Welcome to Cap'n Firebeard's School for Pirates - the fiercest, baddest school on all the Seven Seas. Step aboard me hearties, and learn how to become a real pirate. It's a new term at Captain Firebeard's School for Pirates, and Tommy, Jo, Milton and Spencer are back on board the Rusty Barnacle for another adventure. But something fishy is going on. Someone is stealing sweets from Liquorice Len's tuck shop. When Tommy and friends find themselves in the frame, it's time to solve the swashbuckling mystery and find the culprit. But no one expects it to be a real-life sea monster!
