A Whiff of Sulfur
From Darkness to Light
Grayson seeks to determine whether Lady Jayne is a vampire hunter for the Order of the Dragon. Lucy mends Mina's broken heart with absinthe, romance and a whirlwind tour of Bohemian London. Grayson's machinations claim the life of Lord Laurent and earn him a powerful new enemy.
With Harker's help, Grayson begins to dismantle the Order of the Dragon from within by attacking its members one by one. He unmasks and threatens to exploit Lord Laurent's secret to his own advantage. This ultimately leads the Order to take drastic measures to reprimand members who break their rules. As a result of a chain of events resulting from Grayson's blackmail of Lord Laurent, he, in turn, earns a powerful enemy within the Order of the dragon - Lord Davenport. Renfield proves to be a sophisticated and skillful tactician in business matters on behalf of his employer. Grayson investigates Lady Jayne and finds brutal proof regarding her secret life within the Order - now he realizes he must change his tactics with her. Lucy tries to help Mina who is depressed over the current sad state of her relationship with Jonathan. Mina confides in Grayson about her troubles and Grayson offers Jonathan advice to help fix the situation. Jonathan and Mina reconcile and become engaged to be married - all according to Grayson's plan to continue to keep Mina close, but not too close.
