Time travel, deep-sea diving and the quest for the holy grail are improbable ingredients of this delightfully surreal comedy.

Paul is a young physicist and keen swimmer, unable to get over his ex and frustrated by his lowly research job. He meets an older woman novelist, Molly, and finds himself becoming part of something called The Story. Is it a game, a secret society, an elaborate hoax?

Paul's search for an answer takes him to high-class casinos, London doss-houses and several hundred feet underwater. Fiendishly clever and charmingly silly, this is an intellectual farce in the spirit of Flann O'Brien or Raymond Queneau.
