PN - 233/2 | The Thirteenth Gate (Gaslamp Gothic #2) by Kat Ross

Winter 1888. - At a private asylum in the English countryside, a man suspected of being Jack the Ripper kills an orderly and flees into the rain-soaked night. 
His distraught keepers summon the Lady Vivienne Cumberland—who's interviewed their patient and isn't sure he's a man at all. 
An enigmatic woman who guards her own secrets closely, Lady Vivienne knows a creature from the underworld when she sees one. And he’s the most dangerous she's ever encountered.

As Jack rampages through London, this time targeting rare book collectors, Lady Vivienne begins to suspect what he's looking for. And if he finds it, the doors to purgatory will be thrown wide open…

Across the Atlantic, an archaeologist is brutally murdered after a Christmas Eve gala at the American Museum of Natural History. Certain peculiar aspects of the crime attract the interest of the Society for Psychical Research and its newest investigator, Harrison Fearing Pell. Is Dr. Julius Sabelline's death related to his recent dig in Alexandria? Or is the motive something darker?
