Dexter Morgan isnt exactly the kind of man youd bring home to your mum. At heart, hes the perfect gentleman: he has a shy girlfriend, and seems to lead a quiet, normal life bordering on the mundane. Despite the fact that he cant stand the sight of blood, he works as a blood-spatter analyst for the Miami police. But Dexter also has a secret hobby: he is an accomplished serial killer. So far, hes killed 36 people and has never been caught because he knows exactly how to hide the evidence. And while that may lead some people to assume hes not such a nice guy, he tempers his insatiable hunger for brutality by only killing the bad guys. However, Dexters well-organised life is suddenly disrupted when a second, much more visible serial killer appears in Miami. Intrigued that the other killer favours a style similar to his own, Dexter soon realises that the mysterious new arrival is not simply invading his turf but offering him a direct invitation to come out and play...
