The plot concerns an ingenious method for accumulating gold from the sea, and an even more ingenious method for encoding that secret. Needless to say, nefarious forces want to get their hands on it, and Daisy, and her little brother, Co, get entangled into proceedings, determined to make sure that things turn out right.
The story was written by Trevor, an architect and founder of the Museum of Modern Art in Oxford. Eileen is a children's illustrator; she pencilled the artwork and then Trevor would make a clear-line tracing - an interesting collaboration!
The artwork is very much in the school of Hergé and has a lovely kinetic quality to it - the detail is absorbing from first page to last. And the story keeps you going, with equal measures of humour (whether puns or physical comedy - plenty of both) and drama, excitement and suspense.
