Kill Your Darlings by Josh Lanyon

At this mystery conference, murder is more than just another plot twist…

Nobody likes conferences, but they’re part of the job.

Millbrook House senior editor Keiran Chandler has spent years curating the best voices in crime lit, but when an unsolicited manuscript is handed to him at the Noir at the Shore mystery conference, truth collides with fiction. I Know What You Did is more than just another slush pile submission—it’s a direct threat.
U.N. Owen seems to know what really happened in Steeple Hill all those years ago. Who is Owen? How does he know these things? Clearly the mysterious author is after more than a book deal. But what?
With a potentially career-ending publishing merger on the horizon, the end of his affair with bestselling author and former homicide detective Finn Scott, and not so subtle threats from someone in his past, Keiran has a lot bigger problems than coming up with something witty to say on discussion panels.
