When a young woman knocks on Palmer's front door one evening and asks him to find her an alibi for a particular evening sixteen months previously, Palmer thinks it will be an interesting case. Time is of the essence and Palmer wastes no time in getting started. Within hours his worst fears are realised and he begins to understand that this will be anything but a routine case. Palmer had no idea when he took on the case that finding an alibi for the young woman would be the least of his problems. He could never have envisaged the case would leave a good friend fighting for her life, nor could he have anticipated he would be seduced by the charms of a masseuse. Equally the trail of deaths that lead to the conclusion of the case could not have been foreseen.
