Dear S,

I really liked your book format letter. It remined me of the puzzle letters I used to get from a pen pal who was doing his National Service in Germany many years ago. Some had to be read with the aid of a mirror and others were like jigsaws etc. Wish I had kept them now! He used to spend hours of his time off planning and writing them. I've never thought of those letters that I received well over 50 years ago unitl your letter arrived. Thanks.

Love M
