Rahasyer Sandhane by Rajesh Basu [Hardcover]

Dutira was arranging an excursion with her school friends in Karshiang. Kabul is also going with another job. At that time, by chance, they came across a photocopy of a strange symbolic map. It mentions various places in Nepal, Bhutan, China, Malaysia, including the northeastern part of India? Just a riddle or some deep secret? Although they did not give much importance, they got involved in many more terrible cases when they reached Karshiang. There is a blood-sucking creature flying in the darkness of the night. Eyes are catching. Why Mithilal is hiding the little boy? What exactly did the man with the ponytail mean by death's 'pan, pan'? Panther? What is the professor researching on palai or rare species of animals?

A dense novel written in a web of many mysteries.
