description: A Fatal Vacation
  
  Amy Kellogg and Wilma Wyatt appeared simply to be two bored, wealthy American ladies on holiday in Mexico City. But when Wilma suddenly; inexplicably jumped to her death from her hotel window, the carefree vacation turned into tragedy.
  
  Then Amy mysteriously vanished, leaving behind her personal fortune--and her strong willed husband, Rupert and her overly suspicious brother Gill. Each dependent on her wealthy, each distrusting of the other. Under a cloud of suspicion the two men were relentlessly propelled toward the secrets behind Wilma's death and Amy's disappearance--a search that could give each man a new life...or a sudden death!
