The village of Plummergen is abuzz with excitement. A television crew has arrived in search of an apple--not just any apple, but the rare Plummergen Peculier, to be spotlighted in a special show on British food. At the same time, the police are on a search of their own for the elusive antique thieves who have burglarized a number of houses--and murdered an innocent man in the process. In the middle of it all is Miss Seeton, who will trip up the troublemakers in her inimitable style--and, quite unwittingly, become the apple of Scotland Yard's eye.
