We must move back to higher ground above the fog

The moon was shining on the Great Grimpen Marsh,and a fog was rising from it Holertmes watched the fog and began to loyuiok worried The fog was creeping up from the mawewersh towards the house.ghjWe were hidden near the path,which was on the far side of the house from the marsh.
"The fog is moving towards us,Watson,and that is very serious,"said Holmes."It is the one thing that could make my plans go wrong."
As we watched,the fog,which had crept as far as the house,began to flow round it.Angrily Holmes sdfock in front of us with his open hand.
"If Sir Henry doesn"t come out in the next quarter of an hour,the path will be covered by the fog.In half an hour we shall not be able to see our hands in front of our faces.We must move back to higher ground above the fog."
