Stewart "Hoagy" Hoag is thrilled after a meeting with his editor, Norma, where she predicts his new book is sure to establish him as the next great American author. But his happiness is short-lived when at his next meeting with Norma, she asks for his help in discovering who is behind a series of increasingly threatening letters sent to her attention.

Norma herself is not overly concerned about the letters, but her boyfriend, Detective Lieutenant Romaine Very of the NYPD, thinks the threat of violence against Norma should not be so easily dismissed. Very feels the combination of Hoagy's detective skills and knowledge of the underbelly of the publishing world make him the perfect person to investigate the matter. Plus, Hoagy is a friend he can trust to take care of the love of his life. Hoagy agrees, if for nothing else than to ease the minds of two people he cares about very much. After all, this is likely to be nothing more than a dramatic gesture from a frustrated writer.

But as Hoagy and his trusty basset hound Lulu investigate, the threats move beyond the written word, making it clear that someone out there is determined to write a vicious ending to Norma's life. This is not the return to the literary world that Hoagy dreamed of, but he is determined to unravel the mystery before the author of these crimes gets the last word.
