For those who dedicate their lives to "chasing the ghost," searching for that elusive moment of perfect connection on the dance floor, tango is a drug. A drug that proves fatal. When a much-hated member of the Atlanta tango community is stabbed in the middle of a dance, the last thing tango instructor Antonia "Ant" Blakeley wants to do is help the police work out how someone could have struck the fatal blow unseen. Her troubled nephew is first on the list of suspects, and she`ll do anything to protect him. Unfortunately for her, she`s up against Detective Sam Morrow, a former marine who will do anything to get to the truth. Only one of them will get what they want.
