Beautiful and new in town, Ellen Langston-Jones doesn't have any enemies. So, when she's found dead in the communal gardens, Inspector Witherspoon quickly narrows the field of suspects down to one: Lucius Montague, who was seen threatening Mrs. Langston-Jones shortly before her death.
The Inspector and all of London are positive that he's the killer, but Mrs. Jeffries has doubts. Her biggest problem is that Lucius Montague is a very disagreeable character and no one—including Inspector Witherspoon's staff—is inclined to save his skin. Now, she must turn the tide of the investigation . . . or watch an innocent man take the fall for the real killer.
