Kinky Freidman is a little too Texas.
Dirk Gently, alas, will have no more adventures.
Thursday Next seems to fit the bill.
Heroine of The Eyre Affair, by Jasper Fforde, she lives in an alternate universe where the Crimean War is still going strong in 1985 and literary greats are worshipped like rock stars. Performances of Richard III generate the equivalent hooplah of a viewing of "The Rocky Horror Picture Show." Fun. Funny. Wacky. And there's time travel.
In summary, the wall between reality and fantasy has been breached. Jane Eyre has been kidnapped, and Thursday must restore her, as well as the novel's ending.
The official website, though confusing, makes good conceptual use of the technology to supplement this series of novels and flesh out Thursday's world.
