Jeffers Marston is the executor of E. Henry Merriweather's will.
After Merriweather passed away, Jeffers Marston approached the Ghostbusters on a Thursday evening. He revealed each Ghostbusters stood to inherit $1 million dollars if they could stay the night at Heck House from dusk to dawn without Proton Packs. Once they agreed, Marston drove them to Heck House and promptly left when he learned sun set two minutes ago. He later returned before sunrise and declared the Ghostbusters violated the terms of the agreement for leaving Heck House five minutes early.
