"I think we should check the road behind this wall once as well. "

Sam said as she realized something. 

"So this is the road that leads to the house of the shopkeeper? " Miss Nair asked from the passenger seat as she looked at the front mirror to see Sam. 

"Yes. When Mon and I visited his house we saw it from the main road. This road is quite isolated here and is a short cut for his shop. Now that we discovered the proper location from where he entered,this looks obvious." Sam said. 

"This road is so isolated. Obviously it is perfectt for crimes. " Jake remarked. 

They were driving back to the same spot of the road where they performed the act on the opposite side of the compound. The car halted at that same location.Miss Nair hopped off the car and so did the others. She stood just in front of the wall with her arms crossed to her chest.
