Jay, Thanks! for the ref. And thanks for the link, polyglot2. I'd never heard of this new book, and I'll definitely buy a copy. This is great, especially if Prof. Berard will write more.

You probably mean the Conventiculum Latinum Lexingtoniense, which is the best known of these in the U.S.
http://mcl.as.uky.edu/conventus-latine-loquenti... , but Stephan Berard, the author of the book Jay mentioned, runs another such, which is well known:
http://www.latin.org/programs/septimana/ . There are several others around the U.S., in Europe, and even in the Far East. Here's a page w/ many of them listed:
http://www.circuluslatinusinterretialis.co.uk/h... . Most have already taken place this year, but there is always next year.
Another "modern" (100 years ago) mystery, translated into Latin; is the Mysterium arcae Boulé ; it is linked to from this page,
http://www.pantoia.de/Avellanus/InsulaThesaurar... , where other good translations by the same person, Arcadius Avellanus, are listed, with links--Treasure Island; a seafaring story about the Phoenicians (originally written in French); a collection of fairy tales, etc. All these books are available as publish-on-demand books from
amazon.com, too. And there is also this,
http://www.circulus.fr/opera/fabulae/dexter/dex... (which I have not read yet, but it looks good; the "folia" are composed in page order; those marked "liber" are arranged for printing, w/ pages out of order; or select "in computatro"; those listed to the right have facing French translations).
However, I'd say the S. Berard book would be the book to buy. Living authors should be encouraged!
