|Appears in||Criminal Case|
|First appeared||Case #54: The Poisoned Truth (s1)|
Rosie was a famous history novelist, sporting a white dress shirt, a black dress overshirt, dress pants and carrying a book or two with her during the time of her murder in The Poisoned Truth. She had auburn hair and green eyes, and she was also seen sporting a golden necklace, golden earrings, and a golden bracelet with blue beads on her right wrist.
Jones and the player confronted Rosie moments before she knew that she was going to die for incriminating a Crimson Order secret, so she wanted to give a lead that she found something dark at the Pilgrim Village in 1645. She wanted to talk to the team but as she tried to help the team out, she was shot to death by a poison dart to her neck. Rosie died at the team's arms, but not without giving out a lead as her dying words were, "White Acres".
Nathan explained to the team that the killer wanted Rosie to die instantly before she had a chance to spill secrets about the Crimson Order. Nathan continued by saying that the poison transferred from the poison dart to her heart, which caused Rosie's heart to stop beating, causing her to die in seconds, which meant that the poison was deduced to have been made using several plant compounds, which also meant that the killer knew botany, but also confirming the poison dart to be the murder weapon.
Killer and motives
Rosie was about to expose the Crimson Order as insidious manipulators and the secret society did not want that to happen. They gave Ashton the order to kill Rosie so he could join them. For Ashton, the Crimson Order was proud of the city his family founded, as well as him, so he used "Killer Cards" and his purple lens monocles to follow the execution order, and to do what the Crimson Order wanted, Ashton hand-made a poisonous blowdart (using natural poisons from rare plants) so that he can discreetly kill Rosie in spite of Jones and the player catching wind.
At court, without any remorse, Ashton once again claimed that he committed the murder for the eternal glory of Grimsborough, and determinedly said to Judge Hall that putting him inside prison would change nothing as he could still act as a Crimson brother, which were grounds for Ashton to receive a lifetime jail sentence for the murder of Rosie Gatewood. As Ashton was taken away, he wanted to notify the player that "their days are numbered" on behalf of the Crimson Order, but Jones furiously countered that the Crimson Order did not scare his partner at all and that it was them who should be afraid instead.
