Read it through once

“Some ten or twelve, but none which present any feature of interest. They are important, you understand, without being interesting. Indeed, I have found that it is usually in unimportant matters that there is a field for the observation, and for the quick analysis of cause and effect which gives the charm to an investigation. The larger crimes are apt to be the simpler, for the bigger the crime the more obvious, as a rule, is the motive. In these cases, save for one rather intricate matter which has been referred to me from Marseilles, there is nothing which presents any features of interest. It is possible, however, that I may have something better before very many minutes are over, for this is one of my clients, or I am much mistaken.”
