Have the smugglers made a grave mistake?

Customs & Excise are tracking a gang of cigar-smugglers who operate on the quiet Kent coast near Plummergen, home to retired art teacher Miss Emily Seeton. Their attempt at a midnight ambush goes wrong, and a man is found dead.

As Miss Seeton sketches the most notorious tomb in Plummergen churchyard - the one built for 19th-century smuggler Abraham Voller - she meets a young American tourist. He claims to be a descendant of the Voller family, but is he a truly innocent ancestor-hunter, or do smugglers inherit their trade?

When the school concert includes a performance of Kipling's "A Smuggler's Song" it begins to seem that everyone is at it ... but we can rely on Miss Seeton to ensure that the police will get their man, and the smugglers' dreams will go up in smoke!

Serene amidst every kind of skulduggery, this eccentric English spinster steps in where Scotland Yard stumbles, armed with nothing more than her sketchpad and umbrella.
