A simple offset multi-cache and the first of a series playing on the name of well-known films / Ludlum novels. You can find out more about the village of Bourn here.
The reason for the name of this cache should be obvious as you approach GZ. Within 2 metres of the co-ordinates you will find six digits. Use them to find the real location of the cache.
List the six digits in ascending order to give ABCDEF. The final may be found at N 52° 11.ABF W 000° 03.DEC.
The final hide is about a half-mile walk away, though can also be aproached from the road. The cache itself is a large camouflaged Lock'n'Lock box containing the usual goodies.
