Fatal Remedies by Donna Leon

The provided text details a complex criminal investigation led by Commissario Brunetti following an act of vandalism where his wife, Paola, breaks a travel agency window. This initial incident, fueled by Paola's outrage over the agency's involvement in sex-tourism, unexpectedly spirals into a murder investigation when the agency's owner, Dottor Mitri, is found strangled. As Brunetti probes deeper, he uncovers a network of illegal pharmaceutical production and a cover-up orchestrated by Mitri's brother-in-law, Bonaventura, ultimately leading to the arrest of the hitman, Palmieri, and exposing the dark truths behind the seemingly legitimate business. The narrative explores themes of justice, personal conviction, and the moral compromises made in the face of widespread corruption, while also examining the strained relationship between Brunetti and Paola as they navigate the personal and professional fallout.
