When retired solicitor Alasdair Mills is burgled, the robbers leave behind his money and valuables, only stealing a pair of slippers that once belonged to Sir Walter Scott. Dismayed that the police are not taking the theft of his prized possession seriously, Alasdair turns to his old friend, the cunning Abigail Craig, for help. Donning disguises and hunting for clues, the pair turn detectives to track down the thief themselves. But the investigation takes a turn for the worse when Abigail and Alasdair stumble across something more sinister and realise there is far more to this case than a pair of missing slippers.
When Abigail Craig's friend, retired solicitor Alasdair Mills, is burgled and his prized possession, a pair of slippers that once belonged to Sir Walter Scott, 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 fresh career of her own, and Aladsair'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 across something more sinister, and Alasdair goes missing, things take a turn for the worse and threaten to derail the biggest event to hit Stirling for decades.
