The term 'BOOKIE CONCERN' is a crossword puzzle solution made up of four words: BET (3 letters), ODDS (4 letters), RAID (4 letters), and RAIDED (6 letters). Betting, or wagering money on the outcome of an event, is the main activity of a bookie concern. ODDS are the probability of an event occurring, and a bookie concern will set ODDS for different events. A RAID is when law enforcement officers enter a place to search for evidence of illegal activities. If a bookie concern is RAIDED, it means that law enforcement has searched the premises for evidence of illegal gambling.
