A Worthy Charade — Vivian Harris

Was the provocative Hope Bottomsly, the ingenious Betsy Hatfield -- or Miss Katherine Tarkington from the Blue Hills of Devon? That was for Lord Milford to discover! Kate had taken loving care of her sister and brothers since her parents' death. Now she had come to London to chaperon the lovely Gwen and plan a wedding. Before the week was out, she had placed herself in Milford Hall in the guise of governess. She meant to learn all she could of the man her sister meant to marry. The day must come when Lord Milford would discover her true identity. But he was Gwen's intended. He must never learn that he had stolen Kate's heart!
