"The woman who is now known as the mystery writer Anne Perry was born Juliet Hulme. At age 15, she and her schoolfriend Pauline Parker murdered Parker's mother Honora in a park in Christchurch, New Zealand, back in 1954.

Their story was the basis of the film Heavenly Creatures, starring Kate Winslet in her breakout role as Juliet, and Melanie Lynskey as Pauline.

You know how you read these mystery books for fun? The literary equivalent of a nice cup of hot cocoa? That's how I read Anne Perry, and to find out she actually murdered someone as a teenager was absolutely shocking. –rhdtmp0705
