Fog(2)

'King street,'said Polly.
'Sorry,Miss,'replied the man,'the truth is that it is too foggy for thye bus to run that far.Take the Underground to Green Park.The weather might be better there and you might be able to get a taxi.'
A tall man
As polly observed the passengers on the trian,she had a feeling that she was being watched by a tall man in a dark overcoat.At last the train arrived at Green Park station.While the rest of the passengers were getting out,she glanced at the faces around her.The tall man was nowhere to be seen.

Footsteps
When Polly got to the station entrance, it was empty.Outside,wherever she looked the fog lay like a thick,grey clound.There was no one in sight.Polly set off towards Park Street.As she walked along the narrow street,she heard the street,the footsteps approaching,but by the time she reached the corner of the street,the footsteps approaching, but by the time she reached the corner of the street, the footsteps were gone.Suddenly Polly felt a rough hand brush her cheek, and she heard a man's voice in he ear saying 'Sorry'.The man moved away.She could feel her heart beating with fear.
