The Woman at Belguardo — Margaret Erskine

'Beware of passion that's both meek and wild'...thought Scotland Yard's Inspector Septimus Finch about the man who murdered lovely Lisa Harcourt. Tomorrow her divorce from elderly Francis Harcourt would have been final; tonight she lay horribly dead. It was, in fact, a question of numbers. Many men loved her, two wanted to marry her, and one of them killed her. At least someone did...someone who entered the magnificent mansion called Belguardo, made the footsteps the maid heard crossing the hall, and left Lisa in a pool of blood as red as the rose tucked in her bodice. The local constables blamed her jilted lover, but Inspector Finch suspected that her fiance, her doctor, her nearly ex-husband, or even her butler did it. And what's more, he was sure that the murderer would kill again.
