Inspired by Agatha Christie's real-life Detection Club, a murder among a group of golden age mystery writers meets a second chance romance in this debut novel from author Jackie McMahon.

London, 1930. Lucy Hubbard is on the cusp of achieving her dreams. With her first mystery novel debuting with strong sales and glowing reviews, she's been invited by Horace Hazelmoor, the king of crime fiction, to join his elite group of writers—the Cloak and Dagger Club.

Thrilled at the opportunity, Lucy finds herself swept up into Horace's glamorous world at the Ritz hotel. She's even willing to put up with the inconvenient presence of her former fiancé, Frank Murray, the club's rising star who is on track to eclipse Horace as Britain's most popular crime writer.

But when Horace is found with a knife in his back, Frank is the police's prime suspect. Despite their complicated history, Lucy knows he's not capable of murder. With suspects galore and the danger rising, these two mystery writers must race to solve the crime—and fight their lingering feelings for each other—before the murderer strikes again.
