5 ВОПРОСОВ К ТЕКСТУ, ПОЖАЛУЙСТА, РЕБЯТ, ХЭЛП

it was a dull and rainy day. The house was as melancholy as the weather. Everything was gloomy around and i had a feeling that something terrible would happen soon.

All was silent there and i could not find any trace of the unknown man. As i was walking back i was overtaken by Dr Mortimer. He was returning from one of distant farms. He told me that he was much troubled, for his little spaniel had disappeared on the moor. I remembered the pony on the Grimpen Mire and said nothing.
