The mystery story:
Last night I _ (walk) home next to the river Thames, when something strange _ (happen) to me. It was late at night and I _ (have) a long and difficult day at work. There was a large full moon in the sky and everything was quiet. I was tired and lonely and I _ (just have) a few pints of beer in my local pub, so I decided to stop by the riverside and look at the moon for a while.
I _ (sit) on some steps very close to the water’s edge and looked up at the big yellow moon and wondered if it really was made of cheese. I felt very tired so I _ (close) my eyes and after a few minutes, I _ (fall) asleep. When I woke up, the moon _ (move) behind a cloud and it was very dark and cold. The wind _ (blow) and an owl _ (hoot) in a tree above me. I rubbed my eyes and started to get up, when suddenly I _ (hear) a splash. I _ (look) down at the water and saw something. Something terrible and frightening, and unlike anything I’d ever seen before. Something _ (come) out of the water and _ (move) towards me. Something green and strange and ugly. It was a long green arm and it _ (stretch) out from the water to grab my leg. I was so scared that I couldn’t move. I _ (never be) so scared in my whole life. The cold green hand _ (move) closer and closer when suddenly there was a blue flash and a strange noise from behind me. Someone _ (jump) onto the stairs next to me. He _ (wear) strange clothes and he had a crazy look in his eyes. He shouted “Get Back!” and _ (point) something at the monster in the water. There was a bright flash and the monster hissed and disappeared.
I looked up at the man. He looked strange, but kind. “Don’t fall asleep by the river when there’s a full moon”, he said “The Moon Goblins will get you.” I _ (never hear) of moon goblins before. I didn’t know what to do. “Who… who are you?” I asked him. “You can call me… The Doctor.” He said. I _ (try) to think of something else to say when he turned around and said, “Watch the stars at night, and be careful of the full moon”. I was trying to understand what he meant, when there was another blue flash and I closed my eyes. When I opened them again, he _ (go).
I couldn’t believe what _(happen). What on earth were Moon Goblins, and who was the mysterious Doctor? And why had he saved me? I was determined to find the answers to these strange questions. I stood up, looked at the moon and quickly walked home.
