Who is it?

Louise and Graham quickly wore their robes and made their way down the stairs as quickly as possible. Hearing the echo of the scream, some of the servants like Gilbert, Jonas, Philip, Meg and Emily had woken up in shock and had climbed out of bed and out of the servants quarters to see what happened. 

The servants stood in front of the dining room with a look of horror marred on their faces, unable to speak but just stare. 

"What is going on here? What was the scream about?" Graham asked in a worried tone. His eyes fell on the maids as the scream they heard sounded as if it was of a woman. 

Gilbert's already grave expression turned worse in complexion while he tried to keep a composed expression, "Master Graham… inside the dining room," said the butler. 

Louise wondered what had got the servants this shaken.
