Cache on the Rocks — Michael Sellers

Although the coroner returned a verdict of misadventure when Tag Chumsty's body was found on a Cornish beach, his father refused to believe his son had died by accident.Of the two alternatives to accidental death (suicide or murder) Cal soon discounts the former when he discovers the dead man had been running an apparently successful business and had been spending much of his free time with an extremely shapely blonde. Which left him with murder and why on earth was Tag in Cornwall anyway?
Cal's inquiries into Chumsty's movements before his death seem to upset a very diverse lot of people and upset them to the extent of wanting him bought off.
Such offers merely increase Cal's determination to fulfil his obligations, even when the offers begin to get more violently persuasive.
