The Charlemagne Murders

Six famous (or infamous, if you prefer) World War Two generals have been murdered in six different countries leading to separate quiet but intense investigations. INTERPOL is finally involved because the police in each country come to realize that there has to be a connection, but no one knows what that connection is. Once links seem plausible, the Mossad joins the international police investigation and search; and the greatest manhunt in history is launched spreading over four continents and delving into secrets best left undisturbed.
