Murder in the lab! The famous forensic scientist Dr. Ramachandran is stone-cold dead, and Ruby RoseAEs father is the prime suspect. ItAEs one more reason for Ruby to hate the Gardens, the funky urban neighborhood to which she has been transplanted. Wise but shy, artistic but an outsider, Ruby must marshal everything and everyone she can to help solve the mystery and prove her father didnAEt poison his boss. Everyone? The list isnAEt too long: thereAEs T. Rex, RubyAEs big, goofy but goodhearted friend; maybe those other two weird kids from class; and that mysterious old lady in the apartment upstairs, who seems to know a lot about chemistry . . . which could come in very handy.
