On a freezing Christmas Eve in 1879, a forensic psychic reader is summoned from her Baker Street lodgings to the scene of a questionable death. Alexandrina Victoria Pendlebury (named after her godmother, the current Queen of England) is adamant that the death in question is a magically compromised murder and not a suicide, as the police had assumed. Alex must put her personal loss aside to uncover the deeper issues at stake before more bodies turn up.

Turning to some choice allies - the handsome, prescient Lieutenant Brooks, the brilliant, enigmatic Lord Desmond, and her rapscallion cousin James - Alex will have to marshal all of her magical and mental acumen to save Queen and Country from a shadowy threat. Our singular heroine is caught up in this rousing gaslamp adventure of cloaked assassins, meddlesome family, and dark magic.
