What Happened That Night (A Novel) by Nicci French

From international bestselling master of suspense Nicci French comes a hair-raising locked-room thriller about a group of old university friends with a killer in their midst.

Old friends, new secrets, one deadly reunion.

Tyler Green, convicted of murdering his friend Leo at a student house party in 1993, has been released after almost three decades in prison. He has always protested his innocence.

On a warm evening in London, Tyler summons eight of his university friends who were present on that fateful night. Is it just a reunion - or something else? With wine—and accusations— flowing liberally, the reunion descends into violent chaos, and one friend will end the night with their throat slit in the upstairs bedroom…the same way that Leo’s was in 1993.

When Detective Inspector Maud O’Connor gets called to investigate, she has her own doubts about Tyler’s guilt, despite what his old friends, the rest of the Metropolitan Police Force, and even the Home Secretary would like her to believe….
