With the help of his French valet, Keegan escapes from prison, and decides to take hostage Lady Zoe Morgan, the sister of Foxworth Morgan. Zoe has lived the life of an invalid since a childhood illness, convinced by her nurse she is weak and frail. She is shocked when the Scot takes her hostage and leaves word for her brother to come for her in Scotland.
As they begin their arduous journey north, it appears to Keegan that despite her constant haranguing about her ill health (and, yes, that was annoying), the girl he has taken hostage is quite braw. So much so, she is able to escape Keegan, but then falls into the hands of a notorious smuggler who takes Keegan captive as well, hoping for a large ransom for both the girl and the Scot when he delivers them to the English in Scotland.
