These precious gestures are as valuable as money. Of course, I was paid for my professional work, but this postcard is an additional gift that money can’t buy. This young woman from Ohio hired me to find her biological father—someone she had never heard of since shortly after her birth, 24 years ago, and had no memories of. Before yesterday, I finally found him in Iowa. I was able to talk to him and other family members, and I asked him if he would be willing to meet his daughter. They are all so excited planning to meet in person this coming Sunday. Her father and uncle also appreciated my work, but this card I just received from Rayna is truly special. It reads:
“Francisco,
Words cannot express my deep gratitude from your work. Your email brought tears to my eyes immediately. I have gone a long while wondering about my family and now because of you I know.
Throughout this process you have been forgiving, empathetic, and kind. I am so blessed to have found someone as wonderful and trusting as you.
Thank you with all of my heart,
Rayna”

I have already done several investigative jobs here, in the United States, for some Spanish colleagues and old friends, so I thought it would be a good idea to become a member of the Asociación Profesional de Detectives Privados de España [APDPE, Professional Association of Private Detectives of Spain], now as a “foreign” member (I had already worked as a Private Detective throughout Europe, licensed in Spain, my country of birth, from 1990 to 2013). These past weeks I have been doing all the paperwork and I have just been accepted as the only member of the APDPE in the United States.

Ya he hecho varios trabajos de investigación aquí, en Estados Unidos, para algunos colegas y viejos amigos españoles, así que he pensado que sería buena idea darme de alta como socio de la Asociación Profesional de Detectives Privados de España [APDPE], ahora como socio “extranjero” (ya había ejercido como Detective Privado por toda Europa, con licencia oficial en España, mi país de nacimiento, desde el año 1990 hasta el 2013). Estas pasadas semanas he estado haciendo todos los trámites y me acaban de aceptar como único miembro de la APDPE en Estados Unidos.
