When Abigail Craig’s friend, retired solicitor Alasdair Mills, is burgled and his prized possession of a pair of Sir Walter Scott’s slippers is stolen, her life changes forever. The police have no leads so Alasdair convinces Abigail that they should do some investigating to track down the thieves themselves. Added to that, Abigail has a new lodger who is about to embark on a new career of her own, and Alasdair’s wife, Sophie, is up to her eyes organising the inaugural "High Tea in the Park" event in the city. When Abigail and Alasdair stumble into something more than they expected, and Alasdair goes missing, things not only take a turn for the worse but threaten to derail the biggest event to hit Stirling for decades.
