The clockwork scarab - 1 (First paperback edition.)

Reluctantly at first, Mina Holmes, the teenage niece of Sherlock Holmes, and Evaline Stoker, the teenage sister of Bram Stoker, combine their sleuthing and hand-to-hand combat talents to find out why society girls are turning up dead.

As the pair infiltrate opium dens, pubs, society balls and seedy criminal lairs, they discover that a secret society based on Egyptology is at the heart of the bad business.

As the teens get closer to the truth, they get closer to being counted among those killed.
