Love letter to Pam

We received an anonymous Write_On submission that we just couldn't pass up sharing...

About 30 + years ago the mother of a school-friend died rather suddenly and, after clearing out her things, the daughter asked if I would like all her old dressmaking patterns and hoard of fabric. They were a well-to-do family and the mother was always effortlessly elegant and soignée and here were some beautiful items of both pattern and fabric from the 1950's when she had been a debutante.

Some years later when I went to use one of the patterns I found this letter inside the Lanvin Castillo design. 

I've no idea if anyone ever knew of the admirer/lover, somehow it's more poignant not knowing - a little touch of Madame Bovary or a sub-plot from a Trollope or Dickens novel.
