The lights go out in the studio of wealthy artist Eric Stannard. When they come on a moment later, the artist is dead, his heart pierced by an etching needle. But who is the murderer? The artist's wife, jealous of her husband's young model? The model, who felt pressured by the unwanted attentions of the artist? The artist's son, who was in love with the model? Or the neighbor, who was in love with the artist's wife? An impossible crime for which Alan Ford must find a solution in Faulkner's Folly a classic Carolyn Wells mystery.
