The Third Circle

Leona Hewitt, disguised in men's formal evening clothes, has secretly
made her way into Lord Delbridge's private museum to find a relic stolen
from her family. But someone else is in the dimly lit gallery on the
same errand: a tall, black-cloaked man whose very voice is enough to put
her in a trance. Thaddeus Ware, a mesmerist with psychic gifts, is
accustomed to fearful reactions from others - women in particular. But
Leona shows no trace of hysteria in his presence. A gifted crystal
worker, she exerts a rather hypnotic power over the hypnotist himself.
And she is determined to keep the crystal they recovered. Thaddeus, on
assignment for the Arcane Society, knows the menace Leona is courting by
absconding with the crystal. A source of remarkable energy, it holds
the potential for great destruction. Lord Delbridge has already killed
to acquire it, for it is his key to membership in the elite, shadowy
group known as the Third Circle. And, with the help of a ruthless hunter
of preternatural skill, dubbed the Midnight Monster by the press,
Delbridge intends to find her. With the stolen crystal in their
possession, the danger is only beginning...
