All is not well in Dexterland. Ever since a certain incident involving a serial killer connected to Dexter Morgan, the
Ice Truck
Killer, there has been a shadow in Dexter's life, and sadly it is not the Dark Passenger. It is his arch-nemisis Sergeant Doakes, who has always seen something off in Dexter and now with recent tragic events to spur him on (read Darkly Dreaming Dexter to see what I mean), Doakes has been tailing Dexter like an unnatural bloodhound.
With his Dark Passenger asleep in the back seat, Dexter slips more and more into his disguise, a life with Rita, and it begins to look like there is no way out... until an opportunity to escape is provided by a homocidal maniac. At a crime scene, Dexter discovers what is left of a human being and it is not long before the department is told to back off from the case and Washington sends in the big guns, in the form of Kyle Chutsky, man of many talents and mysterious background.
But as the body count rises, and the search for the homocidal doctor hellbent on revenge escalates into a deadly game of cat and mouse, Dexter begins to solve his own puzzle, realising that Doakes with his military background, may just know more than he is letting on. And somewhere in that devilish, twisted brain of his, a solution is brewing that will dispose of both his problems at once; Doakes and this new enemy who just very well may be even more sadistic than Dexter himself, if such a thing were possible. One thing's for sure, with Dexter as protagonist once again, you just know the ending's going to be a killer.
