Were literary detectives only effective against crimes of violence, or would they have been successful against white collar crimes?

Take any of these:

Hercule Poirot
Sherlock Holmes
Hardy Boys
Nancy Drew
Miss Marple
Adam Dalgliesh
Dirk Gently
Sam Spade
Inspector Morse
Perry Mason
and so on..

These detectives were all excellent at solving crimes of violence (murder, theft, kidnapping, etc.).

Would any of them had the skills to solve white collar crimes, such as Bernie Madoff, Kenneth Law, Jeffrey Skilling, Jeffrey Epstein, and so on?
