This was an unusual, but very enjoyable Thomas and Charlotte Pitt mystery!
When Thomas is unexpectedly obliged to follow a suspect to France, he doesn't even have time to notify Charlotte, but sends a message to Narraway advising him where Pitt and another officer are going.
Shortly after Pitt leaves, Narraway is shocked to be advised that some money he thought he had provided to a witness to allow him to leave the country after helping special branch with a case has been discovered back in Narraway's account. In addition to the apparent impropriety of the money, the witness, because he never received the money, was killed. Narraway is removed from his job and told he needs to resolve the matter with incontrovertable proof that someone else put the money into his account.
Narraway quickly realizes he's being set up, and that the only way to clear his name is to go to Dublin, where all the people involved in this now 20 years old case are located and figure out who framed him and why.
But before heading to Dublin, Narraway decides to advise Charlotte about Pitt's whereabouts so she doesn't worry. But when Charlotte sees him, she realizes something is terribly wrong and forces him to tell her what it is. Once she knows the details, Charlotte insists that she must accompany Narraway to Dublin as he won't be able to investigate on his own, since everyone there knows and hates him. Against his better judgement, but desperate for some help, Narraway agrees to let her go with him.
This was an interesting, and, as always with Anne Perry extremely well-written, dual story. Although the two parallel story-lines do connect eventually, it starts out feeling like the reader is getting two stories for the price of one, and both stories are full of the usual intrigue, clever mystery and action that Perry's books are known for.
I also really enjoyed seeing Charlotte get to investigate on her own, not only without Pitt, but in a foreign country where she is out of her element. I love the Charlotte character, and her spunk and intelligence and bravery was fully displayed in this book.
And of course, the formidable Lady Vespasia - who is without question one of THE most fabulous and delightful literary characters EVER! - makes an appearance and gets some excellent scenes.
All in all, yet another wonderful read in the Pitt series! Recommended for those who enjoy period mystery, and/or Britain-base victorian mysteries.
