Me: Cut the shit. What do you want?
 
 Keep him talking…
 
 While the dots move as he formulates his reply, I flip over to one of my apps I’ve tweaked to triangulate a number. It won’t tell me exactly where this person is, but it’ll give me an idea.
 
 Unknown Number: To talk about last night.
 
 Me: What about last night?
 
 Unknown Number: Did you know she was there? Right under your nose and you missed it?
 
 My blood runs cold. It’s a lie. If Calista had been there, I’d have been able to sense it—to feel my sister’s presence.
 
 He’s taunting me, distracting me from discovering who he is and where he’s at.
 
 Me: Bullshit.
 
 Unknown Number: I don’t lie.
 
 Me: I don’t know you, therefore I don’t believe that.
 
 The app spins slowly after I paste S’s number in. Since he appears to be watching me, I don’t think he’s using a computer program this time. I think he has a bag full of burner phones he uses and tosses after our texts.
 
 My bars are low in this area. I stand and walk a few steps to see if it helps. Another bar forms, so I stay in that spot, waiting for the app to pinpoint his location.
 
 Unknown Number: You know me, friend.
 
 A chill that has nothing to do with the icy weather freezes me to my marrow.
 
 Me: I’m not your friend. Why hide behind anonymity?
 
 Unknown Number: I know how much you love games, Caius. Isn’t this fun?
 
 Me: Toying with me isn’t fun.
 
 Finally, the app stops spinning. Dozens of possible locations begin to populate. While it does that, S replies again.
 
 Unknown Number: Don’t worry. All will be revealed soon.
 
 Me: Not soon enough.
 
 Unknown Number: I know where she’s at. Do you want to know where?
 
 Of course I do, but I don’t trust S. He can’t even show himself.
 
 My phone buzzes, but this time alerting me that all the possible locations have been added. I press the “triangulate”button and wait for it to make a likely determination of where the phone is at.
 
 I need to keep him talking.
 
 Me: Tell me.
 
 Unknown Number: I don’t have to. You’re hot on the trail.
 
 Buzz.
 
 Two blocks north.
 
 I start jogging in the direction of the address while continuing my conversation with S.
