The murderer

We had four different options to choose from:Edith Summerson,Jack Spratt,General Wills and finally Eleanora Springston...I finally chose that the murderer was Edith Summerson because in the past week we have been looking for the murderer on the mountains and we used xara extreme 4 to trace the murderer and also we have been using a database to collect lots of information and put it in to one piece. We found out how many people there were that was staying at the mountain and what there name was and there last name and etc.and also we used the assignments laid for us while looking at the database and answering the questions and in the end we had the four people as the options and in the end I decided that the murderer was Edith Summerson.
