Quinn was interrogated during the murder investigation of Stephen Xaint for being the wife of Cecil Ister, one of the main suspects in the case. Both her and Cecil said that Stephen had stalked Quinn as he liked her, suggesting that he was quite creepy. She was not of much help and wasn't a prime suspect either, so there was no shock when the team found out she was innocent. The true killer turned out to be Clèment Ouleaunge, friend of the Isters. Quinn did not meet the team again.
