The Adventures of Tolkien and Lewis?

[davem]

Another novel with a Tolkien connection, Fire & Ice, is out next year - http://www.booktrade.info/index.php/showarticle/22243

FIRE AND ICE introduces Magnus Jonson, an Iceland-born Boston-raised homicide detective seconded to the Icelandic police force after an attempt on his life by a drugs cartel in Boston. Magnus immediately becomes involved in a murder investigation after the body of a university professor is found at a summer house by a lake outside Reykjavík. Magnus discovers that two obsessive LORD OF THE RINGS fans, an Englishman and an American, have been negotiating to buy a previously undiscovered ancient saga from the professor – allegedly the saga on which Tolkien's masterpiece was based. Such a saga would be priceless without the Tolkien connection. With it, and with the possibility of the fabled actual ring existing, men could be driven to murder.

Obsessive Lord of the Rings fans driven to murder? huh! I get enough of that at home....
