The villainous Janet Conway
Janet Conway (Ann Turnbull) is a villainess from "Personal Effects," episode 4.03 of Warehouse 13 (airdate August 6, 2012). She is the wife of Hank Conway, as well as the owner of golf clubs that belonged to famed golfer Bobby Jones.
Hank bought the clubs at a pawn shop and presented them to Janet as a joke, doing so knowing that she hated golf and also due to his desire to continue playing the game with his friends just to get out of the house. However, the clubs were an artifact, as the holder of the clubs became angry and violent over the tiniest things, due to Bobby Jones' infamous temper. The clubs affected Janet, and she was had attacked Hank with a nine iron from the set.
Artie Nielsen and Leena were searching for the clubs, as they were one of many artifacts distributed by Walter Sykes (Season 3's big bad). After finding Hank, Janet was found attacking Hank's friends with the clubs, while also angrily ranting over Hank shirking on the housework just so he can. Artie distracted the villainess by telling her that Hank was in the vicinity, which allowed him to take the club from her possession, bringing Janet back to normal before the artifact was neutralized.
