Some people do seem to have an innate compass inside their head and others are totally clueless as to any sense of direction whatsoever. I feel from what I have read Jeremy was in the former category. Inspired by a good geography teacher at school he flourished in the subject. He often liked to explore new terrain and must have often surveyed the Blackwater Estuary environment. Just one of the many strange coincidences which contrived this tragedy.
Another favourite subject was maths,particularly arithmetic as he applied it to the takings at Osea Road in particular at board meetings and could see when the family finances were at their zenith. His third interest at school was chemistry,and again this manifested itself in an interest in poisons to slip into Nevill's gin and tonic,though realizing that cyanide might be traced he renounced this plan in favour of the shootings.
