Christmas. Ghosts. Murder.

It's nearly Christmas in Oxford and Detective Inspector Bridget Hart is enjoying a rare day off at Oxford's Christmas Market. A ghost tour seems like a fun way to round off the day. Until, that is, a brutal murder brings the evening to a tragic close.

Torn between work and family commitments over the festive season, Bridget soon discovers that the ghost of Christmas past is reaching out to the present with fatal consequences.

Not everyone believes in the season of goodwill to all men, and with a real-life, flesh-and-blood killer at large in Oxford, Bridget races to solve the case in time to prevent yet more murders.
