Come and meet author Penny Batchelor, who will be signing copies of her new thriller.

She knows all your darkest secrets . . . Now she's the woman next door.

It's been twenty-five years, but I'd know that laugh anywhere. I freeze. Don't let her in. Now she's standing in my kitchen, smiling and shaking my husband's hand with her perfectly manicured nails. Stacy. She's our new next-door neighbour. What is she doing here? What does she want this time? I worked so hard to put the past behind me, to build this life for myself.

Penny is the author of psychological thrillers – My Perfect Sister, Her New Best Friend and The Reunion Party published by Elma Books. Penny is a co-founder and judge of the ADCI Literary Prize for adult fiction by a disabled/ chronically ill novelist, is a Bookseller colmunist and speaks regularly at festivals.
