I like the Continental Op. But he is a failure in The Dain Curse. It's not his fault. He is in there punching, kicking and stirring things up, taking names and making notes as usual but the story is a mess. And the Op can not save us from Hammett's mess.
He tries though. “...You don't catch murders by amusing yourself with interesting thoughts. You've got to sit down to all the facts you can get and turn them over and over till they click.”
There are the stolen diamonds and the two murders that introduce Gabriell Leggett to us. She is a Dain family descendant and the recipient of the family curse. Following these murders she tries to hide from the curse in the midst of a religious cult only to be followed by the curse and the Op. There are two more murders and several murder attempts before the Op gets her to safety.
Safety is a relative thing when Gabriell is around. She marries her fiancé and they try hiding in a small town below San Francisco. The newlywed husband is the first of three more deaths, Gabriell gets kidnapped and a hand grenade almost gets the Op. Oh, and then the Op helps Gabriell kick her morphine habit cold turkey. And at that point we are still looking for the person or persons behind all the killing. Eventually the Op ties it all together for us.
The Dain Curse reads like three good Op short stories wired together to make a novel. The best thing I can say about it is Hammett follows it up with The Maltese Falcon.
