As usual, the film adaptation of the novel could have been great if they had stuck closer to the source material. Lucy Hale --- a Yank Detective with this team in London? Just would not happen and her character is a Male Brit in the novel. Killer is changed, ending is changed, but this version of Ragdoll can just be enjoyed on its' own as a decent mystery/thriller mini-series that chose to make major alteration from the far better novel.
