A suspicious death has the hallmarks of witchcraft in this locked room mystery by a master of the genre. When Edward Stevens, an editor at Herald and Son's publishing house, learns of the mysterious events that befell his neighbor's rich uncle, he shrugs off their seemingly supernatural circumstances. He's a logical man and doesn't give much credence to claims of a ghostly figure visiting the man before his death, or the witch's ladder discovered under his pillow after he passed. But as suspicions of strange murder begin to creep in, it becomes harder for Stevens to ignore their eerie potential. His neighbor breaks into the cement-sealed crypt where his uncle is buried, only to learn that the corpse has vanished. Witness testimony further implicates the intrusion of the spirit world into the affair of the murdered uncle, and unsettling echoes of the past into the present push things even further past Stevens' understanding of reality. Will the events be logically explained, or is there something unexplainable at work? The answer lies in the pages of this atmospheric and haunting puzzler, which finds Carr, the master of the locked room mystery, operating at the peak of his powers.
