The London winter of 1893 turned out to be especially snowy. Chased by a storm, Gideon Bliss seeks refuge in a church. There, at the altar, barely conscious, lies a girl named Angie Tatton whispering something about Soul Snatchers. A flash of light, darkness—and Angie disappears. Snow swirls sweep up the dressmaker stepping over the window frame. Right on her skin, she embroidered a mysterious message—one that Scotland Yard and the brave journalist Octavia Hilling-ton, who has finally found a worthy occupation instead of useless society gossip, will have to decipher. Octavia and Gideon become woven into the same mystical web—both must unravel the mystery of the dressmaker’s death, find Angie, and scatter the darkness thickening over London.
