The mastermind is dead. His work is just beginning.

Detective Cora Cross thought Orpheus was a ghost-a myth the Pact used to keep the city in terror. But the masterpieces have returned, and this time, the performance is louder, bloodier, and more public than ever before. Every body staged in the city's squares carries a message that sounds like it's coming from beyond the grave.

To stop the rising panic, Cora is forced into an uneasy alliance with Gabriel Lyon, a man who knows too much about the Pact's earliest rituals. Together, they dig into the group's secret origin, only to find a conspiracy that connects the current citywide chaos to the one cold case Cora can never escape: the murder of her own sister.

The killer doesn't just want an audience anymore. He wants a resurrection. And he's making sure Cora Cross has a front-row seat to the slaughter.

The clock is ticking toward the ultimate exhibition. Continue the Hourglass Series today.
