A Betrayal in Munich

Tom Collins is a private detective in Manchester. He doesn't drink, smoke, shoot people or bed Dangerous Dames. His hobbies are old cars and old movies; his caseload consists mainly of loose women, lying spouses, runaway children and lost dogs.
When Tom saves an elderly man from a mugging in a Manchester park he is made an astonishing proposition. The man's name is Daniel Freeman, descendant of Jews who fled Hitler's Germany before the Second World War. Daniel's grandfather gave his wife a set of jewellery for their wedding anniversary. This was stolen by the Nazis but one item, a diamond ring has appeared in a sales catalogue in Munich. The only problem is that this was in 1986. Daniel Freeman asks Tom to go to Munich to see if he can find any trace of the ring.
In Munich Tom meets a beautiful woman whose work is to try to trace artworks stolen by the Nazis during the war. Together they delve into a mystery which will take them back more than a hundred years: from war-time Munich, to a beautiful actress in pre-war Vienna and all the way back to the last Tsarina of Russia and the Russian revolution.
As Avea begins to discover more and more about the murky business of artworks looted by the Nazis Tom fears for her safety. He flies back to Munich to protect her but only succeeds in putting both of them in deadly danger. Up in the hills above the fairy castle of Neuschwanstein they will discover the truth about the theft of the jewellery but will it all be too late to save them from a betrayal in Munich?
