This was an absolutely enjoyable episode.
First off, the splitting of the team on three cases is great, because it gives us a great look at the characters.
Second, we've got the one-off character of Detective Kalie Maka to give us a look at Danny's player rep. Personally, I love Kelly Hu, and though Anna Belknap's Lindsay Monroe was a perfect fit for Danny, Kelly would have been great as a love interest.
Then we've got the inestimable T.J. Thyne playing the rare books seller. As always a wonderful performance by a vastly underrated actor.
Not to mention the gigantic amount of puns dropped by absolutely everybody (my favorite was Sheldon Hawkes's description of the smell as a "James Brown. It's funky.")
Lastly is the two more shocking culprits. First off, the kid in Mac and Stella's case is clearly a budding killer. They definitely got that one off the streets early. Then there's Aiden and Flack's. A frigging blue-ice bomb to the noggin. Only in a Bellasario.
