Miss Hamilton's Hero — Nancy Lawrence

A THIEF OF HEARTS.
Nothing exciting ever happens to Miss Penelope Hamilton. Nothing, that is, until she is sent to live with her grandmother, the Honorable Mrs. Kendrick-- and her carriage is held up by the most wanted brigand in all of England! But that's just the beginning of exciting adventure for Pen, for she soon discovers that Mrs. Kendrick's beautiful estate is not exactly what it seems, and neither is her serious--and handsome--step-son, Owen. Soon Pen is snooping around the house and closely following Owen's every move-- something that isn't altogether unpleasant.

OR A HEART OF GOLD?
Owen Kendrick is beginning to suspect that the lovely, seemingly guileless Pen has some secrets of her own. Someone has been pilfering things from the house, and Pen has been acting a bit funny, especially since that kiss they shared. Could there be someone else in the manor? Could there be someone else in Pen's affections? Or has Owen been the most successful thief--at stealing her heart?
