The Daemoniac (Gaslamp Gothic #1)

Sherlock Holmes meets The X-Files in this acclaimed paranormal mystery series from the author of the Fourth Element Trilogy

It's August 1888, just three weeks before Jack the Ripper will terrorize Whitechapel, and another murderer is stalking the streets of New York. His handiwork bears the hallmarks of a demonic possession—but amateur sleuth Harrison Fearing Pell is certain her quarry is a man of flesh and blood. And she hopes to make her reputation by solving the bizarre case before the man the press has dubbed Mr. Hyde strikes again.

From the squalor of the Five Points to the high-class gambling dens of the Tenderloin and the glittering mansions of Fifth Avenue, Harry follows the trail of a remorseless killer, uncovering a few embarrassing secrets of New York's richest High Society families along the way. Are the murders a case of black magic—or simple blackmail? And will the trail lead closer to home than she ever imagined?
