Seth Klarman is a well known hedgefund manager behind the Baupost Group.
He wrote a book "Margin of Safety" that is long time out of print, and has quite a following, second hand books are sold for a small fortune on Amazon.
A discussion about the book can be found here, at an otherwise good forum about value investing.
The book is a bit outdated here and there, and mostly focussed on the US market, but other than that highely readable, and many topics and principles are timeless.
A download (from MediaFire) of Margin of Safety can be found here, at the second last comment.
