It was buried deep, deep in the Arts section of Tuesday's NYT, but nonetheless, sitting in an airport food court, I found it:
‘Hitchhiker’s Guide’ Sequel Lands in Britain
Apparently it is not standard practice for British men and women to gather dressed in bathrobes and toting towels. When hundreds of fans thus clad assembled in London on Sunday, it was to celebrate the 30th anniversary of “The Hitchhiker’s Guide to the Galaxy,” the comedic science-fiction franchise created by Douglas Adams, and the publication of a new book in the series, The Guardian reported. At Hitchcon 09, held at the Royal Festival Hall in London, fans assembled (many of them dressed in the shabby costume of the series’s hapless hero, Arthur Dent) to pay tribute to Mr. Adams, who died in 2001. He was the author of the original “Hitchhiker’s Guide” radio plays and the five-book sequence they spawned.
And most importantly:
The convention also served as a kickoff for “And Another Thing...,” a new novel by the “Artemis Fowl” author Eoin Colfer that is cheekily being billed as the sixth entry in the “Hitchhiker’s Guide” trilogy. The American edition of “And Another Thing...” was released by Hyperion on Monday.
