Private detectives who spy on future children in-law a booming industry in India

A branch of the Indian private detective sector which investigates potential children-in-law ahead of the big day is seeing a boost in business, while traditional arranged marriages decline.

As younger generations increasingly opt for love matches over arranged marriages for some families, the first step is not to call a priest or party planner, but a sleuth with high-tech spying tools to investigate their future in-laws.

Hiring a detective for your child's spouse can cost up to $2000 depending on the extent of surveillance.
