The Expo Affair is a narrative memoir of international intrigue and romance that took place in the exotic setting of Expo ''70 in Osaka, Japan. As a host at the Ontario Pavilion, the author, Geza Tatrallyay, was approached by three Czechoslovak hostesses who wanted to defect to Canada. Notables such as former Prime Minister Trudeau, External Affairs Minister Mitchell Sharp and General George Kitching play a role, as do individuals who have since become prominent in Canada as businessmen, artists and ambassadors.
