Publisher's Synopsis
It is the start of the Easter holidays and Joe is horrified when he learns that his parents are planning to take him to the wedding of some distant relatives he has never met before. Joe's pleas to be left behind fall on deaf ears until his larger-than-life Uncle Jack turns up unexpectedly.
The rest of the gang are in the beach hut, contemplating how they will spend the holidays when Joe arrives, full of excitement about his Uncle Jack. He announces that Jack has invited them all on his boat to come on the trip up the coast for a few days.
Along the way they see dolphins and seabirds, broads and marshes - and a mysterious figure, covered in mud and looking like a wild man.
Who is this wild man? And what is Jack really up to? It's up to the After-School Detective Club to find out...
