Cassie's Favour — Anne Holman

Cassie Wilkinson is having a hard time caring for her papa, an eminent physician, after he suffers a stroke. So she is understandably reluctant to take on the care of Viscount Breckonridge's two greyhounds while he is abroad - although he does not give her much choice. When the dogs go missing, Cassie feels obliged to discover what has happened to them... The mystery involves kidnap and blackmail, and is solved by the spirited Cassie - who finds love too.
