While on a seaside holiday with their friends George and Alexander, the Detective Society discover the body of famous swimmer Antonia Braithwaite - nicknamed The Pearl - on the beach.
Everyone presumes that she drowned accidentally - but how could such a famous swimmer have struggled to swim?
Even more mysteriously, three guests at the girls' hotel all wanted Antonia dead...
Can the Detective Society solve this mystery? Or will they sink under the pressure?
