The story starts strong with a classic Noir set-up (woman walks into dive bar looking for her lost sister and gets a big dose of trouble), but doesn't proceed strongly from there.  The relationships between the characters are unclear.  Every character seems to be a stereotype of some sort.  The realism factor is missing.  The ending is unclear.  With a stronger editorial hand, the author could have had something here.  But it takes more than visits to dive bars, missing women in peril, and characters who live on the wrong side of the law to make a good Noir story.
