Let's break down the possible parts:
* Dragnet: This refers to a classic American police procedural television series, which ran from 1951 to 1959, with revivals in the 1960s and 1970s.
* Solar Pons: This is a fictional character, a detective in the Sherlock Holmes mold, created by author August Derleth.
* et al.: This Latin phrase means "and others," suggesting there might be additional elements.
It's possible you're referring to:
* A specific episode of Dragnet that featured a case involving a character like Solar Pons. However, this is unlikely as Dragnet was known for its realistic portrayal of crime.
* A fan-made project combining elements of Dragnet and Solar Pons. This could be a fanfiction, a comic book, or a role-playing game.
