All of the jigsaw readings in the following folders are in sets of three, i.e. there are 3 different texts. The common factor in all of them is that they are (usually murder) cases to be solved by the students in your class, who have been asked by an overworked Sherlock Holmes to help him out. Each of the texts in each set contains different information; when this information is shared, it is possible  to work out what happened. As you will see, the texts take the form of letters to Sherlock Holmes or newspaper reports.
