The Law and The Lady by Wilkie Collins

I was interested in reading this since it is described as the first mystery with a lady detective. Having enjoyed The Moonstone and the Lady in White, I was surprised at how dated this book is. The lady detective sets out to clear her husband's name of murdering his first wife and gets nothing but discouragement and anger from her husband and his mother. She carries on because she says she loves her husband so much. Frankly, it's hard to see why she is so devoted. He's a bit of a wimp and absolutely too sensitive for words. I wanted to slap him! Ultimately, the mystery is solved but the ending is absolutely unsatisfying!
