The Mystery Code

The Mystery Code starts with the disappearance of a school teacher in the quiet seaside village of Greystones, where nothing normally happens! While investigating their teacher's disappearance, Finn and his friends find a cryptic coded message that they use their computer coding skills to crack. The decoded message is a rhyme suggesting there may be treasure hidden along the coastline near where they live. They also find an emerald in one of the rockpools nearby! The children go searching for the treasure where they find their teacher who has had a kayaking accident crashing into the rocks while looking for the same treasure. This leads to a dramatic rescue of their teacher involving the coastguard. After seeing a glint from the sea and with extra information from their teacher, they return to search for the treasure...
