Gary Elringer, an eccentric young computer genius, had sunk most of his company's funds into the construction of Smart House—much to the dismay of stockholders, most of whom were family and friends. But, when Gary invited them all to a game of Assassin in the newly built house, he never dreamed he'd wind up dead for real. And, when one of the stockholders ends up dead, it's clear that nothing less than murder is afoot in Smart House. Constance Leidl and Charlie Meiklejohn's investigations soon show that all of Gary's guests had reasons for wanting him dead—but everyone's alibi is as well constructed as the house itself. Which leads to the next obvious question: Could the house be the killer? Just how smart is Smart House?
