Jeffrey Siger is an American living on the Aegean Greek island of Mykonos. A former Wall Street lawyer, he gave up his career as a name partner in his own New York City law firm to write the international bestselling, award-recognized Chief Inspector Andreas Kaldis series of mystery thrillers telling more than just a fast-paced story.

The New York Times described his novels as "thoughtful police procedurals set in picturesque but not untroubled Greek locales" and named him as Greece's thriller novelist of record. Athens Insider Magazine hails him as "a literary star," the Greek government selected him as the only American author writing novels serving as a guide to Greece, and Reader's Digest calls him "one of our new favorite authors."

Jeffrey Siger has also served as Chair of the National Board of Bouchercon, America's largest mystery convention, and as Adjunct Professor of English at Washington & Jefferson College, teaching mystery writing.
