I was in-line skating in a square in the downtown part of a town that had hosted a major in-line skating exhibition. I was looking for a man whom I had had some occasional business dealings with, and who owed me something. I went into a jewelry store on the square to look at some gold jewelry out of general interest. Unexpectedly, it turned out the man I was looking for was inside. I went to the back of the store, where there was an employee and an old woman whom I did not know who seemed to be the owner of the store.
She was about 5'5", husky, plainly dressed, and had a thick coif of gray hair, about shoulder length. She seemed to know of my relationship with this man. She gave me a small booklet about 3 wide and 5 inches high with of about a dozen pages and a little packet of soil in it. I could not tell what was written in the booklet. She asked me to find out what was in the soil and where it came from, and then return to her with that information. I got the impression she wished me to contact her in person rather than using a phone.
How could I go about finding out about the soil inexpensively and discreetly. I did not want to invest much money in it. I don't know why she asked me, or why she doesn't do it herself.
