Vienna, 1903. In St. Florian's military school, a rambling edifice set high in the hills of the City's famous woods, a young cadet is found dead - his body lacerated with razor wounds. Once again, Inspector Oskar Rheinhardt calls on his friend - and disciple of Freud - Doctor Max Liebermann, to help him with the investigation.
In the closed society of the school, power is everything - and suspicion falls on an elite group of cadets, with a penchant for sadism and dangerous games. When it is discovered that the dead boy was a frequent guest of the deputy headmaster's attractive young wife - other motives for murder suggest themselves.
A tangled web of relationships is uncovered, at the heart of which are St. Florian's dark secrets, which Liebermann, using new psychoanalytic tools such as dream interpretation and the ink-blot test, begins to probe. At the same time, a shocking revelation makes it impossible for Liebermann to pursue the object of his affections, the Englishwoman Miss Lydgate, and he finds himself romantically involved with the passionate and elemental Trezska Novak - a mysterious Hungarian concert violinist, gifted with uncannily accurate intuitions. Again, all is not what it seems, and Liebermann is drawn into the perilous world of espionage - and must make choices, the outcome of which will threaten the entire stability of the Habsburg Empire.
Fatal Lies - volume three of the Liebermann Papers - is abut sex, the will to power, and deception.
