Geocache Description:

Visit the old parish church of St Peter in Holwell, Hertfordshire, but first you need to work out the puzzle or find the travel bug with the key information to locate Ground Zero. Park by the church and take a look around (not required to find the cache) then head out for a short walk (0.2 mile) to find the cache and a great view if you walk a little further for a sit down.

Update 10th Jan 2015: The letters have been changed but the puzzle remains the same.



St Peter's Church, Holwell

The Church
There has been a church on this site for over one thousand years. The Saxon King Edgar granted its charter in A.D. 968 and the current church of St Peter was built in 1877. It is thought that this is the fourth building on the same site. The church is unusual and, despite the rebuilding, retains some perpendicular features, a window depicting St Alban's cathedral and an interesting brass.

The Cache
The cache is NOT at the published coordinates. These take you to the front door of the church. However, it is hidden not far away, although NOT in the grounds of the building. To find the coordinates you will need to obtain the values of the letters A to K (excluding I) and plug them in to the following:

North 51 59.(J-G)(H+K)E West 000 18.(A-D)(F-G)A

Each letter uniquely represents a digit from 0 to 9. Do not multiply the results of the brackets.
e.g. (5-1)(8+0)6 resolves to 486

There are two ways to get these numbers. You can either figure out the values of the letters from the following multiplication equation or you can find the "Calling Puzzle Fans" travel bug (TB4Y9TE), which has the code attached to it.

K D H K F K A x 5 = A G D J E F D
