The final cache location is also
nearby, has a cafe, and is full of historical interest.
Parking is not easy in Kew but during daylight hours the Retail Park in Kew off the A205 South Circular is as good a place as any, if you cant find a spot around the green.
The first two clues take place at N 51 29.X and W 0 17.Y where X is less than 50 and Y is just less than 200. The only other clues I will give you are the pictures below.
The cache is at N 51 A.C , W 0 B.C
To find A:
find the differences in
their dates of birth
and add it to the differences
in their dates of death,
then double the result
To find B:
work out the difference
in their ages when
they both died and add
it to three times the difference
in their dates of birth
C = D *
E
To find D:
take the longer lived
person's year of birth
from the year
that the other stayed in Kew and reduce
by one
To find E:
take the difference in
their years of death
and add one
[ You'll know you have the
right C if you realise you may C one above you - not difficult in
Kew ]
The cache is a green biscuit tin
