Annie Nodes was found dead in one of the bedrooms by her servant, Wilfred. Wilfred tells the story to the detective Sherlock Holmes: As soon as I finished the work I noticed that her study light was on and so I decided to peek in to check if she was in there. There was frost all over the window and so I wiped it away to see inside. That is when I saw her body and I immediately kicked open the front door. I called the police immediately afterwards. After listening to the entire story, Sherlock Holmes could immediately discover that the killer was the servant. Guess How?



As it was told in the above line that Sherlock Holmes was an detective he listen the whole story than he know that the killer was the servant but in the first line only it was told that Annie Nodes was found dead by her servant, so in first line only we can understood that the killer was servant.
