The first novel in the Agency series, A Spy in the House, is a brilliant debut that wowed me with its honesty and originality. Where as many novels seem to focus either on one genre or the other, Lee shines in perfectly combining both a historical fiction novel with an amazing mystery novel.As a bookworm, I have read plenty of historical novel, and to be honest, the Victorian period is one of my favorites. So when I got my hands on A Spy in the House, I was very curious to see how Lee would present her Victorian society. It seemed like only after a few pages, I was in love with how Lee represented every detail. It is like the fair city of London had come to life. Lee left no detail untouched. From the confines of the social structure to even the smell of the city itself, all the details are beautifully described. This can be said for the characters as well. Mary is quite simply amazing. She is witty, clever, and downright hilarious at times. I loved following her on her antics... which were never in short supply. As for the other characters, like Mary, they were fabulous. They were varied and very detailed. By the end of the novel it felt like I had made a new set of friends.A Spy in the House completely took my by surprise. It is a novel that is very easy to follow and will keep you on the edge of your seat to figure out who the bad guy is. Just keep in mind that appearances can be deceiving and trust no one.
