Adorable procedural whodunnit spiced with a love/lust at first sight over a legendary diamond. That's the plot. What makes me give it 4 stars (It's more like 3 3/4 stars but I rounded up the number)? Two very compelling leads. Fiona is competent, level headed, professional in her job, goes after what she wants and knows her limitations. DC is strong, level headed, professional in his job, goes after what he wants and knows his limitations. It's cheesy but they complete each other. The plot is not accessory to the story, instead it's used to showcase the leads strengths and weaknesses. I liked this one a lot.
