Plot summary

"As the story opens, free-lance writer Ross Harte is writing a magazine article on the modern detective story, and most of this article-to-be is included in the first chapter."

When a magician is found dead inside his locked and (thoroughly) sealed apartment, the police call in Merlini to help explain the impossible, "perhaps on the theory that it takes a magician to catch one."
