The Last Detective — Leslie Thomas

Dangerous Davies earned his nickname the same way that fat men nicknamed Tiny earn theirs. He is known as the last detective not because there are no others like him, but because he is, in nearly every instance, the last boy picked for the team. With little actual work to occupy him, Dange has plenty of time to pick through the cases that everybody else has forgotten. When he stumbles across a piece of ancient history, it looks like the perfect way to keep him out of the real coppers' way.
