In "On the Lisbon Disaster," a thrilling e-original story, New York Times bestselling espionage master Olen Steinhauer, author of The Tourist, introduces the enigmatic John Calhoun, an international security contractor who plays a prominent role in Steinhauer's novel The Cairo Affair.

Before his assignment to the CIA's Cairo office, John worked in Lisbon, Portugal, where he took part in an extraordinary rendition-the apprehension of a wanted individual for interrogation. But from the beginning of the operation nothing goes as planned, and for John, it soon becomes much more than a career-defining moment; how he handles this crisis will define who he is as a person.
