Hidden

When Chief Inspector Andreas Kaldis's longtime assistant, Maggie, returns to her ancestral home on Ikaria for her 104-year-old grandmother's funeral, she quickly realizes not only was Yiayia likely murdered, but that a series of other long-lived Ikariots had recently died under the same suspicious circumstances. Back in Athens, Andreas and his chief detective Yianni pursue a smuggling and protection ring embedded in the Greek DEA, and its possible involvement in the assassination of an undercover cop.

But then Maggie and Yianni uncover a connection between their respective leads in the elder-killings on Ikaria and the DEA corruption case, and they realize that there are international intrigues far more dangerous at play than anyone had imagined.
