Dark Assassin by Anne Perry

Dark Assassin is book number 15 in the William and Hester Monk series. So, Here I go jumping into the middle of a series for my first time reading Perry. This was a great story though, and I could hardly put it down. Perry does tend to give endless details, but I was not put off by this.
William Monk, of the Thames River Police witnesses a young woman's fall (or was it a push) off a bridge into the icy waters of the Thames. It is ruled a suicide and the young woman is assigned the grave of a suicide. A humiliating end. But Monk is unsure of what he'd actually seen and his investigations lead him into the dark and forbidding underworld of the sewers and tunnels of London during the time when they were being rebuilt and redone. We meet Toshers and Navvies, and lumpers. Indigent and homeless children as well as the very high class of London Society. It is a very Dickensonian view of the Victorian era-London in the late 1850's. The tale is well told and there is plenty of suspense and a nice twist at the end. Perry has several series of books and if you can start at the beginning of one of them, it is probably the best choice. Try the William Monk series. I know you'll enjoy.
