Recommended by Sub Dave, one of my seemingly many ex-submariner friends, I picked this book up in my never-ending search for good military books.  It does not disappoint. 

Blind Man's Bluff:  The Untold Story of American Submarine Espionage is a collection of some of the USNavy's most daring reconnaissance missions using specially modified submarines during the Cold War.  From the first Captain to follow a new Soviet missile sub for 47 days (!) to the tapping of undersea telephone cables under 400 feet of water, the tales are riveting and surprising.  There is a great deal of high-tech shenanigans here!

A large, but very enjoyable read, I consumed this one quickly.  Each episode is laid out well and neatly presented for a single sitting.  The stories selected read like character driven novels and string together to form a intriguing look at the hidden side of submarine warfare during the Cold War.  This has become a permanent part of my collection.
