There is an IRC channel where you can chat to like-minded Tom Holt fans and
alt.books.tom-holt regulars, the #holt channel on Espernet. Espernet
servers are listed at http://www.esper.net/, or you can connect to
irc.esper.net on port 5555 to be assigned to a random server.
For those new to IRC, http://www.irchelp.org/ can provide some helpful
information and hints, and also lists IRC clients for various platforms.
