On the video, someone comes in waves a gun around, takes money from Chinese gamblers, and shoots Trent Annunzio at close range. The guy in charge defensively points out that they got robbed too. Holmes says there's got to be another video because the shooter clearly didn't have a mask on at the front door. He runs roughshod over the inevitable objections about how they want to handle it themselves. So the next video shows a great full-face shot of some guy, just before he puts on a ski mask. Holmes: "Detective Bell, I give you Trent Annunzio's murderer."

At the police station, Holmes flips through mug shots looking for the face from the video. Watson thinks he's going too fast, but he insists he is merely taking the minimum time required. Watson gives him some tea, which is neither the coffee he asked for nor the kind of tea a British person likes. Watson explains that there are some Chinese herbs in there, but she can defend it from a medical standpoint. Because he's sick, remember? To change the subject, Holmes has Liam's arrest record. Just in case she wanted to be sure about him. Bell comes in and reports that he's identified the suspect as Raoul Ramirez, who was recently in Sing Sing. Watson goes with him, but Watson lingers with Liam's arrest record. I don't think she's supposed to have that.

Raoul is in the interrogation room and Bell is going through the evidence against him. Since it includes clear video of him going into the gambling den he shot up and a bunch of wallets they found in his garbage, including Trent's, it doesn't look great for him. Raoul says he was hired by someone, which is really all he can say at this point. His story is that he came home last week and found an envelope with a thousand dollars in cash. And then a mysterious voice on the phone said he'd get nine thousand more for killing Trent by shooting him once in each eye. The plan was for Raoul to do him tomorrow night as he walked to his car. But after following him around, he figured, you know, might as well rob a gambling den at the same time. He never met the guy who hired him because all the communication was through scrambled-voice calls or texts. Raoul happily lets the police have his phone, although I don't think "I only killed that guy for the money!" is the sort of plea that gets you completely off the hook.
