The ruby in the smoke by Philip Pullman, the first Sally Lockhart novel.
Soon after Sally Lockhart's father drowns at sea, she receives a strange anonymous letter. The dire warning it contains makes a man die of fear at her feet. Determined to discover the truth about her father's death, Sally is plunged into a terrifying mystery in the dark heart of Victorian London, at the centre of which lies a deadly jewel.
Pullmans Victorian London is a gritty city full of Opium dens and Villains, the attention to detail in the setting and characters creates a vivid reading experience. I loved the way all the main characters came together to form their own little family/gang.
The novel as a whole is very fast paced with some unexpected twists that thrill the reader but it also detracts a little from the novel as a whole, the ending felt rather rushed. Ultimately the speed of it means the plot in the final chapters suffered a little and lacked sophistication. Despite that I enjoyed it and will at some point read the rest of the series.
