A mystery story is only worthwhile when there is a layer of anxious feeling within that story. The story makes the reader think in advance. The author has tried to maintain that characteristic in every story of this book. Many also mix ghost stories, science fiction and detective stories with mystery stories. But none of the stories in this book have that mix. Although not a detective without a mystery, the mystery genre is unique. His secret is everywhere. Stories like Chanderkhani mystery, Garmandi treasure, Chandragiri horror, Kesinga's Banakuthi or Ratmohana are not only shrouded in mystery, but the inimitable role of nature is worth mentioning. After fifty ghost stories, the author's collection of twenty-five mystery stories is filled with mystery and mystery.
