It's a big day at Christophe et Cie, a small couture house off Regent Street. Mr Bevan will announce which of his staff he is sending to France to be general manager of a new branch in Deauville. Will it be the talented and elegant Miss Doon or the loyal and long-serving Miss Gregory? Perhaps senior saleswoman Irene or showroom manager Dorian will get the job. Events take a dramatic turn over a lunch of rabbit curry when Miss Doon collapses and dies, poisoned by the oxalic acid crystals that another employee, Rachel, has been using to clean her hat. Inspector Charlesworth and Sergeant Wyler have a murder enquiry on their hands.
