stapleton.She was very beautiful.She was dark and tall,with a lovely face.Before I could say anything,she said:

'Go back!Go straight back to London,immediately.I can not tell you why,but please do what I ask you,and never come near the moor again.But my brother is coming.Not a word to him.'

Stapleton had caught the butterfly,and was walking bath to us.

'Hello,my dear,'he said to his sister,but it seemed to me that his voice was not completely friendly.' Jordans  shoe ,I see that you two have already introduced yourselves.'

'Yes,'she said.'I was telling Sir Henry that it was rather late in the year for him to see the true beauty of the moor.'

'I am sorry,'I said.'You have made a mistake.I'm not Sir Henry.I am a friend who is visiting him,and my name is Dr Watson.'

Miss Stapleton was clearly angry with herself.'I'm sorry,' she said.'Please forget what I said.But do come with us to our house.'
