...wali now looked at neval  in several different  ways  , he was worried  what  if that boy was armed with a hidden weapon  because such  gangsters and members of criminal groups  always carried  guns ready to kill  but there was something unusual in the boy s tone  that  surprised  wali  and asked him  if what was said about him was true that he   belonged to the rainbow gang

Neval shrugged  he was and also wasn't 

What exactly does it mean 

Neval  simply  leaned forward two years ago  his  step  brother was shot dead by one of the rainbow  , the argument started  over  a girl,  the step brother was elder to him he lived here only in  Miami  and  was buried here , in those days  neval lived with his mama 8n Jamaica  in Port  Antonio  just one hundred  kilometers away from Kingston 

Wali nodded  , he had spent some  time  in Jamaica with his wife  , he was  acquainted with  those  areas, , neval sipped his beer, when his mama was informed of Malcolm  s death she became very upset  that he was step brother to him but  a loved  family member,  he wanted to find out who killed him, a detective  was known to him and his family,  this known detective one day approached  neval and asked if he wanted to  avenge  Malcolm  s death
