Roberta Leigh - Two faced woman

"Miles Gilmour's reaction to the news that the company he ran was now the property of an American socialite was predicatble. Catherine Barlow knew nothing of big buisness, and he had no inclination to wait around while she learned. But Cassie Elliot, his new and very attractive secretary, was a different matter. What Miles didn't realise was that they were one and the same woman! Cassie knew she was playing with fire. But she was confident she could cope. Until she fell in love with the man."
