Only Connect #40 Mystery Cache

Number 40 of the Only Connect series of puzzle caches. The published coordinates are not those of the cache. Solve the puzzle to find them and they lead to a magnetic BYOP final. The cache itself can be found at an appropriate location.

The rest of the series can be found by clicking on this link to the Only Connect bookmark list.

To solve this one, you need to work out how the three images below are connected.

As I feel in a good mood, here are a couple of extra clues in picture form:

Once you have worked out how things connect, the following questions should be pretty straightforward:

A=the number of letters in the man of letters (3 words).

B=the number of letters in the (appropriately named) neighbourhood of his resting place.

C=the number of letters in the widely known name of his most famous creation.

D=the number of vowels in one of the titles his creation is also known as (for clarity it is the title with 17 letters).

E=the number of letters in the married name of his creation's wife (two words).

The cache can be found at : N55 01.Y W001 37.Z

Where Y = ((B + C) x D) + (A x E) and Z = ((A + C + D) x E) + B

You can validate your puzzle solution with certitude.
