After a decomposed body is discovered in an abandoned military tunnel, Inspector Aurelio Zen travels north to the Italian Alps to investigate. At first glance, the death appears to have been an accident. But when Zen takes a closer look, a mysterious tattoo begins to tell a much more sinister tale, especially after the body is snatched from the morgue. As Zen races to discover the inner workings of a clandestine military organization named Medusa, he is reminded of just how lethal Italian history can be.

Medusa takes us on an exploration of the dark history of post-war Italy and a modern-day sightseeing tour of what Zen calls Italia Lite. In the urbane and pragmatic Zen, world-class mystery novelist Michael Dibdin has given us a detective unlike any other. And in this latest installment of this critically acclaimed series, we are treated to a mystery that drips with intrigue and a thriller so satisfying the pages cannot be turned fast enough.
