Fair play A novel

Hegarty's brilliant debut kicks off with a murder mystery--themed New Year's Eve party at a posh London Airbnb. The guests of wealthy siblings Abigail and Benjamin include work acquaintance Barbara; Benjamin's childhood friend, Stephen; bankrupt spoilsport Declan; extravagant couple Cormac and Olivia; and Dorcas, the maid. The morning after the festivities, Benjamin is found dead in his locked bedroom. The doctor who arrives on the scene suspects suicide, but a skeptical Abigail hires famous PI Auguste Bell to investigate. When Benjamin and Abigail's eccentric aunt arrives to console Abigail, she, too, is unconvinced that Benjamin took his own life, and she partners with Bell to solve the crime. "There are too many clues," complains a frustrated Bell, who asks absurd questions ("Does this house have gas central heating?") of each suspect in an attempt to sniff out the murderer. A distraught Abigail turns against each of her friends until Bell finally announces the name of the killer. Or does he? Readers, especially fans of Richard Osman, will happily go along with the plot's many reversals and take heart in its surprisingly tender conclusion. Hegarty's wonderfully eccentric characters, expert knowledge of classic whodunits, and ability to balance silly hijinks and serious emotional stakes mark her as a writer worth keeping tabs on. For mystery lovers, this is a joy. Agent: Allison Malecha, Trellis Literary. (Apr.)
