Yes, in the book it's Chummy who does the delivery on the ship - I can see why for tv they had to have two midwives there, so one could voice out loud what the problem was. But I thought they were far too relaxed about the fact that the girl was being used as a prostitute by the whole ship - if the ship had stayed rather than sailed off (as in the book), surely they would have felt obliged to report it to the police? Or at least expressed more horror about it?
I don't remember the DV story from the book but have obviously just forgotten it.
Am I right in thinking that at one point Chummy says "you are six fingers dilated"? (Which is impossible, of course.) Or did I mishear?
