Unexpected challenge

HARRIET BLUSHED AT THE MEMORY...

Of how it had felt to have that dreadful man touch her. How he had at first thought she was a boy! Rick Dawson, a vacationing American who'd just arrived at the airport in London, climbed into Harriet's car thinking it was a cab. Obligingly she'd driven him to his destination, and then he'd accused her of stealing his wallet. He'd manhandled her, and she'd been struck dumb with shock. Later she thought of all the snappy, cutting comments she could have made. Oh, if only she could get a second chance with this infuriating enigma of a man. There'd be nothing dumb about her then!
