Newly minted PI Emma Holmes and her partner Sam Collins are settling into their business when music-hall star Verity Malone hires them to prove that she didn't poison her husband. In this 6th outing (after Now You See Them), the Brighton police are already on the case, putting Emma in direct competition with her husband, police superintendent Edgar Stephens. Soon Emma realizes that Verity's life intersects with her own—most notably in their mutual connection, Max Mephisto. Now Max's Hollywood-actress wife Lydia joins Emma and Verity to find the killer before he sets his sights on Max.
