In the book there is a criminal on the loose called Jack Door he is after Roberts mum Selena who abandoned Robert when he was very little. Jack is after Selena because she is Jacks daughter and she gave him up to the police 15 years ago. Lilly, Robert and Malkin’s job is to find Selena before Jack does so they travel on A airship from Brackenbridge (where Lilly lives) to London. Every time Jack goes somewhere he always leaves a playing card it is the Jack of diamonds it is always a clue. It is a book of mystery, sewage and clockwork.
I recommend it to people who love airships, adventure and shock.
I rate it 4 and a half out of 5 because I love the puzzles in the story and the place where it is set (in London) but it was really good. 🙂
