This starts out like how I would think an typical old detective mystery movie would start. After closing time, the detective is in his office ( I pictured that old frosted glass from the black and white films), he's a down on his luck, up to his eyeballs in debt type, living on the couch there in his workspace...when he hears the sound of a woman's footsteps approaching. In walks the dame...yeah that's how it goes. 
 Some of it was so 'to be expected' but there was also enough unexpected parts to balance that out. I liked it but I didn't love it. Though I will definitely read the next one - I'm not going dying to read it RIGHT NOW, so who knows when I'll get to it. Know what I mean? Hence why I think this one is just OK. 
 I'm hoping that the series will get better because a good buddy of mine said he really enjoyed them. I did like how short and sweet the book was though. It was just something quick and easy to munch on and the next few also look pretty slim. It definitely shows promise.
