Death of a Cozy Writer : A St. Just Mystery

From deep in the heart of his eighteenth century English manor, millionaire Sir Adrian Beauclerk-Fisk writes mystery novels and torments his four spoiled children with threats of disinheritance. Gathering them all together for a family dinner, he announces his latest blow - a secret elopement. Within hours, eldest son and appointed heir Ruthven is found cleaved to death by a medieval mace. And soon Sir Adrian himself is found slumped over his writing desk - an ornate knife thrust into his heart. Trapped amid leering gargoyles and stone walls, every member of the family is a likely suspect. Using a little Cornish brusqueness and brawn, can St. Just find the killer before the next-in-line to the family fortune ends up dead?
