Bodie in 'Heat-Trace'

One for Pros fans only, I'm afraid!

I've had Helen Raven's "Heat Trace" on my mind, on and off, for the past couple of years. I loved it, but I was at a loss to explain her Bodie. Doyle was fine, I could track his slide into depression and planned suicide. Bodie was "more difficult".

Anyway, ( I think I might have finally cracked it )

Also, this should be considered a lay person's attempt at solving a puzzle, not a professional opinion. Feel free to disagree with me!*
