In "The Escher Twist", the search for a mysterious woman in a green coat, glimpsed briefly at an art exhibition, leads Cambridge professor Homer Kelly and his wife, Mary, into an Escher-etched labyrinth, where every intriguing line, curve, and angle points to murder.

Jane Langton is the author of fifteen other Homer Kelly mysteries, and a well-known children's author.

Definitely, both artwork of book titles are inspired by art of Istvan Orosz.
