Litwin & Silverman have done it again! While "The Block" was terrific, I'm putting my money on this one. If you want to travel down the road less travelled, this is the book for you. Set aside some time to learn about the 'gambling trade', and meet the likes of 'Tongue and Baker'. So that's how they cover their bets-I'd hate to meet those guys in an alley, even in the daytime!
