The Secret Ingredient: A British Mystery

This is a short story. When amateur sleuth Emily Castles and her friend Dr. Muriel meet Gareth Crabbe, newly-appointed poet-in-residence at Brixton's windmill, he reveals that an intruder has been breaking in at night. While Emily and Dr. Muriel try to discover the identity of the intruder, Gareth must find the inspiration to write a poem, or funding for his residency will be withdrawn and the Gala Open Day at the windmill will be ruined.
