The recent "Scuttlebutt" from Black Peter
(http://members.cox.net/sherlock1/2005.txt) notes that Julian Barnes'
new novel "Arthur and George" is to be published by Jonathan Cape in
July. The notice on Barnes' web-site
(http://www.julianbarnes.com/bib/arthur&george.html) gives a
description and links to several reviews.
This case still attracts interest, nearly 100 years later.
