Quote by Sir Arthur Conan Doyle
Singularity is almost invariably a clue. The more featureless and commonplace a crime is, the more difficult is it to bring it home.
Summary
This quote suggests that "singularity," or uniqueness, is often a sign that can help solve a crime. When a crime lacks distinguishing features and appears common or ordinary, it becomes more challenging to identify the perpetrator. By contrast, cases that possess distinctive elements or are unusual in nature provide more clues and make it easier to establish responsibility. The quote emphasizes the importance of recognizing the exceptional aspects of a crime in order to successfully investigate and solve it.
