It is a dark and stormy night….as she walks carefully over the broken shells and rough sand she feels the foam curl around her ankles. Just a little more and she knows the shelf drops off into deeper water – water she can no longer stand up straight as she is now, waving her arms gently over the swells and skipping lightly. She ought not be out there at night. She knows that – yet there she is, taking chances with her very life. Musing about this something slinky slithers between her legs, knocking her off-balance.
