A Drop of Corruption - the gripping biopunk murder mystery sequel to The Tainted Cup

An impossible crime has occurred. A Treasury officer has disappeared into thin air - abducted from his quarters in a building whose entrances and exits are all sealed.

The brilliant and mercurial investigator, Ana Dolabra, and her assistant Dinios Kol have been called in to crack the case.

Before long, Ana discovers that they''re actually investigating a murder. Worse, the adversary seems to be able to pass through warded doors like a ghost, and can predict every one of Ana''s moves as though they can see the future.

Ana''s solved impossible cases before. But this time, with the stakes higher than ever and the investigators seemingly a step behind their adversary at every turn, has Ana finally met an enemy she can''t defeat?
