The Basement by Stephen Leather

Every once in a while you come across a story that has an interesting twist.  This was one of those.  I kind of figured it out about 1/2 way through and was sure about it a few pages later but it still was a great quick read that kept my interest.  I only wish it was longer.  It had great potential to be a full sized novel if the characters and the storyline had been fleshed out and expanded.  But still, it was an entertaining and enjoyable read.
