Delores is the evil niece of Old Man Goodrich (renamed Councilman Goodrich in the remake), and is a member of the villainous Phantom Gang, who tied up Goodrich and attempted to steal his fortune. She introduces herself to the Stooges during their investigation, and makes an impression on Shemp, as he continuously shifted his camera to Delores, who was seated seductively on the table. Delores later takes Shemp with her to a separate room, with intent on poisoning him. The villainess drugs Shemp's drink, but Shemp catches on and switches the glasses. However, Delores catches this and tricks Shemp into thinking that she switched the glasses back, which causes another switch. Shemp ends up drinking the spiked glass and goes into convulsions, much to the delight of the evil Delores. Moe and Larry arrive in time to save Shemp, but at that moment, Delores escapes.
Both Who Done It? and For Crimin' Out Loud had the same ending, with Delores and the rest of the Phantom Gang defeated by the Stooges after they save Goodrich and a huge melee ensues.
- In Who Done It?, the home belonged to Goodrich and he was simply abducted by the group. In the remake, Goodrich described the house as Delores' country estate.
- Christine McIntyre's "appearance" as Delores in For Crimin' Out Loud was all stock material from Who Done It?, as her final official Stooges appearance came in 1955's Of Cash and Hash.
- Among Christine McIntyre's other Stooges appearances include villainous roles such as Lorna Doone in The Hot Scots and Mrs. Allen in Vagabond Loafers, among a few others.
- Who Done It? was originally planned as a Moe, Larry, and Curly short, set to be filmed after Half-Wits Holiday. After Curly suffered his severe stroke, director Edward Bernds rewrote the original short for comedians Gus Schilling and Richard Lane, and released it as Pardon My Terror. Christine McIntyre appeared in a protagonistic role in the 1946 short, which featured a different villainess.
