Alexandra is a licensed private investigator who specialises in domestic and matrimonial matters. With a French military background and is known to be down to earth, reliable and honest.

“My belief and commitment in supporting women in a traditionally male-dominated field led myself to establish one of the few all-female Detective agencies in this city.”

Some things in life can be incredibly challenging to deal with. There are issues that may just be out of your control, and regardless of how hard you try, you may not be able to find out what you need to know.
