from previous--

-in the  office  the  manager  was  shaking  with fear, he  had  found  a  pineapple  sized  and  shaped  hand  grenade  in his  office  drawer, the  man  who  was  there  found  out  it  was  a  plastic  toy  a  lookalike  of  a  bomb  but  was  lighter  than a  fire  cracker,  it  was  empty  inside,  no  explosive  material  , no  chemicals ,  assured  of  his  own brilliant  role  he  begins  investigating  the  case,  
-who  saw  the  bomb  first
-who  all followed  the  first  man in the  office
-who  was  under  doubt
-what  was  written in the  note  found  under  the  bomb
--it  was  addressed  to  the  manager  asking  for  a  loan of  five  lakhs  if  not  arranged  within a  certain  time  period  he  would  regret  the  consequences -still  not  revealing  that  the  bomb was  not  real  he  continued   to  question the  guard
