The second in the Enid Blyton Adventure series this time the story centres around a castle. The timeline is the following summer brother and sister Philip and Dinah, Jack and Lucy-Ann and parrot Kiki are now living at Spring Cottage by the sea. But this time they are joined by local wild girl Tassie and a fox cub called Button.

Someone who saw me reading this on the train said it was their favourite book of the series. And it is a cracking good story, lots of nice detail - "He crouched down like a toad against the earth." Last time Jack was searching for the Great Auk this time it's Eagles. A really good follow up to the first adventure with enough new elements to keep it interesting. Highly recommend.
