Dead Broke. Lana Denae Mysteries, #1

It was the perfect murder... almost. An elderly woman is found murdered in her apartment. Cause of death; a single gunshot wound to the chest. The only door is locked from the inside. There are no signs of entry, no bullet holes in the walls, and no weapon is recovered from the scene. That's when Detective Lana Denae of the Portland Police Bureau is assigned the case. The investigation gets off to a slow start until she realizes there is more to the story than a single random murder.
Someone is looking to rake in a profit to the tune of more than a million dollars, and they are willing to do whatever it takes to get it. Lana is determined to stop the killer before he strikes again but with limited evidence, finding just who is responsible is more difficult than she imagined.
