The conclusion to the Montford Heirs series. This is the story of Jack/John, the 3rd missing child of Lord and Lady Exmoor, who was sent by his mother, Simone, with his sisters 20 years prior. She sent them with a locket for each of her daughters and for her son, the family ring of the Earls of Exmoor which belongs to the children's father. Simone's plan is to bring the children to her trusted un-named friend so she can get them safely out of Paris in the middle of the Revolution.
In the first two books, the Grandmother is re-united with her granddaughters after finding out that they had not died in Paris. They are all still under the impression that the true heir, John, died of a fever. He is actually living under their noses as a highwayman whom we met in the first two books. Jack, has no idea that he is actually John.
This is a great ending to the series, everyone winds up where they should be and Jack is reunited with the love of his life, Nicola. And of course the bad guy gets his due.
