After failing to wow their idol Felicia Taylor at a book signing, their disappointment is soon forgotten when they find themselves in an interrogation room being informed that they are two of the last people to have seen a recent murder victim.

Tensions finally come to a head at the Birmingham Convention Centre's Murder Con, a dramatic showdown that puts Kathy and Stella's friendship to the absolute test.

[4] Kathy & Stella premiered at Summerhall (Paines Plough) during the 2022 Edinburgh Fringe, produced by Francesca Moody and Kater Gordon, co-directed by Brittain and Fabian Aloise (also choreographer), with musical direction and arrangements by Jones.

Kathy & Stella was expanded for a 2023 UK tour, returning to the Edinburgh Fringe (Underbelly) with a 90-minute iteration, followed by a two-act version at Bristol Old Vic and HOME Manchester, produced by Moody and Gordon in collaboration with Fiery Angel and Wessex Grove.

[14] Reviews of the West End production ranged from "bloody good fun with a poignant message" (Radio Times)[15] and "a certified homicidal hoot" (WhatsOnStage),[16] to "Kathy and Stella left me dead inside" (The Evening Standard).
