Very far fetched, and I doubt that the female detective would have been allowed to act as prey to prove him guilty, and a very poor excuse to ask for a drink of water.
I wanted a proper ending, too, on way or the other. This certainly wasn't it and i will not be investing more time on a second series. Why would any of you folk do so if you were disappointed by the outcome of this one? There are times when i'm convinced some of you would watch paint dry:-/
unless she phoned the house and he fled knowing the game was up ? someone waiting to nab him.. ex copper/husband ?? will most likely forget it all by the next series !!
