A young couple is found dead in their apartment, and double suicide seems to be the only interpretation - Alarm bells ring in the towering Manhattan offices of Eden Incorporated, the high-tech matchmaking company whose spectacular success and legendary secrecy have inspired awe around the world. The Thorpes, few people knew, were more than the quintessential happy couple - they were Eden´s first perfect match. Christopher Lash, a gifted former FBI forensic psychologist, receives an urgent plea from Eden to perform a quick - and quiet - investigation into the deaths. Lash´s investigation inadvertently dredges up the memories of a searing personal tragedy he has kept at bay for years, and his involvement becomes more personal and dangerous than he could have imagined. When a second Eden ´super-couple´ is found dead, Richard Silver, the company´s brilliant and reclusive founder, has no choice but to grant Lash unprecedented access to its most guarded secrets.
