Prologue

In the Prologue we learn that there is a man that each year he receives "Mystifying flowers" that arrive by post on the first day of November. They are "always beautiful and for the most part rare flowers, always pressed, mounted on water-colour paper in a simple frame."

This year the man received a white flower. Unknown to him the flowers Latin name is Leptospermum Rubinette. A plant four inches high with small, heather-like foliage and a white flower with five petals about one inch across.  Also called known as Desert Snow.   The plant is native to Australia and to the aboriginal people it was regarded as sacred. The flower is difficult to grow in Sweden because it thrives in a dry climate and had to remain indoors half of the year.

We learn about the the policeman- a hardened veteran. Who has solved many cases in his life but the "Case on the Pressed Flowers" has been unsolved for years. This mystery only seems important now to the policeman and the eighty-two-year-old birthday boy .
