....shehzad  himself opened the door on the musical bell,  his assistant  stood there at the door,  shehzad couldn't  control his annoyance,  what kept you away so long 

The vehicle  got a flat tire on the way 

The dead body is lying  by the swimming pool 

Where is the swimming pool 

To escape  answering too many questions shehzad asked him to follow him,  yawar and two photographers  followed shehzad through the three walled room , yawar pointed towards the dead body  so this is shumaila  khatoon 

No , shumaila is this  one  sitting in the sofa and alive 

Impossible,  she is breathing   and nit dead 

Shehzad  asked  yawar to be quiet and listen carefully,  this woman  is shumaila  well and alive  the body is of her secretary sonia  now  go closer to take a proper look at the  scene 

You mean   check out sand and water

Everything of course,  that is how investigation is done  to find out from where did the killer approach
