Beth Baxter, owner of a not-very-successful book shop, is planning her marriage to Karl — or, at least she was. Without warning, Beth suddenly finds herself embroiled in a sinister series of events that threaten to destroy everything she holds dear.

All seems lost for Beth until she receives an offer of help from an unlikely visitor — a former gangland fixer by the name of Clement. However, there’s one minor issue in that Clement claims he died in 1975 and been sent to help Beth to atone for his actions in a previous life.

With just seven days to avoid a fate she’d rather not contemplate, Beth reluctantly joins her deluded, politically-incorrect companion on a quest across London in search of a solution. Will this unlikely partnership succeed? Will Clement ever come to terms with paying five quid for a pint? And will Beth ever learn the truth about who sent Clement?
