Mrs McCarthy (Sorcha Cusack) is delighted to have her daughter Joselyn (Eva Feiler) visit but Father Brown (Mark Williams) suspects there's something untoward about her unscheduled appearance. Meanwhile at The Crimson Feather club, manager Maurice (William Travis) lends some money to one of his dancers, Verity (Letty Butler). She's going to be a very busy girl paying it off... The next morning Mrs McCarthy finds that Joselyn has disappeared - only a note and long red feather remain. Bunty (Emer Kenny) examines the feather and says that one place springs to mind... Bunty infiltrates the club and is employed as a dancer, spotting Joselyn inside. Father Brown manages to persuade Maurice to let him have a word with her but in her dressing room they find Verity's dead body. Janek (Peter Stark) a polish bouncer stands over her with bloodied hands, but is he really responsible for her death?
