Starting this Saturday, an interactive mystery will unfold on the streets of Brooklyn Heights, open to intimate audiences of 10. Called ENIGMA, the show is as much a live performance with a roving cast of characters as it is a scavenger hunt for symbols through one of Brooklyn’s most storied neighborhoods. It even includes a stop for a complimentary drink, and we have discounted tickets for its first two weekends, June 29-30 and July 6-7. Enter the code BB at checkout to receive half off tickets (normally $60) for two or more fellow gumshoes.
