Harvey

Mr. Harvey (unknown – 1789) was an English contract killer and bounty hunter working with Mr. Hook during the French Revolution. The pair were hired by the Carrolls in order to avenge their daughter, May, and to kill Frederick Weatherall, Élise de la Serre and her maid Hélène.

The two men traveled to Paris in 1789, and used the lootings that followed the Taken of the Bastille, to pose as commoners sleeping off their wine into the De la Serre estate after it had been sacked. Waiting there the return of Elise, the hitmen captured the young Templar when she came back to her house and prepared to torture and kill her as ordered by Mrs. Carroll.

However, Élise took advantage of a moment of distraction from Hook, who was body searching her while Harvey held her at gunpoint, to attack the man and thus prevent Harvey to instantly shoot her. During the brawl, Élise used a broken banister strut to deal a mortal blow into an eye of Harvey and succeded to recover her pistol while Hook was doing the same. Holding each other at gunpoint, Élise used the timely arrival of Bernard Ruddock to shot a distracted Hook into the mouth, instantly killing him.
