Lacey Maxwell

Lacey Maxwell is the main villainess from the third-ever episode of Psych, "Speak Now or Forever Hold Your Piece."

She was played by Christine Chatelain.

Lacey Maxwell is the sister of Dylan Maxwell, who is set to marry his fiancee, Bethany Coleman. She also serves as the wedding planner and the maid of honor. The triumvirate were met by Shawn Spencer regarding a valuable wedding ring (which belonged to Dylan and Lacey's grandmother) having gone missing, and while on the case, Shawn and Lacey develop a rapport and a date is set. However, Shawn (much to his dismay) figured out that Lacey was behind the theft of the ring.

Before the wedding, Dylan and Lacey's father--an Attorney General--presented the ring to Bethany. Lacey, who felt she was more deserving of the ring and was expecting to get it, hatched a plan to get the ring for herself, beginning with suggesting that it would be used during the wedding rehersal. After the rehearsal was done, the ring was set to be locked up again, but Lacey took that opportunity to steal it. However, she still had the ring in her possession while preparing the bouquets, so the villainess hid it inside one of them, with the plan to get it back later. This led to yet another snag in her plan:  the bouquets were locked up. Even worse for Lacey, Dietrich Mannheim caught her theft and threatened to report her to the police if he wasn't in on the action. During an argument in the kitchen, the evil Lacey killed Dietrich with a blow to the head with a fire extinguisher, and stuffed his body inside a dumbwaiter. After the murder, Lacey retrieved her bouquet, which had the ring.

Shawn outed Lacey during the wedding, with the villainess responding that she deserved it for putting in all of the work for the wedding. Lacey attempted to the escape, but she was later tripped up and eventually arrested.
