Days of Night — Jonathan Stone

When retired police detective Joe Heller is called in to investigate what might be Antarctica's first murder, he quickly discovers that winter at McMurdo Station comes with a unique set of challenges: darkness, isolation, and the eccentric behavior of the research facility's 157 inhabitants. But a difficult investigation turns much tougher when all communication with the outside world is suddenly cut off.

While Heller works diligently to reconstruct the scene of the crime, evidence mounts that a pathogenic event could be ravaging the rest of the planet. As night descends, fear mounts, and confusion reigns, the killer strikes again. If this is a global cataclysm, is someone now picking off the human race's few remaining survivors? Is this the end of the world -- or just the end of Joe Heller's?
