Buddy,

1. If you are sure of her husband and as u told us tat she is ur 2nd cousin, then meet her husband and tell him that you have seen her with him in some place and tell ur relationship with her to him and casually ask for her details (like Workplace, her future plans) not more than tat. If he is not coming on track, heir a driver who is an expert in driving and try to find the place where she lives.

2. As u said she is ur cousin, call her parents back home and speak casually for first time and then second time take her contact details from them by which u can trace her easily.

3. If u can find her workplace then everything is very easy.

Happy Tracing and May God Help you to get your lost money

Regards,

Anwar
