A young music journalist, Imogen Charles, is asked by an opera star to help decipher some strange letters he has received... letters that he believes could well shed light on the unsolved murder of his partner.

Imogen and her good friend, Ned, follow the bizarre trail left by the letters across various concert halls and opera houses all over Europe, travelling to London, Paris and Provence in search of clues.

This is a tale of mystery heavily infused with music, romance, murder... and the heady scent of lavender.
