Dine and Die on the Danube Express: a Gourmet Detective mystery by Peter King

In ten words or less: Famous actress goes missing but it's her understudy that's murdered.

Review: The Gourmet Detective takes a ride on the twenty-fifth anniversary journey of the legendary train, the Danube Express. The accommodations are sumptuous, and the scenery spectacular, as the train winds through Austria, Hungary, Yugoslavia, and Romania.
Magda Malescu, a celebrated actress and one of the passengers, is missing, and a European tabloid's headlines announce that she has been murdered. Malescu turns up unharmed, but her understudy is discovered dead in her compartment, apparently poisoned. Who wants to kill the understudy, or is it a case of mistaken identity?
The train's security personnel request assistance from the Gourmet Detective, who on occasion has helped Scotland Yard with a case.
Why bother? While questioning the other passengers, the Gourmet Detective partakes in lovingly described meals of epic proportions. It's a wonder all the passengers weren't indisposed with heartburn for the entire trip. This series has the same appeal as Margaret Truman's books--for readers who enjoy a travelogue along with their mystery.
