Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Matthew Van Helsing, the alleged descendant of the famed 19th century Dutch physician Abraham Van Helsing, owns an antique shop built over the site of Carfax Abbey in London in 2000. One night, with Van Helsing upstairs, his secretary, Solina, allows a group of thieves, led by her boyfriend, Marcus, into the shop. The thieves infiltrate the shop's underground high-security vault and find a sealed silver coffin protected by a deadly defense system. Based on the level of security surrounding the coffin, Solina and Marcus decide that the coffin's contents must be valuable, so they escape with it and flee to New Orleans. When Van Helsing discovers that the coffin has been stolen, he boards a plane to America, telling his apprentice, Simon Sheppard, to remain in London. Simon does not follow these instructions and follows his mentor.
Aboard the plane, one of the thieves manages to open the coffin, revealing the dormant body of Count Dracula. Dracula awakens and attacks the thieves, causing the plane to crash in the Louisiana swamps. Dracula survives the crash and travels to New Orleans, where college students Mary Heller and Lucy Westerman are living. Mary is estranged from her family and has recently been plagued by nightmares of a strange, terrifying man.
A:
What is the full name of the person that has an underground high-security vault?
