Who did it and why?
Thanks,
Peter.
James Callum and his "girlfriend" Michelle were the culprits. As I guessed
early on, there was something very odd about Michelle - it turned out that
she and James's PA Michael were one and the same person: he/she was in the
process of undergoing a sex change.
I can't remember the exact motive but I think it was tied up with concealing
the sex change. Frost got Callum to confess to conspiring with Michelle who
actually did the deed and whom Callum conveniently killed when she tried to
attack Frost. Supposedly there were no witnesses to the conversation between
the two of them (Callum and Frost), but secretly Frost was recording the
conversation and planned to reveal it to the newspapers to blacken Callum's
name - that was all he could do since there was no evidence on which to
charge Callum, and the actual killer (Michelle) was dead.
I didn't see that one coming. Certainly it looked like the PA was involved,
and the "girlfriend" did seem odd. I'll have to watch it again when it gets
repeated.
Thanks again,
Peter.
