We saw the first 2 or 3 play adaptations ... but found them so disappointing (just like 2 hours of nonsense on ITV) that we vowed not to go again.
I think those applauding enthusiastically are doing so in blind faith!
I know the 'real' Guy Batchelor that appeared much later on in the Roy Grace series. It was supposed to be for one book only but he ended up being in a few and then ended up being a rather bad boy!
