First of all I want to tell you that my best friend's name is Igor and he is 15. He is the best person I have ever met. A few  words about his appearance. His height is nearly 149 cm. But he'd like to be a bit taller.  Igor has a round face as everyone has, a bit long nose and big cheerful grey eyes. His forehead is open.  His hair isn't very short but it's not long either. It is straight and black.  I think that he looks like his father. Igor is very active and creative, cheerful and curious. But the best thing is that he is reliable. We spend much time together. We go for a walk, we play tennis, watch TV, do things which we like. I love my friend.    Прежде всего, я хочу сказать вам, что моего друга зовут Игорь и ему 15. Она самый лучший человек, которого я когда-либо встречал. Несколько слов об его внешности. Его рост около 149 см. Но он хотел бы быть немного выше. 
У Игоря круглое лицо, как и у всех, немного длинный нос и большие радостные серые глаза.  Eго лоб открытый.   Его волосы не очень короткие, но это не длинные. Они прямые и  черные. Я думаю, что он похож на своего отца. Игорь очень активный и творческий, жизнерадостный и любознательный. Но самое главное - он надежный. Мы проводим много времени вместе. Мы ходим гулять, играем в теннис, смотрим телевизор, делаем вещи, которые нам нравятся. Я люблю моего друга.

A When I got to the top of the hill the sun was already going down. The hillsides below me were golden- green on one side and grey shadow on the other. There was no sound and nothing moved on the moor. One

great grey bird flew over my head. He and I seemed to be the only living things between the blue sky and the  empty land. But down below me there was a circle of old stone huts. * One of these still had enough roof to

keep a person dry when the weather was bad. My heart jumped as I saw it. This must be the stranger's hiding place - I could now find out his secret!

B

A little path through the rocks took me down to the door. Everything was quiet. The man might be waiting  inside, or he might be outside on the moor. I closed my hand on the gun in my pocket , walked quickly to the

door and looked in. The hut was empty.

But I was right. This was the place where the man lived. Some blankets in a corner showed me where he  slept. I could see the ashes of a fire in the old fireplace. Next to it there were some cooking pots and a bucket  of water . Empty tins were lying on the floor, so I knew that someone had used the place for several days. An  old table stood in the middle of the hut, and on this I found a small bag. Inside there was some bread, some  tins of meat and two tins of fruit.  Then I noticed a piece of paper under the bag. I picked it up and read it. It said. "Dr Watson has gone to  Coombe Tracey

: This secret man was collecting information about me! Who was he? What was he doing here?  Was he my enemy? I knew I could not leave the hut until I had answers to these questions.
