Dirk Gently

This involves running up large expense accounts and then claiming that every item (such as needing to go to a tropical beach in the Bahamas for three weeks) was, as a consequence of this "fundamental interconnectedness", actually a vital part of the investigation.

To prove this, Dirk cites as an example an incident where a young girl is somehow reciting the stock market prices exactly as they change but twenty-four hours earlier.

Dirk goes on to solve a highly elaborate time travel murder mystery, and accidentally answers the age-old question of exactly who interrupted Samuel Taylor Coleridge while he was writing the poem Kubla Khan.

Along the way Dirk stumbles onto a highly improbable horse in a bathroom, discovers who really composed all of Bach's music, and fails to find Schrödinger's elusive cat.
