The Message of the Mute Dog

It's WWII-era England, and amateur supersleuth Jane Amanda Edwards pokes her astute nose in, again, when an arsonist strikes the defense plant where her brother works, and murders the owner. The police captain, her brother Arthur (who's a suspect) and just about everyone else in town defers to Amanda's bull-dozing intervention, and sure enough she's soon hot on the trail of a foreign plot in this reprint of Charlotte Murray Russell's (Cook Up a Crime) 1942 The Message of the Mute Dog.
