Who is more dangerous? An enemy, a friend, or a lover? When Bonnie Graham arrives at her boyfriend’s apartment in London, she is horrified to discover a dead body in a pool of blood on the floor. But she doesn’t call the police. Bonnie hides the corpse and then carefully wipes away any evidence she was ever there. Bonnie is a music teacher who spent a long, hot summer in London rehearsing with a band to play at a friend’s wedding. It was supposed to be fun, but the band members find the complicated knots of their friendships—some old, some new—unraveling as the days themselves unwind. What was meant to be a summer of happiness, love, and music turns deadly as lovers betray one another, passions turn murderous, and friendship itself becomes a crime. Everyone tells lies. But is anyone prepared to tell the truth to uncover a murderer?
