Julian Hanshaw won the 2008 Observer/Cape Graphic Short Story Prize with Sand Dunes and Sonic Booms, described by the Observer as a “haunting, evocative and beautifully drawn story”. It is set on the south coast, and at the Denge mirrors in particular.

We loved Hanshaw’s sense of time and place – an effect he achieved partly through a series of sepia frames illustrating the south coast. Hanshaw is an animator by training, and moved to Winchelsea, East Sussex from London three years ago. Since then he has become ‘mildly obsessed’ with the area, particularly the spectral and strange Dungeness. The idea for ‘Sand Dunes and Sonic Booms’ came after a visit to one of the south coast’s sound mirrors – primitive devices designed to detect and track military aircraft before the First World War (though the ones in Kent date from the 1930s).
