Shirish plus the forest department had numbered the caves.

Shirish counted the quantity of shiny swiftlets coming into edible nest swiftlet the cave — the undertaking designed harder by some men and women traveling out and returning. This counting was a prelude. Shortly it absolutely was time to the grand finale — the objective for which I had arrive at the Andaman Islands all over again.
