Perfect (2007)

In a town where gossip thrives like the ivy that clings to its mansions, where mysteries lie behind manicured hedges and skeletons hide in every walk-in closet, four perfect-looking girls aren't nearly as perfect as they seem. Three years ago, Spencer, Aria, Emily, Hanna, and their best friend Alison were the girls at Rosewood Day School. They clicked through the halls in their Miu Miu flats, tanned in their matching Pucci bikinis, and laughed behind their freshly manicured fingernails. They were the girls everyone loved but secretly hated—especially Alison. So when Alison mysteriously vanished one night, Spencer, Aria, Emily, and Hanna's grief was tinged with...relief. And when Alison's body was later discovered in her own backyard, the girls were forced to unearth some ugly memories of their old friend, too. Could there be more to Alison's death than anyone realizes? Now someone named A, someone who seems to know everything, is pointing the finger at one of them for Ali's murder. As their secrets get darker and their scandals turn deadly, A is poised to ruin their perfect little lives forever.
