from previous

....she  had seen nothing,  no other car  nor anyone else,  was the murderer  present  , hidden somewhere and from where watching her,  did he know it she had  found the necklace  , a horrible idea cropped up in head  , if she had  spoken  to the murderer  unknowingly,  she had noticed that gruesome shine in the eyes of Charles,  what was the meaning of it,  , he was at home,  yes but since when,  he could easily have come back home driving his car  while she was going on her bike,  she must  call up the press though she had not witnessed anything,   fingerprints of Laila,  herself and of the third person must be present on the broken necklace,  she trembled,  if the murderer was  watching  her he knows it she has the necklace,  her door bell rang at that point,  she  tried to take a peek outside through the curtains,  all right  she  embraced herself if there is Charles she is calling the police,  if it's not him she is safe,  no need to worry,  only he knows she has the necklace,  , with the help of a tissue paper she picked the necklace up and  placed it in an upper shelf  of the dining room and returned to the sitting room,  she picked up her cell phone before going to the door,  she felt secure,  at least that's what she thought she opened the door to Dorothy 

Amanda  did you hear the news  asked Dorothy looking at her 

Come in, 

Dorothy followed her inside to reach the  kitchen to help herself to a soft drink  to come back to make herself comfortable in the sitting room sofa
