This was a well-written book of its age and type (it was written in the 1920s), with just a few places where one grinds one's teeth at the ideas about female psychology back in the dark ages. (The heroine actually tells someone that women in love enjoy doing things they dislike if the man they love enjoys the thing in question!) I give it 4 stars for suspense and enough red herrings to make it very interesting. It does have the usual love at first sight nonsense, but there is usually a couple in her books who bond over the trials and tribulations...
