Detective books provide detailed information on lock picking,home intrusion
The indian mainstream media does not carry the news of how the local intelligence and security agencies are entering the homes of private citizens illegally , and stealing whatever they wish, causing great inconvenience and financial losses
However most detective books like Private Delhi have very detailed information of how detectives and others are picking the locks of whichever house they wish.
The domain investor, engineer has been a victim of home intrusion for a decade or more.
The problem is particularly severe in panaji, goa,
Changing the locks repeatedly has also not helped in any way because the trespassers have a lock picking kit, allowing them to enter whichever house they wish.
So other than the story or plot, the books are a good source of information on trespassing, intruding in homes.
