My Lovely Wife

Dexter as written by Gillian Flynn - introducing the next generation of domestic thriller
Every marriage has secrets. Everyone has flaws. Your wife isn't perfect - you know that - but then again nor are you.
But now a serial killer is on the loose in your small town, preying on young women. Fear is driving your well-behaved young daughter off the rails, and you find yourself in bed late at night, looking at the woman who lies asleep beside you.
Because you thought you knew the worst about her. The truth is you know nothing at all.
