- "Ever find a small bottle around here? Colchicum, the label says. You'll want to be careful with it. Sometimes it's a thin line between medicine and poison."
- — Catherine
Catherine is a serial killer. She married a man named James Dixon. At one point, she told Mrs Soames that James and she were siblings so she could rent them a room, she later killed both her husband and Mrs Soames using Colchicum.
Catherine later met a retired sea captain, named Mawer. After Mawer put her into his will, she killed him to receive the money.
Sometimes later, she started working as a nursemaid for Lord Cornelius, Lady Hathaway and their baby at their mansion. At some point, the baby became ill and died. Overwhelmed with grief, Lady Hathaway left Lord Cornelius. Catherine tended to him to the point Lord Cornelius put her on his will.
One day in 1862, a chambermaid named Olivia found a bottle of Colchicum inside a rag doll. Catherine killed Olivia and a footman was accused of the murder. But seven bodies were later exhumed and Catherine was arrested.
She was prosecuted by Mr. Clark and Mr. Beasely before the judge Mr. Justice Byles. Lord Cornelius spoke for her during her trial to no avail. Ultimately, she was publicly hanged at the Newgate Prison. Her spirit went back to haunt the mansion.
In 1912, Alistair Rhodes, now the owner of the mansion renamed Rhodes Manor, was preparing a party but was abducted by The Order whose members activated a Sentinel Artifact. During the trial, Catherine's spirit manifested and helped three guests and Alistair's butler to complete it.
After unlocking the Pack-a-Punch, if players are looking several times in a row into one of the seer stones they can witness a vision of a tortured Catherine with her neck partly severed.
