During the 1958 World Expo, in Brussels, a part of the original manuscript of Mozart's Requiem Mass containing the last four words ever written by the great composer was stolen. It has never been recovered. In his suspense novel, Requiem for Riley, Roy Ziegler presents the gripping story about a powerful global investment broker, Heinrich Winterbottom, and his quest to find the precious fragment. The story involves international intrigue and a death-defying plot that unfolds in one of the most architecturally unique buildings in the world.
