In the quaint English town of Hoslewit, the biggest names in crime writing have congregated to celebrate all things bookish and murderous. Author Jane Hepburn is determined to make her time at the Killer Lines festival worthwhile. This is her chance to change her fortunes and make her fictional Private Detective Baker a household name. And if she has to resort to sneaking into the book tent after hours to rearrange some books so hers are front and center, so be it.

But when Jane encounters the dead body of renowned (and reviled) literary agent Carrie Marks, the festival takes on a decidedly different tone. Joined by Carrie's newest client, debut novelist Natasha Martez, and the agency's hapless intern, Daniel Thurston, Jane decides to put her fictional sleuthing skills to use in the real world--she's going to solve the murder. But the list of suspects is long: seemingly everyone at the festival has a motive to kill Carrie, and the more Jane and her new friends investigate, the closer they come to a dangerous truth--one that's stranger than fiction.
