Margaret Annister is slated to die in Nevada City's gas chamber but she's not too worried. She's been given a drug by the police matron that takes away all cares and concerns.

Throw in local attorney Croxson Kalver who knows she's been set up and you have the makings of a webwork mystery only Harry Stephen Keeler could have penned.
