Often, they will have a sense of mystery and suspense. The plot will revolve around the abduction, the reasons behind it, and the efforts to rescue the kidnapped person.
I'm not entirely sure of a very popular kidnapping - based Urdu novel off the top of my head. But Urdu literature is vast. You could start by looking into the works of some renowned Urdu authors. Maybe check local libraries or Urdu bookstores where they might be able to guide you to novels that have elements of kidnapping in their plots. Sometimes, older Urdu novels that deal with social dramas might also have such elements.
One common theme is power dynamics. In many kidnapping - based novels, the kidnapper often has a sense of power over the victim, whether it's physical, psychological, or both. For example, in 'The Collector', the kidnapper feels a sense of ownership over the woman he has kidnapped.
Another is 'Room' by Emma Donoghue. It involves a mother and her son who are held captive in a small room. It shows their struggle for survival and the psychological impact of being kidnapped. It also explores the bond between the mother and the child in such a harrowing situation.
One well - known one is 'Kidnapped by the Pirate' where the female lead is kidnapped by a pirate but then a romantic relationship develops between them. It has elements of adventure along with the kidnapping - turned - romance plot.
By withholding information. In 'Room', we don't initially know all the details about the kidnapper or how the mother and son will escape. This lack of information keeps the reader on edge, constantly guessing and trying to piece things together. Also, the vulnerable state of the kidnapped characters, like the young woman in 'The Collector', makes the reader fear for their safety and creates a tense atmosphere.
