Imagine whispering mummies, laughing shadows and invisible dogs … If you like the idea then the three investigators is for you: An American juvenile detective book series first published as “Alfred Hitchcock and the three investigators”. Three young boys investigating baffling phenomena by application of reason and logic. Created by Robert Arthur Jr in the early 1960s, the books were translated into many languages.
The series became particularly popular in Germany as ‘Die drei ???’ (the three question marks). So popular in fact, that from 1993 the German publisher Kosmos continued the series after the American version stopped. The German detectives even got their own audio drama, video games, graphic novels and theatrical plays.
As a huge fan of the series and data lover, I wanted to explore the audio drama in more detail while learning some new data science skills. Thanks to the fansite Rocky-Beach.com, I was able to collect data on each episode, and this is what I found.
