Glittering Prospects

Set on Brighton Beach in 2098, an local metal detectorist records search-reports for the Council's new Portable Foundle Department; a new requirement since mysterious artefacts have started appearing on the beach...


Glittering Prospects is an immersive audio drama exploring humans' relationships with changing coastal environments through treasure hunting and local folklore.

Your piece doesn’t try to preach or present answers but helps the audience to pay attention. With audio, you have to work harder and use your imagination... that’s a muscle we need to keep working if we are to effect change.
Sarah Macbeth, visitor during the Dreamy Place Festival

Glittering Prospects is a deeply atmospheric 20-minute audio drama by sound designer Anna Bertmark that weaves together Brighton Beach’s hidden histories, environmental mysteries, and the stories of those who search its shores. Inspired by cinematic interview techniques, found audio recordings, and through interviews with metal detectorists, wildlife and folklore experts, the piece presents a compelling fictional documentary drawing from the world of treasure hunting and local coastal history and superstitions. Through the power of place-based storytelling, this immersive listening experience explores how lost artefacts buried beneath our feet reveal meaningful stories.


Glittering Prospects is performed by Rachel Capell, and also features the voices of Robert Champion, Susan Godliman and Paul Hayes. It was exhibited during the Dreamy Place Festival in Brighton 25-26th October, 2025, in a beach hut overlooking the sea. The production was supported using public funding by the National Lottery through Arts Council England.

The 'Making Of'
The inspiration for Glittering Prospects was the many layers past, present and future stories from the edges between land and sea...and of mysteries that lie beneath the water.
After a successful application for Arts Council Funding in early 2025, the challenge was to research, write, create and exhibit an audio drama.
For collecting inspiration for the story, I interviewed 13 metal detectorists, archeologists, local historians, artists, wildlife and folklore experts. I researched old Sussex dialect to add old words to the script to mess with time and space in a subtle way. The project included delivering a talk about metal detectoring and local finds at the West Pier Centre on August 28th for local history enthusiasts.
To create the sound-ingredients for the audio drama, I recorded footsteps, digging, gulls and waves on Brighton Beach over summer. Rachel Capell's wonderful performance was recorded far from the noisy beach; outdoors on Black Down heath on a sunny September afternoon.
For additional immersive flavour for the final piece's exhibit during the Dreamy Place Festival, I created a fictional 'Council Logo' to adorn my outfit, as well as making a biomaterial prop from a 3d printed mold of one of the strange finds from the story.
The ocean itself becomes a character; a visual and psychological backdrop for the audience’s imagination.
Having grown up overlooking the Öresund strait between Denmark and Sweden and now living near Brighton Beach since many years, I wanted to explore the beach as a canvas and stage for human imagination. Through highlighting local history, current environmental concerns, and our relationships with the coast, the aim of Glittering Prospects (a title in homage to Joan Allen's book) was to entertain while also to indirectly invite participants to reflect on these topics.

My background in film sound design would come in handy, but I had never written a script nor exhibited an immersive experience before. The creative core of the project lay in blending fiction with documentary-style storytelling, inspired by 'The Night Watchman' by Stephen Schwartz (1971). His ‘moments interview’ technique prompts interviewees to “talk in a sequence of pictures” to capture sensorially detailed statements that feels grounded in reality.
The story's theoretical influences also include: Le Guin's 'Carrier Bag Theory of Fiction' that sees a story as a container for objects and experiences, not just a linear plot; Haraway's concept of 'Natureculture'that shows how nature and culture is co-produced, not separate; Derrida's concept of 'Hauntology' which explains how past presences linger, shaping present perception; Anna Tsing's 'Art of Noticing' that urges us to pay attention to the small, often overlooked connections, and Michel Chion's 'The Gap’ in audiovisual media activates the audience’s imagination when visual information is deliberately withheld.

The story investigates a model of reality as a web of interconnected systemic actors as slow-moving life-forces that make up the world. The philosophical influences and governmental structures serve as invisible infrastructure supporting the story rather than direct audience encounters, focusing on what the audience will actually experience; the reports, a detectorist mystery, and the gradual revelation of the transformed future Brighton. Character reference material includes Digger Dawn on YouTube and Marge Gunderson in the film Fargo; happy-go-lucky, unfazed by the darkness surrounding them, through whose eyes and ears we are introduced to the world. Old Sussex dialect words are sprinkled throughout the script to add a surreal and familiar flavour to the story.

Drawing from interviews with local historians, wildlife specialists, folklorists, and metal‑detectorists, I wanted to weave together place‑based knowledge into a narrative that sits at the crossroads of environmental awareness, personal memories, and site‑specific artistic practice. Rather than direct messaging, it subtly encourages listeners to contemplate humanity’s imprint on the coast, the layered histories buried beneath the sand, and the sea’s enduring mysteries.

The environment and detector function as characters through narrative sound design, while the audio reports themselves are framed as future recovered and declassified material, introduced by a freedom of information request letter (pinned in the experience to the beach hut doors). By pairing the high‑quality binaural sound experience with tangible artefacts and the sea view, I aim to strike a balance between mystery and realism in a direct and intimate way. The ocean itself becomes a character as well as an effective visual and psychological backdrop for the audience’s imagination.
