The Sea of Adventure
by Enid Blyton (Macmillan, 1948); audiobook read by Thomas Judd (Bolinda, 2021)
Blyton mixes the formula just right in this fourth adventure, adding a real sense of peril to the usual holiday atmosphere. The girls make genuine contributions. Huffin and Puffin, with only one syllable between them, enter the pantheon of great support characters!
