A collection of short stories all involving Moris Klaw, the dream detective, who has the unusual crime-solving technique of sleeping on his “odicly sterilized cushion” at the crime scene and allowing lingering thoughts to form an “etheric negative” in his mind.
Most of the stories are locked-room theft and/or murder mysteries, but some are quite straight forward and don’t involve detective work at all, dream or otherwise. In “The Potsherd of Anubis”, for example, Moris Klaw poses as a French archeologist to steal a valuable Egyptian artifact from an antiquities collector. That’s it. It’s not even a mystery — the collector was quite sure his new neighbor was there to steal the sherd all along. All except the final story feature a crime of some sort. In the last, a man rather obsessed with Egyptology attempts to re-create a ritual from the cult of Isis and invoke the goddess to appear.
