This manor belonged to the head of the London vampire clan Alexei de Quincey in the Victorian Age, and it was located in Carleton Square, London.
History[]
Alexei de Quincey was the owner of this house. He used to give parties for his clan in which mundanes were murdered as a show, violating the Accords. He chose mundanes that nobody would miss (prostitutes, criminals, etc) and dumped their bodies in the River Thames when he was finished with them.
In 1878, during one of these parties, his victim was supposed to be Nate Gray but Tessa Gray, accompanied by Will Herondale gatecrashed the party. They got in by having Tessa Change into Camille Belcourt while Will posed as her subjugate, Archer.
The party was interrupted when the London Enclave swooped onto the premises and proceeded to kill all the vampires there for violating the Accords. However, Alexei De Quincey escaped and vanished away into the night.[1]
