Mary Burchell and her sister saved Jews from the Nazis during World War II, funded largely by her writing. She wrote novels from 1936 to 1985. She was my favorite romance writer when I discovered romance novels in my teens. I've been rereading and reviewing a box of her books that I kept.
One Man's Heart is one of her best. It is a highly unusual vintage Harlequin romance. We meet the heroine, Hilma, as she establishes an alibi before breaking into a man's flat. A few years earlier, she wrote a compromising letter to a man. Now, she is engaged to a dull, rich, older man who would not understand or forgive the letter. She is breaking in to steal it back. Only she has chosen the wrong flat, and she is caught by the man who lives there.
Although he threatens to call the police, they feel an immediate attraction. When she explains why she has broken in, he understands. He himself, in danger of losing his ancestral home, is also engaged - to a charming, rich, cold woman who wishes to buy the ancestral home and its owner too.
They part without knowing each other's names, but as they move in the same social circles they run into each other. There are ramifications from the night they met that threaten both of their engagements. And their growing attraction to each other is harder and harder to resist. They resist because they both want money and neither has any.
Hilma and Buck are two attractive scoundrels, not normally the heroine and hero of a genre romance. They have surprising depth, one of Mary Burchell's strengths. I recommend One Man's Heart to anyone who enjoys vintage genre romance.
