This volume includes three novels in their entirety: THE ASSASSINS OF ROME: Jonathan has disappeared on a secret quest to Rome. In attempting to locate him, his friends must enter Nero's Golden House, and find an assassin. THE DOLPHINS OF LAURENTUM: A sunken wreck full of treasure seems to be the answer to the four detectives' woes. But someone else seeks the bounty - someone with a sinister connection to Lupus's past. THE TWELVE TASKS OF FLAVIA GEMINA: In order to save her father from a terrible fate, Flavia must perform twelve tasks - just like the Greek hero Hercules.
