Cheating Death

Horatio and his team of CSIs investigate the murder of a con man who conned married women into sex to steal their money. They wouldn't go to the police because they didn't want their husbands to find out that they cheated on them. They are found in a hotel by the manager, the woman covered in blood with no memory of what happened, and the man cuffed to the bed post and stabbed to death. The team believes it was either a revenge killing by one of the women or their husbands, or could it be something more?
