"Hi Tony,

"I hope all is well! 

"Found your email online. May I know if you have an office to do a session? My mother recently passed and we need some answers. 

"Thank you very much!"

My reply:

Hello __________!

Yes, we can do that. I will take one or two Spirit Questors along with me. You should have a quiet venue for this.

Before anything else, though, think about the matter carefully. 

Sometimes questions are best left unanswered, because that is part of everyone's karma--the deceased's and the bereaved's.
