The Lover's Portrait: An Art Mystery by Jennifer S. Alderson
The story kept me engaged from the start; it deals with a fascinating time and an emotive subject. It's well written and has been well researched. I must admit it's a subject that fascinates and infuriates me equally. I can't understand how people can treat others so badly, and continue to do so over many years.
Great setting too. I've never visited Amsterdam before, but I think I'll add it to my 'to visit' list!
Zelda is a great lead character and I look forward to her future exploits.
