'The eighteenth Monk novel is a brilliant Victorian police procedural in which well-realized characters and settings are fascinating in themselves. And, as in all her Monk novels, Perry exhumes and exhibits yet another of the Victorian era's social evils' -- Booklist 'Anne Perry's Victorian mysteries are marvels of plot construction... What makes the plot truly remarkable, however, is the way Perry uses it to dramatize not the petty street crimes commited byt the poor but the lucrative trade of merchants who deal in drugs and human flesh' -- New York Times
