This category is for images of the hard-boiled detective, Problem Sleuth. Images related to the MSPA adventure should go in Category:Problem Sleuth (adventure) images.

If you're wondering why this category isn't disambiguated as well, consider how much more confusing (than it is already) it would be to have the parent of this category, Category:Problem Sleuth character images, contain this subcategory under the name "Category:Problem Sleuth (character) images".
