Calamity Town / Dragon's teeth

Wrightsville, a typical American town, buried in the great American heartland, up to its neck in good old American corn. The well-respected Wrights: daddy Wright is the town banker, Momma Wright is the town social lioness, daughter Patricia the town beauty, Nora the town recluse, Lola the town scandal. Ellery has to find out which of the Wrights is the town poisoner, while defending himself against a charge of murder.
