A swimming trial is sabotaged, a betting ring is busted, and pint-sized private eye Fletcher Moon is forced to conquer his fear of water.

When someone tries to sabotage St Jerome's star swimmer, Harriet 'The Fish' Thompson's, training programme by putting purple dye in the school swimming pool, private detective Fletcher Moon is determined to find the culprit. His fear of water, however, threatens to jeopardise this aqua-based investigation.

Much to ace reporter Mia's amusement and Moon's embarrassment, it looks like he may fail to conquer his fear. Meanwhile, headmistress Quinn accuses Harriet's fellow swimmer, Shell, of the crime, and Moon's partner Red is also implicated. Can Moon correct this injustice? And why are The Pinks so keen that the swimming trial be cancelled? Show less
