Max is distraught when he receives a letter from the school telling him he has to go on a weekend of cycling and camping for the Duke of Wellington awards scheme. But things vastly improve when his friends agree to come with him.

It isn't long before they find adventure – or adventure finds them... They make a friend called Byron and set up camp in a forest near to his home. But that night they wake to see strange lights and a fierce wind blowing through the trees. Moments later Byron arrives, running and screaming that 'they' are after him. When the gang follow him, they find his rucksack but no sign of the boy. It looks like Byron has been abducted by a UFO! But surely that's not possible... is it?

Things in Southwold get off to a bad start! Max has to do extra lessons while Charlie has been roped into helping with the decorating. Meanwhile Lucy loses an important race to a new girl in her school, Miranda Fitchwitherington, who seems to enjoy being as mean as possible to Lucy and the rest of the gang.

And there is more bad news – when the gang meet Captain Tom, walking his own dog, Pugly, he tells them about an outbreak of pet thefts in the area. When they meet a lady looking for her lost dog, their worst fears are realised – there are dognappers on the loose in Southwold!


Summer is here and the After School Detective Club are looking forward to relaxing by the sea, but Charlie is horrified to learn that her mother has booked a week-long yoga retreat in Ireland. And what's more, Charlie has to go with her! Luckily, the rest of the Club agree to go too.

However, things get very strange, very quickly. Who is the mysterious figure they encounter one stormy night? Could it really be the legendary headless horseman said to bring bad luck to whoever sees him? And could this mystery be connected to the strange goings-on at the local stables? As always, it's up to the After School Detective Club to find the truth and save the day.


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...
