"Edison Bixby is wealthy, handsome, and, due to a traumatic brain injury, impulsively rude. He's also a brilliant insurance investigator who solves baffling crimes by figuring out how the design of the man-made world around us makes them possible. Enter Wally Nash: a struggling actor hired to keep Bixby from offending everyone he meets. Their first case together looks like a simple accident. Caroline Crowley took a nasty fall down a staircase at a shopping mall in front of dozens of witnesses. Video clearly shows the deadly misstep. But Bixby is certain she was murdered by design, subtly manipulated into causing her own demise. The mall itself made the crime intentional, if not inevitable. Now Bixby must prove his outrageous theory before a very cunning killer gets others on his hit list to murder themselves, too." --
