Unrelated strangers are being murdered in a brutal fashion. At each scene, the killer is leaving a chess board. The deaths seem to represent moves in some ghastly game. Now it's up to crime-scene cleaner Mike Chambers, with the help of the police, in the form of his friend, DC James Worth, to track down the killer and stop the trail of carnage. The Grandmaster is the latest output from the mind of Calum Kerr, author of Undead at Heart, Braking Distance, Lost Property and 31. This book is the third in the 2014 Flash365 series.
