The Puzzlemaster has a job for you – can you recover a secret document from a rival organisation? We’ve tracked it down to a Submarine located just off the Cornish coast, arranged for it to have an accident and now it’s taking on water. The crew are gone, but we don’t have long before the water flooding in destroys the document.
Can you and your team break through their security and recover the document in time?
