Double Dexter is the 6th in the popular Dexter series by Jeff Lindsay. When his latest playdate is witnessed by an unknown man, Dexter, our favourite serial killer with a conscience, suffers a great deal of anxiety, wondering if life as he knows and loves it is over. But it seems his witness chooses to follow in his footsteps, then blog about it, and Dexter decides he needs to remove this copycat from the land of the living, if only he can find him. But Dexter's understandable arrogance leads him to underestimate his quarry. While the first paragraphs are a bit repetitive, all that waxing lyrical about the moon, we can forgive Lindsay this when we know what is coming will be good. And it is. Dexter's inner monologue is always entertaining, even if he appears to be a self-pitying, inactive Dexter, performing at less than his usual Dexter standard. Not even motherhood has tempered the creative standard of insult and put-down that Dexter's ever-scowling sister, Deborah, manages to achieve. Lindsay reaches new heights with the scatter-brained Rita's hilarious disjointed dialogue, and Dexter's exchanges with Masuoka are always droll. Dexter's complete inability to read human emotions is highlighted and contrasts with his very human total lack of impartiality about his own offspring's abilities. Lindsay skilfully captures the feel of Miami, the humidity, the mindset, and gives us a good dose of irony with Dexter being suspected of a murder he didn't commit. As always, brilliant imagery and plentiful, imaginative D alliteration abound. The only problem with the Dexter series is waiting for the next one to be published.
