The Cuckoo's Calling

Saw the last episode tonight... a bit disappointed. (Relies on one of the devices I find least satisfactory in detective fiction, level with 'the narrator did it but isn't mentioning the fact'.)
And I really, really hope that Glamorous Female Assistant and Grumpy but Apparently Bedworthy Detective are not going to be pitchforked into an affair with each other in future instalments (but have little hope in that respect).

I never did read the book, although I've been meaning to for ages; maybe it's better. TV adaptations are rarely an improvement on the original, although Dickens tends to improve with focus and trimming :-p
