Eventually I have learned this book (Chronicle Books, ISBN: 0-87701-800-6) is regarded as "voices" among those who are deeply involved in the world of Atlantic Salmon Flies. Nowadays, it's the legend. If you want this book you have to look around your local used-book stores or online trades. (That's much easier in this era, as I got mine. You may even find new ones.) The inductee who-is-not-mentioned-at-this-point (as I don't want to trade his name) became my mentor. Also, though indirectly, I came to know the person who dressed the fly on the cover. Everything seemed intertwined through this book.
