Veronica's natural-historian beau, Stoker, has been away in Bavaria for months and their relationship is at an impasse. But when Veronica shows up before him with his brother, Tiberius, Lord Templeton-Vane, he is lured back home by an intriguing job offer: preparing an iguanodon for a very special dinner party. Tiberius has received a cryptic message-along with the obituaries of two recently deceased members of his old group of friends, the Seven Sinners-that he too should get his affairs in order. Realizing he is in grave danger but not knowing why, he plans a reunion party for the remaining Sinners at his family estate to lure the killer out while Veronica and Stoker investigate. As the guests arrive and settle in, the evening's events turn deadly. More clues come to light, leading Veronica, Stoker, and Tiberius to uncover a shared past among the Sinners that has led to the fatal present. But the truth might be far more sinister than what they were prepared for.

While investigating a man claiming to be the long-lost heir to a noble family, Veronica Speedwell gets the surprise of her life in this new adventure from the New York Times bestselling and Edgar Award-nominated author Deanna Raybourn. London, 1889. Veronica Speedwell and her natural historian beau Stoker are summoned by Sir Hugo Montgomerie, head of Special Branch. He has a personal request on behalf of his goddaughter, Euphemia Hathaway. After years of traveling the world, her eldest brother, Jonathan, heir to Hathaway Hall, was believed to have been killed in the catastrophic eruption of Krakatoa a few years before. But now a man matching Jonathan's description and carrying his possessions has arrived at Hathaway Hall with no memory of his identity or where he has been. Could this man truly be Jonathan, back from the dead? Or is he a devious impostor, determined to gain ownership over the family's most valuable possessions--a legendary parure of priceless Rajasthani jewels? It's a delicate situation, and Veronica is Sir Hugo's only hope. Veronica and Stoker agree to go to Hathaway Hall to covertly investigate the mysterious amnesiac. Veronica is soon shocked to find herself face-to-face with a ghost from her past. To help Sir Hugo discover the truth, she must open doors to her own history that she long believed to be shut for good.
