The Fourth Secret

In the latest mystery featuring Inspector Montalbano, a deadly accident at a building site prompts a search with shocking revelations
Yesterday morning around seven thirty, an Albanian construction worker, age thirty-eight, Pashko Puka, a legal resident with a work permit, hired by the Santa Maria construction company owned by Alfredo Corso, fell from a scaffold that had been erected during the construction of an apartment building in Tonnarello, between Vigata and Montelusa. His coworkers, who immediately rushed to his aid, unfortunately discovered he had died.
There have been six events euphemistically called "tragedies in the workplace" in the past month. Six deaths caused by an inexplicable disregard for safety regulations. When the local magistrate opens an investigation, Inspector Montalbano is on the case. But Montalbano soon discovers that these seemingly unrelated incidents are only part of a larger network of crimes.
This intricate novella is a testament to Andrea Camilleri's talent for building engaging plots that continue to charm readers by the thousands.
