Book excerpt: Five former Soviet hockey players who wound up in Detroit in the 1990s and helped to catapult a beleaguered hockey franchise to the top of the summit played a pivotal role in that city's celebrated comeback. They are The Russian Five, and while they changed their sport forever they also helped bridge rival cultures with their unique style of diplomacy. This is their remarkable story of espionage, defection, heartbreak and triumph - and remarkable courage after a fateful limo crash nearly killed one of them.
