Runaway Lady

the long version

"'I will hire you only on condition that you promise to do everything in your power to protect me.' With his curved Turkish sword, and dark, brooding looks, Harry Ward is a formidable adversary. Lady Saskia van Buren's life is in danger, so she has fled to London and hired him as her protector. But she soon finds herself longing for more than safety in his arms. Unknown to Saskia, Harry believes she's a Dutch spy - and he intends to bring her to justice. Only he's torn between duty and desire, and will do whatever it takes to keep Lady Saskia safe - even make her his convenient bride."--Publisher description.
