A murder is committed - victim and murderer unknown.A building society executive dies, apparently of suicide.Five dismembered body parts are discovered in widespread locations throughout Yorkshire. Five different police forces are investigating.Newly promoted Chief Superintendent Jonny Jackson and his Leeds based Murder Investigation Team are called in to liaise and assist with the inquiries and soon discover that the apparent suicide was faked and a murder had been committed. The dismembered corpse is identified and a connection between the two victims established.Once again, Jackson finds that the whole scenario has been constructed by the mysterious "Simon" who became an arch-enemy of his in a previous case. Simon has the ability to enter the minds of the actual perpetrators of the crimes and, as yet, remains undiscovered. For this is only a game for Simon; he cares not for the victims or his 'helpers', only his own self-satisfaction on outwitting the police.
