" Mam, there is a toll plaza after 5 Km, I mean 4 Km from them, so can I alert the toll plaza to take look through cars. We can get a picture" Sara asked seeing the map on her phone. 

" Alert them, but I don't think he will take the way!" Parinithi said turning her attention from her laptop to Sara. 

Sara took her mobile and got the toll plaza staff's number from the control room. 

She called. 

" I will speak!" Parinithi asked for the phone. 

" Yes, mam." She handed over. 

" Hello, Toll plaza NH56?" She asked on the phone. 

" Yes, you are?" 

" I am Parinithi I.P.S DSP, crime branch. I need a favor from you" She asked with a crisp voice. 

" Good evening, mam! Yes, please. How may I help you?" She asked in a polite tone.
