Agência de investigações holísticas Dirk Gently (Dirk Gently #1)

Dirk Gently's unconventional methods and humorous outlook make him stand out. I'm curious what sparked Adams's idea for this eccentric detective.

The plot jumps around quite a bit, but it all somehow ties together. Did the randomness enhance the story or make it harder to follow for others?

The blend of scientific concepts with absurdity is so distinctive. I wonder if his scientific knowledge shaped the story’s worldview or humor style.
