A Ghost in the Machine — Caroline Graham

SOME SECRETS ARE DEADLY IN THIS WORLD-AND THE NEXT...

Scrupulously honest and warm-hearted, solicitor Dennis Brinkley is about the most liked person in the peaceful country village of Forbes Abbot. His only eccentricity--restoring fearsome ancient war machines. So when he's killed by a cannonball from one of his contraptions, even Chief Inspector Barnaby believes it's a freak accident. Until an opportunistic medium claims Dennis is about to reveal his murderer to her...and soon turns up deceased herself.

Now, with two people dead and a possible witness missing, Barnaby must untangle the sinister doings and passionate obsessions underneath Forbes Abbot's vale of seeming tranquility. And the eminently rational chief inspector must uncover evidence of things not seen before time runs out--and a calculating killer forever gets beyond his reach.
