On June 14, 2006, Graham Allaway received a shocking call in his office. His boss, Samuel "Skip" Ackerman, had just walked off the stage at an investors' conference in New York City and suffered an apparent heart attack. Within hours, Ackerman, the energetic chief executive officer of Panacos Pharmaceuticals, would be dead. Allaway, the company's chief operating officer, found himself staring down a crisis.
