There's something about Nathan Fillion that, male or female. you just can't say no to. That's why we're rather sad to wave goodbye to our favourite 21st Century crime-fighting novelist (Jessica Fletcher was some dame lads, you've got to give her props). Tonight sees the intrepid writer making an agonising decision about the cover of his new novel, while his lady life Beckett has her own rather important choices to make. Be prepared, we have a feeling it's going to be emotional.
