From a recent log: "I dragged my son out with me (stinky cheese, when we get his account set up)". I'd been contemplating a stinker of a puzzle for some time and that one odd remark geed me up and provided a theme. So my favourite stinky cheese* the cache became, and if you feel blue: (a) hard cheddar, and (b) you know who's responsible!
A: Dr Syntax
B: 1331
C: N56 27.633 W002 58.208
D: 19 Park Crescent, London W1B
The cache is at:
N 51 12.(A*B*B) + B*(D-C) - (C-B)*(C-B)
W 000 35.(A*D) + (B*C) + D - C
