Tajne Musky's 2009 book Secret Flies of the Czech and Slovak Fly-Tyers is a must have for any fly tyer worth their salt. The book is chocked full of photos and recipes for a vast array of flies. Contributors are many, including Martin Droz, Milan Junis, Jiri Klima, Vladimir Sedivy and loads of others. The book is a great companion to Karel Krivanec's book Czech Nymph and Other Related Fly Fishing Methods. Musky's book also stirs the imagination to come up with new and daring fly patterns.
