A wealthy heiress dies. She jumped off the balcony of her elegant home (or did she?). Was it suicide... or was it murder? The twist: she was reading one of Ellery's own murder mysteries at the time and she died exactly the same way as the victim in the book.

Simon Brimmer once again fingers the wrong culprit in this tale about the murder of a socialite who was apparently leading a double life. The case has its underpinnings in events that happened in 1922 France. It's a hard road to the solution and Ellery takes the correct one as usual.
